Hi All, In this article we are going to setup Laravel on CentOS 7 and Ubuntu 15.04. If you are a PHP web developer then you don’t need to worry about of all modern PHP frameworks, Laravel is the easiest to get up and running that saves your time and effort and makes web development a joy. Laravel embraces a general development philosophy that sets a high priority on creating maintainable code by following some simple guidelines, you should be able to keep a rapid pace of development and be free to change your code with little fear of breaking existing functionality.

Laravel’s PHP framework installation is not a big deal. You can simply follow the step by step guide in this article for your CentOS 7 or Ubuntu 15 server.

1) Server Requirements

Laravel depends upon a number of prerequisites that must be setup before installing it. Those prerequisites includes some basic tuning parameter of server like your system update, sudo rights and installation of required packages.

Once you are connected to your server make sure to configure the fully qualified domain name then run the commands below to enable EPEL Repo and update your server.

CentOS-7

# yum install epel-release

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

# yum update

Ubuntu

# apt-get install python-software-properties
# add-apt-repository ppa:ondrej/php5

# apt-get update

# apt-get install -y php5 mcrypt php5-mcrypt php5-gd

2) Firewall Setup

System Firewall and SELinux setup is an important part regarding the security of your applications in production. You can make firewall off if you are working on test server and keep SELinux to permissive mode using the below command, so that you installing setup won’t be affected by it.

# setenforce 0

3) Apache, MariaDB, PHP Setup

Laravel installation requires a complete LAMP stack with OpenSSL, PDO, Mbstring and Tokenizer PHP Extensions. If you are already running LAMP server then you can skip this step to move on and just make sure that the required PHP extensions are installed.

To install AMP stack you can use the below commands on your respective server.

CentOS

# yum install httpd mariadb-server php56w php56w-mysql php56w-mcrypt php56w-dom php56w-mbstring

To start and enable Apache web and MySQL/Mariadb services at bootup on CentOS 7 , we will use below commands.

# systemctl start httpd
# systemctl enable httpd

#systemctl start mysqld
#systemctl enable mysqld

After starting MariaDB service, we will configure its secured password with below command.

#mysql_secure_installation

Ubuntu

# apt-get install mysql-server apache2 libapache2-mod-php5 php5-mysql

4) Install Composer

Now we are going to install composer that is one of the most important requirement before starting the Laravel installation that helps in installing Laravel’s dependencies.

CentOS/Ubuntu
Run the below commands to setup ‘composer’ in CentOS/Ubuntu.

# curl -sS https://getcomposer.org/installer | php
# mv composer.phar /usr/local/bin/composer
# chmod +x /usr/local/bin/composer

5) Installing Laravel

Laravel’s installation package can be downloaded from github using the command below.

# wget https://github.com/laravel/laravel/archive/develop.zip

To extract the archived package and move into the document root directory use below commands.

# unzip develop.zip

# mv laravel-develop /var/www/

Now use the following compose command that will install all required dependencies for Laravel within its directory.

# cd /var/www/laravel-develop/
# composer install

6) Key Encryption

For encrypter service, we will be generating a 32 digit encryption key using the command below.

# php artisan key:generate

Application key [Lf54qK56s3qDh0ywgf9JdRxO2N0oV9qI] set successfully

Now put this key into the ‘app.php’ file as shown below.

# vim /var/www/laravel-develop/config/app.php

7) Virtua Host and Ownership

After composer installation assign the permissions and apache user ownership to the document root directory as shown.

# chmod 775 /var/www/laravel-develop/app/storage

# chown -R apache:apache /var/www/laravel-develop

Open the default configuration file of apache web server using any editor to add the following lines at the end file for new virtual host entry.

# vim /etc/httpd/conf/httpd.conf

ServerName laravel-develop
DocumentRoot /var/www/laravel/public

start Directory /var/www/laravel
AllowOverride All
Directory close

Now the time is to restart apache web server services as shown below and then open your web browser to check your localhost page.

CentOS

# systemctl restart httpd

Ubuntu

# service apache2 restart

8) Laravel 5 Web Access

Open your web browser and give your server IP or Fully Qualified Domain name and you will see the default web page of Laravel 5 frame work.

Conclusion

Laravel Framework is a great tool to develop your web applications. So, at the end of this article you have learned its installation setup on Ubuntu 15 and CentOS 7 , Now start using this awesome PHP framework that provides you a lot of more features and comfort in your development work. Feel free to comment us back for your valuable suggestions an feedback to guide you in more specific and easiest way.

Direct Admin is a Graphical User Interface (GUI) web hosting control panel that provides you the administrative options for managing all the parts of your hosting account and can be used for the management of web hosting and making your users easier to perform common web hosting account management tasks. DirectAdmin automates the tasks for creating separate packages and defining your customized rules so that the web servers can be easily shared and give web site owners a way to quickly set-up and manage their web sites.

The DirectAdmin control panel is very low cost and has become one of the most popular web hosting control panel in use today that provided every feature that you would like to set up on your web site with shared hosting.

Preparing Servers

In this article we going to show you the complete installation steps for DirectAmin Web Hosting control Panel on CentOS 6 and CentOS 7 servers.

1) Hostname Setup

Let’s prepare your CentOS server with basic parameters by configuring its proper Host names and IP address. To configure the basic server parameters, login to your server using the root or sudo credentials and configure your host name using below commands.

CentOS 6

# vi /etc/sysconfig/network
HOSTNAME=cantos-6

# vi /etc/hosts
72.25.10.175 centos-6 centos-6.linoxide.com

CentOS 7

# Hostnamectl set-hostname centos-7

# vi /etc/hosts
72.25.10.173 centos-7 centos-7.linoxide.com

2) Firewall Settings

After host name setup configure your firewall and SELinux to permissive mode so that you won’t get any issue during your installation setup but keep a note that enable it back and allow only your required ports in firewall if you are working on production environment.

CentOS 6

# Service iptables start

# vi /etc/sysconfig/selinux
SELINUX=permissive

CentOS 7

# systemctl start firewalls

# setenforce 0

3) System Update

Now run the following command to update your CentOS 6/7 servers with latest patches and updates.

# yum update

You asked to press Y for Yes and N for No to exit from the update, so press “Y” key and hit enter to start installing missing packages and their updates.

4) Installing Packages

Before starting the DirectAdmin installation setup, we will be installing few packages that must be installed on your CentOS 6 or 7 server.

Let’s run the below command to install some dependent packages on your CentOS server.

CentOS 6

# yum install wget zip unzip gcc gcc-c++ flex bison quota make perl bind bind-libs bind-utils openssl openssl-devel libaio libcom_err-devel libcurl-devel gd zlib-devel libcap-devel cronie bzip2 autoconf automake libtool which patch mailx cyrus-sasl-devel perl-ExtUtils-Embed db4-devel

After successful execution of above command you will be asked whether to proceed for the installation of these packages including their dependencies and updates. So, press “Y” key to proceed the installation.

CentOS 7

In CentOS 7, we need to install the following dependencies for with addition to some general packages installation as shown below.

# yum install wget unzip psmisc net-tools libdb-devel perl-DBI systemd-devel

Downloading DirectAdmin

To download the latest installation script for DirectAdmin we will be using the following command on CentOS 6/7 servers as shown.

# wget http://www.directadmin.com/setup.sh

Assign the executable permissions to the downloaded script by using the below command.

# chmod 755 setup.sh

Now you can see by list your current directory that it should have the proper executable permissions.

Starting DirectAdmin Installation:

To start installation of DirectAdmin on CentOS 6/7, let’s point to installation script and execute it within your current direct directory where you have downloaded then press “Y” key to install the required pre installation packages as shown.

Conclusion

In this article you have learned about installation of DirectAdmin on CentOS 6 and 7 server. DirectAdmin is one the best alternative to WHM-cPanel and its quite cheap and fairly easily to setup. Thank you for reading this article we hope you find it much helpful. Don’t forget to leave your valuable comments.

Hello Everybody! Welcome to our today’s article on one the most widely used, free of cost and Open Source Munin Network Resource Monitoring System. Its a perl software application can help you monitoring your each and every asset that keeps record of it and sends you the critical alerts of services for your servers, switches, applications, and any any other devices connected to your network whether its your computers, network, storage or the whole IT infrastructure. It shows all the information in graphs through a web interface that emphasis on plug and play capabilities.

Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for data, then stores the data in RRD files to updates the graphs if needed. So, after completing its installation a high number of monitoring plugins will be playing with no more effort.

Prerequisites

Your systems hardware resources depends upon your own requirements while in this article we will be using the following system resource for Munin installation on CentOS 7.

Munin installation setup requires the basic web server packages to be installed on the server. So, after basic networking setup configure your hostname, IP address and firewall settings by keeping SELinux into permissive mode.

Then start installing packages by update your system first and enabling EPEL repository on it using below commands.

# yum install epel-release
# rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

# yum update

You will be asked to press “Y” key and hit Enter to proceed for installing all required updates. Once the updates are successfully installed on your system then proceed to the installation of Apache Web server.

Apache Web Setup

To setup your Apache web server, we need to start by installing its package using the below ‘yum’ command.

# yum install httpd

Upon completion of packages installation, start and enable its service and check that its active and enabled using the following commands respectively.

# systemctl enable httpd
# systemctl start httpd
# systemctl status httpd

Installing Munin

We can install Munin and Munin Node using the below ‘yum’ command through its available repository on CentOS 7 as shown.

# yum install munin munin-node

Hit “Y” plus Enter key to start installation of Munin and Munin Noe including a large number its required dependencies.

Once the installation is complete, start its service and enable it at auto start during reboot by using the following commands.

Munin Configurations

Now configure Munin by open its default configuration using any editor as used in below command.

# vim /etc/munin/munin.conf

# a simple host tree, change localhost with your FQDN.

[localhost]
address 127.0.0.1
use_node_name yes
:wq!

After saving the Munin configuration file, Open its apache virtual host configuration file to add access permissions to your network.

# vim /etc/httpd/conf.d/munin.conf

After saving the configuration file changes , restart apache web server service using command below.

# systemctl restart httpd

Now we are going to add a new user and password to the /etc/munin/munin-htpasswd file as the Munin statistics are protected with a username and password, so we need to setup the basic Apache Authentication.

# htpasswd -c /etc/munin/munin-htpasswd admin

This will add a new user with the name “admin” and asks for the new password as shown.

# vi /etc/munin/munin-node.conf

host_name munin.linoxide.com

Save and close the file and restart munin-node services and access the following link by mentioning your FQDN or IP from the client which is in your network that was allowed in configuration file.

http://your_servers_IP/munin

Welcome to Munin Web Console

Here is the Munin dashboard, now you can check the graphs of your required servers.

We can customize Munin dashboard by adding different available plugins and add multiple node to it. While using its web console we have options to create multiple groups and categories according to the required group of services.

You can check and see the status of your critical service by opening its graph from the Munin web console that will show you the current and past data from its maintained hostory as shown in below image.

Conclusion

Munin installation has been setup. We hope you have enjoyed reading this article. The installation of Munin is quite simple, now simply add the client node and start monitoring your whole IT infrastructure using this awesome tool without paying any charges. Now enjoy using Munin on your environment and feel free to share your thoughts or suggestions in comments section.

This time we are going to talk about the Internet Relay Chat, or simply IRC. In the first part of this article we will review this protocol, how to use Irssi or XChat to connect on Freenode and other IRC networks,enter on channels and talk to people. After that, you will see how to start your own IRC service with UnrealIRCd.

• Basic IRC commands
• Serving IRC with UnrealIRCd

Introduction

You may remember the IRC chats, when there was no such thing as Facebook Google+ or LinkedIn and our social networks were IRC chat channels. Today we have a lot of alternatives to talk to someone on the internet, along with the social networks we have many popular messaging services, such as Whatsapp, Skype, Hangouts and so on.

However, despite IRC is not the main communication program on the internet, it is still alive and a great tool. It is a lightweight, widely deployed and  standardized protocol, originally created on 1988 by BBS users as a replacement and improvement for the talk program and that by its characteristics, saw the birth and death of many other messaging systems.

Connecting on IRC

To connect to an IRC network, you will need a client software. Here are some good clients for Linux.

Irssi

Irssi is a curses based IRC client, it is pretty great, customizable, allows the use of scripts and dismiss the need of a X server.

Install

yum install irssi

Connect to a network with the -c flag,

irssi -c irc.freenode.org

To switch between Irssi windows can be a little tricky at the first time,  you can use [Ctrl+n] to go to next window and [Ctrl+p] for the previous. the /window command.

/window [ next | previous ]

Use the list parameter to display a list with the open windows

/window list

You can then jump to the listed window number with [Alt+#], where # is the window number between 1-9. Another way to do this is with the goto parameter

/window goto [1-9]

You can also find good tips on how to use Irssi on quadpoint website.

XChat

XChat simplify the process for new comers by giving you point and click options to commands and most actions.

You can install XChat with yum

yum install xchat

Connect to IRC networks, using the dialog presented to you when you just start XChat, also accessible from  menu XChat->Network List [Ctrl+s]

As you sucessfully connect to the network, you can select one of the options to join to channels. You can also use the menu Server->List of Channels.

Basic IRC commands

Now you have a client ,here are some commands that you can use on IRC. When you first connect on a network, you will be given a nickname based on your system login by the client, and to change your nickname to Tuxman for instance, try this.

/nick Tuxman

With a new, you may want to enter on a channel. To list channels related to development try

/list #devel*

Once you find the channel you are interested on, try to join with /join #channelname.

/join #linux

OK, you are on a channel, you can start talking now, to know who is on the channel, do this with names

/names

Maybe you want to know more about who is someone on the network, try whois.

/whois MrRobot

Want to a chat window with someone? query.

/query MrRobot

Register you nick

You don’t need to create an account to chat on IRC networks. However, if you want to prevent your nickname of being be used by someone else, you must register you nickname on the network. This will also give you access to resources that require registered nicknames, such as cloaking and access to more channels.

Let’s suppose that you want to register the Tuxman nickname on Freenode. Ask the NickServ to REGISTER your nickname

/msg NickServ REGISTER password me@email.com

After that you must get your verification code that was sent to the email you provided and send it to NickServ

/msg NickServ VERIFY REGISTER nickname verifycode

You have registered your nickname, now you can identify yourself to the network

/msg NickServ IDENTIFY password

Connect and identify at Irssi startup with -n and -w flags.

irssi -c irc.freenode.net -n nickname -w password

You should also change your password from time to time, use the following command

/msg nickserv set password newpassword

Installing UnrealIRCd

Among other Ircd implementations there is the UnrealIRCd. It is fully featured, modular and highly documented, also the most implemented IRC server nowadays, corresponding to more than 50% of the currently running IRC servers.

Extra Requirements

Here is some requirements to get best of your UnrealIRCd, despite it is not required, it is strongly recommended as you will see.

Ntp – You must have correct time and date, ntp is your best choice to maintain time and date correct.

Install ntp

yum install ntp

Enable ntpd

chkconfig ntpd on

OpenSSL – This is also optional,  this will be used if you want SSL/TLS support.

yum install openssl

Zlib – This will let you to compress the network packets and reduce the load over the links.

yum install zlib

Get UnrealIRCd

Download Unrealircd.

wget –no-check-certificate https://www.unrealircd.org/downloads/Unreal3.2.10.5.tar.gz

Extact the tarball

tar zxvf Unreal3.2.10.5.tar.gz

Enter the sources tree

cd Unreal*

Enable chroot irc user and irc group (recommended)

This step is optional but strongly recommended as it will allow you to drop superuser rights and run UnreadIRCd under an unprivileged user account, inside a chrooted environment, and thus will make the whole setup much safer.

To do this you must edit include/config.h file within the sources directory.

Chroot environment feature is defined by the following directive

/* #define CHROOTDIR    */

Define the IRC_USER constant

/* #define IRC_USER  “<user name>” */

Define the IRC_GROUP constant

/* #define IRC_GROUP “<group name>” */

Create group for ircd

groupadd ircd

Create ircd user and add it to the ircd group.

useradd ircd -s /bin/false -g ircd

Set the password for the ircd user to make sure no one can enter.

passwd ircd

Configure the build

At this point you follow the questions on the screen,  and you can use default settings most of then, however, I advice you to answer Yes when asked to enable ssl support.

./config

Build the sources

make

Install files

make install

If you enabled the ircd user, group and chroot features, you should now change the ownership of UnrealIRCd directory.

chown -R ircd:ircd /home/ircd/UnrealIRCd

Configure

It is time to make your IRC daemon work. For this edit the unrealircd.conf, the configuration file for UnrealIRCd. You can find the well documented file doc/sample.conf under your UnrealIRCD directory tree, it may help you in your journey. I created this working snippets with a brief description.

me – This block sets some basic server settings, name, basic info and the numeric value that must be unique across server on the same network.

me {

name “irc.localhost”;
info “My Server”;
numeric 1;

};

admin –  Here you set who is the server administrator, its name, nickname and email.

admin {

“George Jedi”; /* Name */
“geroge”;/* Nick Name */
“george@heaven.net”; /* Email */

};

class clients/servers – This sets how clients and other servers are handled by the our server respectively. ping frequency, maximum of clients connections, frequency of reconnection tries, receive and send queues.

class clients {

pingfreq 90;
maxclients 500;
sendq 100000;
recvq 8000;

};’

class servers {

pingfreq 90;
maxclients 10; /* Max servers we can have linked at a time */
sendq 1000000;
connfreq 100; /* How many seconds between each connection attempt */

};

allow – Define who can connect to the server and how. First block allows user connections from any IP or hostname and limits the connections to 5 per IP. Second block allows only one authenticated connection to people from ugly.people.com

allow {

ip *;
hostname *;
class clients;
maxperip 5;

};

allow {

ip *@*;
hostname *@*.ugly.people.com;
class clients;
password “jayajaya”;
maxperip 1;

};

listen – Which ports to listen for connections. On the block we are listening at port 6697 for user clients connecting over secure socket layer (SSL). Note also the line simple statement for plaintext connections at port 6667

listen *:6697 {

options {

ssl;
clientsonly;

};

};
#listen *:8067;
listen *:6667;
#listen *:6660-6669;

oper – Operator attributes, in this example we use an operator nicknamed george that can connect from anywhere with the “fuba” password

oper george {
class clients;
from {
userhost *@*;
};

password “fuba”;
flags {

netadmin;
can_gkline;
can_kline;
can_unkline;
can_gzline;
can_zline;
can_restart;
can_die;
can_rehash;
global;

};

swhois “Example of a whois mask”;
snomask cFfkoSsqNG;

};

loadmodule – Loads modules, these are the minimum recommended

loadmodule “modules/commands.so”;
loadmodule “modules/cloak.so”;

log – How log files will be written, on the example we log events flagged as errors, kills and so

log ircd.log {

maxsize 5MB;
flags {

errors;
kills;
oper;
tkl;

};

};

set – You may set many other things here, in our example we have a network at domain gaia.net called gaianet, that connect people to the #welcome channel, we set 3 different alphanumeric cloak keys, set the hosts on the network, create a #help  channel and other options that are detailed on nrealircd.org.

set {

kline-address my@email.address;
auto-join #welcome;
op

options {

hide-ulines;

};

maxchannelsperuser 10;
services-server         “services.gaia.net”;
default-server              “localhost”;
network-name                “gaianet”;
help-channel                “#help”;
hiddenhost-prefix           “gaia”;

cloak-keys {

“aoAr1O6fh3Q6w4Hnl3J7hVz4Zb7x4YwpW”;
“andaoAr1HnR6gl3sJ7uhVzO6fh3Q6w4oN3″;
“a2Ja2JO6fh3Q6w4oNs7O6fh3Q6w4oN3s7″;

};

hosts {

local           “locop.gaia.net”;
global          “ircop.gaia.net”;
coadmin         “coadmin.gaia.net”;
admin           “admin.gaia.net”;
servicesadmin   “csops.gaia.net”;
netadmin        “netadmin.gaia.net”;
host-on-oper-up “no”;

};

};

Start UnrealIRCd

With all things in place, you can start your IRC daemon now.  Add the following command on rc.local to start UnrealIRCd when your system starts.

/home/ircd/UnrealIRCd/unreal start

It should run with no problems, however if face any problem during the startup, read the error messages on the terminal and also on the ircd.log file to figure out what is wrong.

Conclusion

You are done for now, your client and server should be running now, you can talk to people worldwide using some of the global networks or using your own network. However, it is a good idea to learn more on the IRC protocol, how to manage networks, channels and users, etc. The following documents should help you.

RFC documents

The following RFC defines the standards for the IRC protocol. You should read this before you can get best of IRC.

RFC-1459, RFC-2810, RFC-2811, RFC-2812, RFC-2813, RFC-7194

UnrealIRCd support and docs

Refer official documentation of UnrealIRCd to acquire more information. It contains all details that are not described on this document. You can also get help from IRC by connecting on irc.unrealircd.org:6667 on the #unreal-support channel. Thanks for reading!

Wine (Wine Is Not an Emulator)) is a free and open source compatibility layer software application for the implementation of Windows based applications to run on Linux. Different applications have their own dependencies to run on any operating system. Windows programs won’t run on Linux and Linux programs won’t run on the Windows applications because both are the different operating operating systems developed in their own languages. So, in order to run Windows based applications on UNIX like operating system we need an intermediate application called WINE to be installed on Linux. Using WINE whenever a Windows based program tries to perform a function that Linux doesn’t normally understand, it will translate that program’s instruction into one supported by the system.

There are multiple features of using WINE like on the thin clients by simply installing Wine on a Linux server and access from any X Windows terminal by make existing Windows applications available on the Web by using VNC and its Java client.

1) Prerequisites

To install the latest version of Wine 1.8 on your Ubuntu 15 and CentOS 7 operating system, you need to complete the basic OS requirements before moving to the installation setup.

First of all open the command line terminal from the the drop down ‘Applications’ from your Ubuntu 15 or CentOS 7 desktop menu and run the commands below using root privileges to update your operating system with base system and security update.

On Ubuntu:

#apt-get update

On CentOS:

#yum install update

2) Download Wine 1.8 Source

You can download latest package 1.8 version of Wine to download.

You can directly download it on your system using the ‘wget’ command by copying the source link address by using the command below that would be same for both Ubuntu and CentOS systems.

# wget http://dl.winehq.org/wine/source/1.8/wine-1.8.tar.bz2

3) Extract the Archive

Change your directory to the extracted folder of Wine and then configure the source package by running the below command.

# tar -xvjf wine-1.8.tar.bz2

4) Compiling Wine 1.8

You need to enable 32 bit architecture in your 64 bit operating system for installing 32 Bit supporting packages. So, run the below commands as per your requirements.

For 32 Bit:

# ./configure

For 64 Bit:

# ./configure –enable-win64

You might get few warnings about some missing libraries that you can install on your Desktop system upon requirements and then proceed to with the compilation process by using the below command in your system.

# make

Modify the SELINUX parameter to disabled and reboot the server.

Installation steps followed for installing cPanel 11.52 on CentOS 7

Before installation make sure the server meets all the pre-requisites.

1. Set hostname to a fully qualified domain

This is how we set the hostname for the server to a fully qualified domain name “server1.centos7-test.com” and confirm the hostname status once it is done.

root@server1 [~]# hostnamectl set-hostname server1.centos7-test.com –static
root@server1 [~]# hostnamectl status
Static hostname: server1.centos7-test.com
Icon name: computer-vm
Chassis: vm
Machine ID: 72863e389b584a4dab36fae7f3bffda2
Boot ID: 8bd4f714d7ba4ebf9d53f059d0a1fe8b
Virtualization: xen
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 4.1.5-x86_64-linode61
Architecture: x86-64
root@server1 [~]#

2. Check for the IP addr, subnet addr and gateway

Make sure we have a static IP with a proper subnet mask and default gateway. In this case our IP address is 45.79.183.73 with a proper subnet mask and gateway.

root@server1 [~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 45.79.183.73 netmask 255.255.255.0 broadcast 45.79.183.255

inet6 2600:3c03::f03c:91ff:fef1:78d9 prefixlen 64 scopeid 0x0<global>
ether f2:3c:91:f1:78:d9 txqueuelen 1000 (Ethernet)
RX packets 38095 bytes 13241381 (12.6 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 41505 bytes 45527241 (43.4 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

3. Check the OS, disk usage and RAM usage for the server

Our server is installed with CentOS 7.2, having a disk space of 20GB and around 1GB RAM. Please see the results of the hardware checks below:

OS version check:

#cat/etc/redhat-release

root@server1 [~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
root@server1 [~]#

Disk usage check:

#df-h

root@server1 [~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 20G 5.9G 14G 31% /
devtmpfs 492M 0 492M 0% /dev
tmpfs 494M 0 494M 0% /dev/shm
tmpfs 494M 14M 480M 3% /run
tmpfs 494M 0 494M 0% /sys/fs/cgroup
/dev/loop0 662M 736K 627M 1% /tmp
tmpfs 99M 0 99M 0% /run/user/0

RAM usage check:

free -m or cat /proc/meminfo

root@server1 [~]# free -m
total used free shared buff/cache available
Mem: 987 336 275 12 375 607
Swap: 511 1 510

4. Disable Firewall

It is recommended to disable the OS firewalls before the cPanel & WHM installations. First of all we need to save the firewall rules and then stop the firewalld service. And make sure the service is disabled.

iptables-save > ~/firewall.rules
systemctl stop firewalld.service
systemctl disable firewalld.service

root@server1 [~]# systemctl status firewalld.service
● firewalld.service – firewalld – dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)

Jan 09 06:50:28 server1.centos7-test.com systemd[1]: Stopped firewalld – dynamic firewall daemon.

5. Disable Selinux

Modify the SELINUX parameter to disabled in /etc/selinux/config and reboot the server.
root@server1 [~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing – SELinux security policy is enforced.
# permissive – SELinux prints warnings instead of enforcing.
# disabled – No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted – Targeted processes are protected,
# minimum – Modification of targeted policy. Only selected processes are protected.
# mls – Multi Level Security protection.
SELINUXTYPE=targeted

5. Installation of Perl

cPanel is programmed in Perl language. Hence, we need to install Perl prior to the cPanel installation if it isn’t installed in the server before.

yum install -y perl

6. Download/Install/Run cPanel/WHM script.

We need to download the cPanel installation script into the /home directory and run the script from there.

#cd /home
#curl -o latest -L https://securedownloads.cpanel.net/latest
#sh latest

This is how we download and install the cPanel installation script from our server’s home directory.

The script can take half an hour or more to complete the installation procedures.

7. Adding ports 2087/2086 to the firewalld service

After completing the installation procedures, we need to ensure that our server allows the required service ports in the firewall.

[root@server1 zones]# firewall-cmd –zone=public –add-port=2087/udp
success
[root@server1 zones]# firewall-cmd –zone=public –add-port=2086/udp
success
[root@server1 zones]# firewall-cmd –zone=public –add-port=2086/tcp
success
[root@server1 zones]# firewall-cmd –zone=public –add-port=2087/tcp

[root@server1 zones]#firewall-cmd –reload

If your server has enough resources, then it is always advised to disable the OS firewall and configure CSF/APF to ensure better security and allow all required cPanel service ports by default. I would recommend to go with CSF for a cPanel server.

CSF Installation steps:

 wget http://configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf & ./install.cpanel.sh

Access the WHM via the URL

You can access WHM using the URL https://server-hostname:2087 or http://server-hostname:2086

After accessing the URL mentioned above, you can put your username as root and its password to login.

Read through the terms and conditions & accept the license agreement.

Now you can do your initial configuration steps one by one as below:

1. Setup Networking
2. Setup IP address
3. Nameservers
4. Services
5. Setup quotas

Visit http://go.cpanel.net/whminit for more information about first-time configuration of your server.

Now you will have your WHM ready to use!!!

I believe this article will be a great help for you guys! Thank you for referring to this. I would appreciate your valuable comments for further improvements.

Hi, welcome to our today’s article on Apache ServiceMix. Let me give you an overview of what ServiceMix is and what you can do with it. Apache ServiceMix is a runtime container for service-oriented architecture components, web services or legacy system connectivity services. Apache ServiceMix is an enterprise-class open-source distributed enterprise service bus (ESB) based on the SOA model released under the Apache license. It is one of the most mature, open-source implementations of an enterprise service bus and an Apache top-level project. Apache ServiceMix provides an OSGi container in which we can run, configure and manage Camel and ActiveMQ instances and you can explore the other services that it can provide.

So, in the mean time, we’ll be showing thine stall ServiceMix on CentOS 7 machine to deploy some basic integration routes and extend the container with some additional features.

System Requirements

Before starting the installation, we need to prepare our CentOS 7 server with some basic requirements. Atleast 200 MB of free disk space is required for the Apache, Karaf and few other binary distributions.

Let’s connect to your server using the sudo or root user credentials and perform the following tasks,

OS Update

Run the command as given below to update your Operating system with latest updates and missing patches.

# yum update

Java Setup

For running Apache ServiceMix itself, you’ll need Java Runtime Environment (JRE) 1.6.x (Java 6) or greater. Make sure that the JAVA_HOME environment variable must be set to the directory where the Java runtime is installed.

You check the installed version of Java and current settings of your JAVA_HOME and PATH variables using the below commands.

[root@servicemix ~]# java -version
java version “1.7.0_91”

[root@servicemix ~]# echo $JAVA_HOME
/usr/lib/jvm/jre

[root@servicemix ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

Apache Maven

Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project’s build, reporting and documentation from a central piece of information. Run the below command get it install on your server before installing Apache ServiceMix.

# ]# wget http://www.eu.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz

Now extract this to the ‘/usr/local/’ directory using the below command.

# tar -zxvf apache-maven-3.3.9-bin.tar.gz -C /usr/local/

Now change directory to ‘/usr/local/’ folder and create a soft link with below command.

#cd /usr/local/

# ln -s apache-maven-3.3.9 maven

Now we will setup the Maven path system-wide by creating a new file and adding the parameters in as shown below.

# vim /etc/profile.d/maven.sh
export M2_HOME=/usr/local/maven
export PATH=${M2_HOME}/bin:${PATH}

After saving file you have to logout and then login back to implement environment variables. Then to verify successful installation of maven, check the version of maven by using the below command.

# mvn -version

Download Apache ServiceMix

After setting up the Java, you need to download the Apache ServiceMix by choosing the required package.

Copy the source link address and download it using the wget command in your server.

]# wget http://archive.apache.org/dist/servicemix/servicemix-4/4.5.3/apache-servicemix-4.5.3.tar.gz

Use below command to extract the package.

# tar -zxvf apache-servicemix-4.5.3.tar.gz

Installing Apache ServiceMix

Change your directory to the ‘bin’ directory of your extracted package and execute the the following command to start installation of ServiceMix as shown below.

[root@servicemix ~]# cd apache-servicemix-4.5.3/bin/
[root@servicemix bin]# ./servicemix

Using Apache ServiceMix Console

We have successfully installed and started Apache ServiceMix. Now we are going to show you that how you can manage your ServiceMix instance, add and remove bundles and install optional features.

Let run the following command to get a list of all bundles currently installed on your server.

karaf@root> osgi:list

If you’re looking for something specific in the list, you can use unix-like pipes and utilities to help you. Just for example run the below command to see all Apache related bundles in the list.

karaf@root> osgi:list | grep Apache

Many of the applications you write will have some form of log output. To look at the message in the log file, you can us the log:diplay command.

karaf@root> log:display

karaf@root> log:display-exception

Optional Features

You can open the list of features using ‘features:list’ command. The overview shows you whether or not the feature is currently installed, the version and the name of the feature as shown below.

karaf@root> features:list

To get the web console installed in ServiceMix, install the feature from your console using the command as shown below.

karaf@root> features:install webconsole

Now verify that the feature is marked installed in the overview by executing the below command to grep the webconsole.

karaf@root> features:install webconsole

Now you will be able to point your browser to http://localhost:8181/system/console and login with user ‘smx’ and password ‘smx’ to access the web console.

From the webconsole, now you can start and stop bundles, configure settings, install optional features or view system information all from your web console as shown below.

Conclusion

At the end of this article we have learned the one of the most mature, open-source implementations of an enterprise service bus and an Apache top-level project that is Apache ServiceMix. ServiceMix for sure is not the first choice for application development, in terms of desktop software. But if you have to deal with more complex environments, where different applications are involved and need to interact with each other, an enterprise service bus can alleviate the burden of dealing with such systems to a great extent.

dotProject is a free and open source web-based multi-user and multi-language project management application which is designed to provide project layout and control functions. It aims to provide the project manager with a web based efficient tool for managing tasks, schedules, communication and sharing easily. dotProject has a wide range of application and environment from small offices to big companies, government departments, schools and more. This project is completely managed, maintained, developed and supported by a volunteer group and by the users themselves. In this tutorial, we’ll learn how we can setup dotProject in our machine running CentOS 7 linux distribution.

Installing LAMP Stack

First of all, we’ll need to install a complete LAMP Stack in our CentOS 7 machine. A LAMP stack is the combination of Apache Web Server, MySQL/MariaDB Database server and PHP modules installed and configured together in a linux machine. In order to setup, we’ll need to run the following yum command as yum is the default package manager in CentOS 7.

# yum update
# yum install httpd mariadb-server mariadb php php-gd php-mysql php-curl php-ldap php-xsl php-xml php-cli php-mbstring php-pear unzip

Configuring MariaDB server

At first, as we haven’t set any root password for our MariaDB server, we’ll need to configure a root password for it. And after its done, we’ll move forward towards the creation of a database user and a database so that dotProject can be used to store its data. To configure MariaDB, we’ll first need to start our MariaDB server by running the following command.

# systemctl start mariadb

After done, we’ll configure MariaDB and assign a root password, we’ll need to run the following command.

# mysql_secure_installation

This will ask us to enter the password for root but as we haven’t set any password before and its our first time we’ve installed mariadb, we’ll simply press enter and go further. Then, we’ll be asked to set root password, here we’ll hit Y and enter our password for root of MariaDB. Then, we’ll simply hit enter to set the default values for the further configurations.
….
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on…
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
… Success!
…
installation should now be secure.
Thanks for using MariaDB!

Creating a MariaDB Database

Next, we’ll login to the MariaDB command prompt as root. Here, we’ll need to enter the password of the MariaDB root account that we had set above.

# mysql -u root -p

After we’re logged in into the mariadb command prompt, we’ll gonna create the database.

> CREATE DATABASE dotprojectdb;
> CREATE USER ‘dotprojectuser’@’localhost’ IDENTIFIED BY ‘Pa$$worD’;
> GRANT ALL PRIVILEGES ON dotprojectdb.* TO ‘dotprojectuser’@’localhost’;
> FLUSH PRIVILEGES;
> EXIT;

Finally, we’ve successfully created a database named dotprojectdb with username dotprojectuser and password as Pa$$worD .

Note: It is strongly recommended to replace the above variables as your desire for the security issue.

Setting PHP configuration

Then, we’ll go for configuring some settings in our PHP configuration which is located inside /etc/php.ini file. Here, we’ll need to open the file using a text editor and edit it.

# nano /etc/php.ini

Once its opened using the text editor, we’ll need to append the file with the configurations shown below.

memory_limit 128M
register_globals = Off
session.auto_start = 1
session.use_trans_sid = 0
date.timezone =America/New_York

Configuring Apache Web Server

In our CentOS machine, we’ll create a file named dotproject.conf under /etc/httpd/conf.d/ directory using a text editor.

# nano /etc/httpd/conf.d/dotproject.conf

Then, we’ll gonna add the following lines of configuration into the file.

<VirtualHost *:80>
ServerAdmin info@dotproject.linoxide.com
DocumentRoot /var/www/dotproject/
ServerName dotproject.linoxide.com
ServerAlias www.dotproject.linoxide.com
<Directory /var/www/dotproject/>
Options FollowSymLinks
AllowOverride All
</Directory>
ErrorLog /var/log/httpd/dotproject.linoxide.com-error_log
CustomLog /var/log/httpd/dotproject.linoxide.com-access_log common
</VirtualHost>

Once done, we’ll simply save the file and exit the editor.

Enabling Services

Now, we’ll gonna restart our Apache web server and MariaDB database server by executing the following systemctl command.

# systemctl restart httpd mariadb

Then, we’ll enable them to start automatically in every system boot.

# systemctl enable httpd mariadb

Downloading DotProject

We’ll now download the latest release of DotProject ie version 2.1.8 during the time of writing this article. We can download the latest release from the official sourceforge download page but as we’re gonna download it via console or terminal, we’ll simply get the link from the sourcefoge site and download it using the following wget command.

# cd /tmp
# wget http://downloads.sourceforge.net/project/dotproject/dotproject/dotProject%20Version%202.1.8/dotproject-2.1.8.tar.gz

–2016-01-19 14:49:08– http://downloads.sourceforge.net/project/dotproject/dotproject/dotProject%20Version%202.1.8/dotproject-2.1.8.tar.gz

2016-01-19 14:49:11 (2.39 MB/s) – ‘dotproject-2.1.8.tar.gz’ saved [4529234/4529234]

Once the download is completed, we’ll simply extract the tarball by running the following tar command.

# tar -xzf dotproject-2.1.8.tar.gz

We’ll then move the extracted files and directories to /var/www/dotproject/ directory as we have defined in the above apache configuration.

# mv dotproject /var/www/dotproject

Fixing Ownership

After moving the files and directories, we’ll now need to change the ownership of the directory to apache user so that apache process owner can have full read/write access over the dotproject directory.

# cd /var/www/dotproject/
# sudo chown -R apache: dotproject/

Allowing Firewall

To expose our dotProject site on the internet or inside the same network, we’ll need to allow port 80 from the firewall program. As CentOS 7 is shipped with systemd as the default init system and we’ll have firewalld installed as a firewall solution. To allow port 80 or http service, we’ll need to run the following commands.

# firewall-cmd –permanent –add-service=http
# firewall-cmd –reload

Web Installation

We’ll now go for the web based installation of dotProject. To do so, we’ll need to point our web browser to our server’s ip address or domain name as http://ip-address/ or http://domain.com/ according to the configuration. Here, in this tutorial, we’ll gonna point the url of our web browser to http://dotproject.linoxide.com/ and start the installation process as shown below.

In the start page, we’ll see that all the dependencies and settings required for the installation of dotProject has been successfully installed and configure. To start the installation, we’ll need to click on the button “Start Installation“. After clicking on that, we’ll see a page where we’ll be asked to enter the required information for logging into the database server.

Here, as we’re hosting the database server in the same server where we’re installing dotProject, we’ll assign Database Host Name as localhost, then, we’ll simply enter the Database name, username and password that we had assigned in the above step while creating the database. Once done, we’ll click on “install db and write cfg” button which will setup the database and creates a configuration file named config.php under /var/www/dotproject/includes/ directory.

Once done, we’ll see the log generated by the installer and green notifications that our database installation and config file creation has been done successfully. Then, we’ll click on “Login and Configure the dotProject System Environment” link which will ask us the login credentials required for accessing the Admin panel. The default username and password for a fresh installation of dotProject is admin and passwd respectively.

After we’ve logged in, we’ll see the following page as our dotProject Administration Panel. It is strongly recommended to change the password of administrator as soon as the first login is made.

To change the password of the admin user, we’ll need to goto User Management page by navigating to User Admin in the navigation bar. Then, we’ll need to select admin as the user and click on change password link which will popup another small window where we’ll need to enter our old password and new password to be kept.

Conclusion

dotProject has been finally setup and configured successfully in our machine running CentOS 7. It is an awesome web based project management framework that includes modules for companies, projects, tasks (with Gantt charts), forums, files, calendar, contacts, helpdesk, multi-language support, module permissions and themes with good time tracking feature. If you have any questions, suggestions, feedback please write them in the comment box below so that we can improve or update our contents.
