When we talk about web hosting or want to manage one or multiple web sites through a user friendly web interface then there comes different web hosting control panels some of them are proprietary and many are open source. ISPConfig is one of the most widely used open source web hosting control panel for Linux that is designed to manage Apache, FTP, DNS, Emails and databases using its web based interface. The ISPConfig provides different levels of user access that is administrator, re seller, client and email-user.

Now we will setup its installation on CentOS 7, after following this tutorial you will have a user friendly web hosting control panel where you can easily manage your multiple domains without any cost.

Basic OS Setup

As we will be going to setup ISPConfig on CentOS 7, so before starting with installation process we will configure its basic parameters to configure its network settings, firewall rules and installation of its required dependencies.

Network Setup

Your Linux host should be configured with a proper FQDN and IP address and must have internet access to it. You can configure your local host by opening the hosts file of your system using below command.

# vim /etc/hosts ispcp

Configure Firewall

Enabling system level firewall is always been a good practice for securing your servers. In Linux CentOS 7 you can enable your firewall and open the required known ports using the below commands.

To enable and start firewall run below command.

# systemctl enable firewalld
# systemctl start firewalld

Then open the ports that will be used in ISPConfig setup using the below command.

# firewall-cmd --zone=public --add-port 22/tcp --permanent
# firewall-cmd --zone=public --add-port 443/tcp --permanent
# firewall-cmd --zone=public --add-port 80/tcp --permanent
# firewall-cmd --zone=public --add-port 8080/tcp --permanent
# firewall-zmd --zone=public --add-port 25/tcp --permanent

Setup Dependencies

Before we move forward let's update your system with latest updates and security patches and Enable the EPEL repository on our CentOS system to the require packages packages for the ISPConfig.

# yum -y install yum-priorities

To update existing packages on the system run the below command.

# yum update

Once your system is up to date, we will install the Development tools packages that will be required for the complete setup of ISPConfig. To install these packages you can run the below command.

# yum -y groupinstall 'Development Tools'

1) Installing LAMP Stack

Now run the below command to install LAMP stack packages with MariaDB, Apache, PHP , NTP and PHPMYADMIN.

# yum install ntp httpd mod_ssl mariadb-server php php-mysql php-mbstring phpmyadmin

After LAMP stack packages installation, restart mariadb services and setup its root password using below 'mysql_secure_installation'.

# systemctl start mariadb
# systemctl enable mariadb

# mysql_secure_installation

2) Installing Dovecot

You can install dovecot by issuing the following command.

# yum -y install dovecot dovecot-mysql dovecot-pigeonhole

After installation create an empty dovecot-sql.conf file and create a symbolic as shown below.

# touch /etc/dovecot/dovecot-sql.conf
# ln -s /etc/dovecot/dovecot-sql.conf /etc/dovecot-sql.conf

Now restart dovecot services and enable it at boot.

# systemctl start dovecot
# systemctl enable dovecot

3) Installing ClamAV, Amavisd-new and SpamAssassin

To install ClamAV, Amavisd and SpamAssassin, you make use of the following command, that will install all these packages in one go.

# yum -y install amavisd-new spamassassin clamav clamd clamav-update unzip bzip2 unrar perl-DBD-mysql

4) Installing Apache2 and PHP Modules

Now will install some of the mentioned modules that ISPConfig 3 allows to use mod_php, mod_fcgi/PHP5, cgi/PHP5, and suPHP on each website basis.

So, to install these modules with Apache2 you can run the below command in your ssh terminal.

# yum -y install php-ldap php-mysql php-odbc php-pear php php-devel php-gd php-imap php-xml php-xmlrpc php-pecl-apc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy curl curl-devel mod_fcgid php-cli httpd-devel php-fpm perl-libwww-perl ImageMagick libxml2 libxml2-devel python-devel

To configure your date and time format, we will open the default configuration file of PHP and configure the Data and Time zone.

# vim /etc/php.ini
date.timezone = Europe/London

After making changes in the configuration file make sure to restart Apache web services.

5) Installing PureFTPd

PureFTP is required for the transfer of files form one server to other, to install its package you can use the below command.

yum -y install pure-ftpd

6) Installing BIND

BIND is Domain name server utility in Linux, in ISPconfig to manage and configure DNS setting, you have to install these package using the commands shown below.

# yum -y install bind bind-utils

ISPConfig Installation Setup

Now get ready for the installation setup of ISPConfig. To download its installation package we will use following wget command to copy the package from the officially provided web link of ISPConfig.

# wget

Download ISPConfig

Once the package is downloaded, run the below command to unpack the package.

# tar -zxvf ISPConfig-3-stable.tar.gz

Then change the directory where its installation package is placed as shown in below image.

Installing ISPConfig

Now we will run the installation through the php program by running the following command in the terminal.

# php -q install.php

ispconfig installer

Initial configuration

Select language (en,de) [en]:

Installation mode (standard,expert) [standard]:

Full qualified hostname (FQDN) of the server, eg server1.domain.tld [ispcp]:

Database Configurations

MySQL server hostname [localhost]:

MySQL root username [root]:

MySQL root password []: *******

MySQL database to create [dbispconfig]:

MySQL charset [utf8]:

Then the system will be Generating a 4096 bit RSA private key to write a new private key to 'smtpd.key' file. After that we have to enter information that will be incorporated into certificate request.

Country Name (2 letter code) [XX]:UK
State or Province Name (full name) []:London
Locality Name (eg, city) [Default City]:Manchester
Organization Name (eg, company) [Default Company Ltd]:Linoxide
Organizational Unit Name (eg, section) []:Linux
Common Name (eg, your name or your server's hostname) []:ispcp
Email Address []

When you add above information, the system will be configured with all of its required packages as shown in the below image and then you will be asked for a secure (SSL) connection to the ISPConfig web interface.

Once you have entered the information for generating the RSA key to establish its SSL connection you will be asked to configure some extra attributes, whether to choose the default or change as per your requirements. Then it will be writing RSA key, configure DB server and restart its services to complete the ISPConfig installation setup.
