How to install ISPConfig 3 on CentOS 7

First of all you must install the following

yum install net-tools

yum install telnet

yum update

yum upgrade

Disable Selinux (This must be done on each node)

sed -i 's/enforcing/disabled/g' /etc/selinux/config /etc/selinux/config

Disable firewall (firewalld) (This must be done on each node)

                                                      
systemctl disable firewalld

Once you are logged in to the server, you can type the following commands to update all of your currently installed packages to their latest available versions. After that, you’ll enable the required packages for the ISPConfig by installing the “Development Tools” bundle:

yum -y install yum-priorities

yum update

yum -y groupinstall 'Development Tools'

Install LAMP Stack

Once the system is up to date, we can continue installing the LAMP stack with Apache, MariaDB, PHP, NTP, and phpMyAdmin.

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

After the LAMP stack has been successfully installed on your server, you can use the commands below to start and enable the MariaDB service on the server.

systemctl start mariadb.service

systemctl enable mariadb.service

The next command is optional, but recommended by us. You can run this command if you want to secure your MariaDB server by disallowing remote root access, removing the test database, and creating a root password.

mysql_secure_installation

When prompted, answer the questions below by following the guide.

Enter current password for root (enter for none): Press the [Enter] key - we do not have a password currently set.

Set root password? [Y/n]: Y

New password: Enter your password

Re-enter new password: Repeat your password

Remove anonymous users? [Y/n]: Y

Disallow root login remotely? [Y/n]: Y

Remove test database and access to it? [Y/n]: Y

Reload privilege tables now? [Y/n]: Y

Restart the MariaDB server so that the changes take effect.

Install Dovecot

You can execute the following command to install Dovecot on your server:

yum -y install dovecot dovecot-mysql dovecot-pigeonhole

When the installation is complete, create a dovecot-sql.conf file using the command below, after which you’ll make a symbolic link pointing back to the file you just created:

touch /etc/dovecot/dovecot-sql.conf

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

Now use the following commands to restart and enable the Dovecot service on the server.

systemctl restart dovecot.service

systemctl enable dovecot.service

Install Amavisd-new, ClamAV, and SpamAssassin

By using the next command you will install ClamAV, Amavisd, and SpamAssassin, along with all of these additionally required packages, all in one go.

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

Install PHP and Apache2 Modules

In this step, we will install some required Apache and PHP modules, such as mod_php, mod_fcgid, php-mysql, and so on. To proceed with the installation of the modules, use the command below:

yum -y install wget yum-utils

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

yum-config-manager --enable remi-php70

Install PHP and additional extensions.

yum -y install php php-json php-mcrypt php-ldap php-xml php-bcmath php-mbstring

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

Install PureFTPd

The most popular method for transferring files from one server to another or from one place to other is through the FTP protocol. In order to use this protocol, you’ll need to install an FTP server first. We will install PureFTP server because it is simple to install and easy-to-use. To install it on your server you only need to execute the following command:

yum -y install pure-ftpd

Install BIND

BIND, or named, is one of the most commonly used Domain Name System software packages available on the Internet. In order for ISPConfig to be able to manage and configure the DNS settings, you need to install the following packages on the server:

yum -y install bind bind-utils

Install ISPConfig

After we finish all previous steps, it’s time to download and install ISPConfing 3 on the server. We will use the wget command to make a copy of the official web link on the ISPConfig website. To change the directory to /opt/ and download the ISPConfig packages, run the next two commands:

cd /opt/

wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz

Once the package has been downloaded, we’ll need to unpack it in order to use it. Unpack it with the command:

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

Then use the following command to change the directory where the install script is placed.

cd ispconfig3_install/install/

To start the installation, you need to run this command:

php -q install.php

The installation instructions are self-explanatory, with each prompt describing exactly what sort of input ISPConfig expects. Once the setup is complete, you can continue to the next step.

ISPConfig Login

Since the installation is completed, you should be able to access the ISPConfig control panel on your web browser. Open your preferred web browser and type your server’s IP address with the default configured port for ISPConfig, as shown below.

https://server_IP_address:8080/

 Enter the login credentials so that you can log in.

Upon login on the ISPConfig panel, you will see the panel dashboard, as shown in the image below.

In this article, we showed you how to install LAMP, Dovecot, Amavisd-new, ClamAV, SpamAssassin, PureFTPd, BIND, and of course, ISPConfig. Now you can continue exploring this open source control panel and check the possibilities that it offers.
