How to Setup ISPConfig DNS Only on CentOS 7
ISPConfig is a free, open-source, powerful control panel for Linux servers that allows you to manage, monitor, and control all tasks through a web browser. It is very secure, fast, and stable, and used by many system admins to manage their servers. You can add domains, email addresses, websites, databases, and many more with ISPConfig.
ISPConfig Features
- Supports three-tier access levels, Administrator, Resellers, and Clients.
- Manage multiple servers from a single control panel.
- Supports IPv4 and IPv6.
- Supports Ubuntu, CentOS, Fedora, Debian, and OpenSuSE.
This tutorial will explain how to set up the ISPConfig control panel on CentOS 7 server.
Requirements
- A server with CentOS 7 installed.
- A root password is configured on your instance.
Getting Started
Before starting, updating your server with the latest version is recommended. You can update the server with the following command:
yum update -y
Next, you will need to set a hostname for the server. The hostname must be a fully qualified domain name. You can set the hostname of your server
hostnamectl set-hostname test.example.com
Next, you will also need to disable SELinux on your server. You can disable it by editing the following file:
nano /etc/selinux/config
Change the following lines:
SELINUX=disabled SELINUXTYPE=targeted
Save and close the file. Then, restart your system to apply these changes.
Install Apache, MariaDB and PHP
By default, the latest MariaDB version is unavailable in the CentOS default repository. So, you will need to add the MariaDB repository to your system.
You can add it with the following command:
nano /etc/yum.repos.d/MariaDB.repo
Add the following lines:
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.4/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Save and close the file. Then, install MariaDB server with the following command:
yum install mariadb-server mariadb-client
Next, you will also need to add Remi repository to install PHP. You can add it with the following command:
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum install yum-utils
Next, disable PHP5.4 and enable PHP7.2 with the following command:
yum-config-manager --disable remi-php54
yum-config-manager --enable remi-php72
Next, install PHP with all required modules by running the following command:
yum install php php-devel php-mysql php-gd php-imap php-ldap php-pear php-xml php-xmlrpc php-pecl-apc php-mbstring php-mcrypt php-snmp php-soap php-tidy curl curl-devel perl-libwww-perl imageMagick libxml2 libxml2-devel mod_fcgid php-cli wget
Once the installation has been completed, open php.ini file and change your TimeZone setting:
nano /etc/php.ini
Change the following line:
date.timezone = Asia/Kolkata
Save and close the file.
Next, install Apache webserver with the following command:
yum install ntp httpd httpd-devel mod_ssl perl-dateTime-format-HTTP perl-dateTime-format-builder
Finally, restart Apache service and enable it to start on boot time with the following command:
systemctl restart httpd
systemctl enable httpd
Install and Configure ISPConfig
First, download the latest version of ISPConfig with the following command:
wget -O ispconfig.tar.gz https://git.ispconfig.org/ispconfig/ispconfig3/repository/archive.tar.gz?ref=stable-3.1
Next, extract the downloaded file with the following command:
tar xfz ispconfig.tar.gz
Next, change the directory to ispconfig and start the installation with the following command:
cd ispconfig3*/install/
php -q install.php
You should see the following screen:
