How to Setup ISPConfig DNS Only on CentOS 7

ISPConfig is an open source hosting control panel developed by company ISPConfig UG for Linux. ISPConfig is licensed under BSD license. It is capable of managing multiple servers from one control panel. In this guide, I’ll show you how to set up and use ISPConfig to manage Bind DNS Server.

ISPConfig can manage below software packages and daemons:

  • HTTP: Apache2 and nginx
  • SMTP: Postfix
  • POP3/IMAP: Courier and Dovecot (1.2.x)
  • FTP: PureFTPd
  • DNS: BIND and MyDNS
  • Database: MySQL
  • Statistics: Webalizer and AWStats
  • Virtualization: OpenVZ

For a list of all services and features, check ISPconfig Features page.

Setup ISPConfig DNS Only

To have a functioning ISPConfig DNS only server, we will:

  • Install and configure Bind
  • Install and configure ISPConfig GUI

Step 1: Install and Configure Bind DNS Server

Start by installing epel-release then bind package

sudo yum install epel-release

Install bind:

sudo yum -y install bind bind-utils haveged

Once bind has been installed, backup configuration file and create a new one:

sudo mv /etc/named.conf /etc/named.conf.bak

Create a new configuration file with below content:

# cat /etc/named.con
options {
      listen-on port 53 { any; };
      listen-on-v6 port 53 { any; };
      directory       "/var/named";
      dump-file       "/var/named/data/cache_dump.db";
      statistics-file "/var/named/data/named_stats.txt";
      memstatistics-file "/var/named/data/named_mem_stats.txt";
      allow-query     { any; };
      allow-recursion {"none";};
      recursion no;
logging {
      channel default_debug {
              file "data/";
              severity dynamic;
zone "." IN {
      type hint;
      file "";
include "/etc/named.conf.local";

Create a named.conf.local then start named service

sudo touch /etc/named.conf.local
sudo systemctl enable named.service
sudo systemctl start named.service

Step 1: Install and Configure ISPConfig on CentOS 7

ISPConfig requires:

  • MySQL Database
  • PHP

To install MariaDB Server, use: Install MariaDB 10.x on CentOS 7

Add Remi repository for installing PHP:

We will install all PHP packages from the Remi repository. Add it like below

sudo yum install
sudo yum install yum-utils
sudo yum-config-manager --disable remi-php54
sudo yum-config-manager --enable remi-php72

Install PHP and required modules

Use the following commands to install PHP and its modules

sudo 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

Install httpd:

sudo yum install ntp httpd httpd-devel mod_ssl perl-DateTime-Format-HTTP perl-DateTime-Format-Builder

Set PHP timezone:

$ sudo vim /etc/php.ini
date.timezone = Africa/Nairobi

Restart httpd:

sudo systemctl restart httpd

For Nginx:

sudo yum install nginx

Install and configure ISPConfig DNS Only

As of this writing, the latest release of ISPConfig is 3.1. Install this using commands below:

cd /tmp 
wget -O ispconfig.tar.gz

Extract the archive:

tar xfz ispconfig.tar.gz

Start installation:

cd ispconfig3*/install/
php -q install.php

You should get an initial screen similar to below:

 _____ ___________   _____              __ _         ____
|_   _/  ___| ___  /  __             / _(_)       /__  
  | |  `--.| |_/ / | /  / ___  _ __ | |_ _  __ _    _/ /
  | |  `--.   __/  | |    / _ | '_ |  _| |/ _` |  |_ |
 _| |_/__/ / |     | __/ (_) | | | | | | | (_| | ___

                                              __/ |

>> Initial configuration

    Following will be a few questions for primary configuration so be careful.
    Default values are in [brackets] and can be accepted with <ENTER>.
    Tap in "quit" (without the quotes) to stop the installer.

The next two questions are about the internal ISPConfig database user and password.
It is recommended to accept the defaults which are 'ispconfig' as username and a random password.
If you use a different password, use only numbers and chars for the password.
