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 -y install epel-release

Install bind:

sudo yum -y install bind bind-utils haveged vim

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

sudo vim /etc/named.conf

with below content:

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/named.run";
              severity dynamic;
      };
};
zone "." IN {
      type hint;
      file "named.ca";
};
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

Confirm the service is in running state:

$ systemctl status named.service
● named.service - Berkeley Internet Name Domain (DNS)
   Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2021-04-28 17:17:29 UTC; 9s ago
  Process: 9446 ExecStart=/usr/sbin/named -u named -c ${NAMEDCONF} $OPTIONS (code=exited, status=0/SUCCESS)
  Process: 9444 ExecStartPre=/bin/bash -c if [ ! "$DISABLE_ZONE_CHECKING" == "yes" ]; then /usr/sbin/named-checkconf -z "$NAMEDCONF"; else echo "Checking of zone files is disabled"; fi (code=exited, status=0/SUCCESS)
 Main PID: 9448 (named)
   CGroup: /system.slice/named.service
           └─9448 /usr/sbin/named -u named -c /etc/named.conf
....

Step 2: Install and Configure ISPConfig on CentOS 7

ISPConfig requires:

  • MySQL Database
  • PHP

Install MariaDB Database server

Add MariaDB YUM repository:

cat <<EOF | sudo tee /etc/yum.repos.d/MariaDB.repo
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.5/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF

Install MariaDB Server and Client packages on CentOS 7:

sudo yum -y install MariaDB-server MariaDB-client

Start and enable MariaDB service:

sudo systemctl enable --now mariadb

Secure MariaDB by running mysql_secure_installation.

$ sudo mysql_secure_installation 

Add Remi repository for installing PHP:

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

sudo yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum -y install yum-utils
sudo yum-config-manager --disable remi-php54
sudo yum-config-manager --enable remi-php74

Install PHP and required modules

Use the following commands to install PHP and its modules

sudo yum -y install php php-{devel,mysqlnd,gd,imap,ldap,pear,xml,xmlrpc,pecl-apc,mbstring,mcrypt,snmp,soap,tidy}
sudo yum -y install curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel mod_fcgid php-cli wget

Confirm PHP installation by checking the version:

$ php --version
PHP 7.4.18 (cli) (built: Apr 27 2021 14:35:46) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies

Install httpd:

sudo yum -y 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

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 https://ispconfig.org/downloads/ISPConfig-3.2.4.tar.gz

Extract the archive:

tar xfz ispconfig.tar.gz

Start installation:

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

You should get an initial screen similar to below:

--------------------------------------------------------------------------------
 _____ ___________   _____              __ _         ____

                                             |___/
