Enabling DNS clustering with cPanel DNS

Enabling DNS clustering on each server

A DNS cluster is a number of nameservers that share records. To optimally configure your DNS cluster, you will need 2 spare servers, both preferably running cPanel DNS ONLY. You will also need at least 1 web server with cPanel/WHM installed.

You can download the cPanel DNS ONLY software here.

All machines in the cluster must be running cPanel or cPanel DNS ONLY version 11 or higher. Some features may not work with older versions of cPanel.

Enabling DNS clustering on each server

First, you will need to enable DNS clustering via each server’s WHM interface.

1. Navigate to WHM’s Configure Cluster screen.
2. Click Enable Dns Clustering.
3. Click Change.
4. Click Return to Cluster Status.

Next, you will need to specify which server(s) you wish to cluster, or share DNS information with.
You do not need to link dedicated DNS servers to each other, or link dedicated web servers to each other.
You will need to sync each web server to its DNS servers.
You should not set a DNS server to sync data back to a web server, as this will put extraneous data on the web server.
