How To Add & Use Multiple Servers Via DNS Cluster Of WHM & cPanel?

While using more than one dedicated server, a DNS cluster allows you to add more servers via WHM so that your group of name servers can share records.

This enables you to physically separate the nameservers that handle the DNS requests from your cPanel and WHM dedicated servers. So that whenever a DNS change occurs on one of your main servers, it gets replicated immediately to all the other servers added in your DNS cluster.

To add the new server to the DNS cluster, simply login to your account and visit your server’s home to implement these changes:

1. Visit WHM’s DNS Cluster interface via WHM -> Home -> Clusters -> DNS Cluster
2. Click to Enable DNS Clustering
3. Click the Change button
4. Click Return to Cluster Status
5. Select the server to add to the DNS cluster
6. Add a new server to the cluster menu
7. Click Configure
8. In the Remote cPanel & WHM DNS host text box of the cPanel DNS Remote Configuration interface
9. Enter the hostname or IP address of the nameserver to add to the cluster
10. Enter the WHM username for the nameserver
11. Enter the nameserver’s API token hash or remote access key in the Remote server access hash text box
12. To automatically configure the DNS cluster on the remote server – Select Setup Reverse Trust Relationship
13. To synchronize the new server with other nameservers simply select Synchronize Zones Immediately option
14. To specify the server’s DNS role, select a setting from the DNS Role menu
15. Click the Submit button
