Private Nameservers in WHM/cPanel

To set up private nameservers we need to have 2 IP addresses. Let us set up ns1.domain.com and ns2.domain.com

Here are the steps:

Login to whm: https://YourIP:2087

Find the navigation section on the left called Basic cPanel & WHM Setup, under Server Configuration. This is the first item on the left navigation bar. Find Nameservers section at the bottom. If you see ns1.domain.com and ns2.domain.com you can skip this step. If you don't see those name servers, specify them and press "Assign IP address" You can also do this from command line: Remove cache file:

rm /var/cpanel/nameserverips.cache

Before you make any changes to ns file you can make a backup:

cp /var/cpanel/nameserverips.yaml /var/cpanel/nameserverips.yaml.old

Open ns file:

nano /var/cpanel/nameserverips.yaml

Edit the file so that it contain your IP adresses and name servers like below:

---
ns1.domain.com:
  89.233.106.224: 1
  count: 1
  zones: domain.com
ns2.domain.com:
  46.21.145.131: 1
  count: 1
  zones: domain.com

Update name servers at the registrar.
