If you want to use your unique domain as nameserver and also account at the same time in Centos Web Panel, then you should be careful and read this tutorial.
1- Point your domain to your server IP, you should create child name servers under your registrars control panel.
2-If your nameservers and ip’s added to server configuration by your service provider, delete them under
CWP->DNS Functions->List DNS Zones
Find ns1.yourdomain.com.db and ns2.yourdomain.com.db
DELETE them both. Ignore any errors.
3- Again go to CWP->DNS Functions->List DNS Zones and find yourdomain.com.db
Press “Edit File” button and add below records at the bottom of the file.
ns1 14400 IN A 111.222.333.444
ns2 14400 IN A 111.222.333.444
Replace 111.222.333.444 number with YOUR SERVER IP
4- Go to Apache Settings->Rebuild Virtual Hosts
Go to Dashboard Restart Apache and BIND DNS Server
Your domain should show test page on yourdomain.com URL, and also your nameservers should catch responses and redirect to your server.
