Are you looking for help on how to setup a hostname for your VPS? If yes, then here is the step by step information for it.A. The hostname must be FQDN - Fully Qualified Domain Name
hostname is the your server’s name that you want to set. For example if you want to set it server.domain.com. Always set the hostname with the DomainName that you owns.

1. http://IP/whm edit dns zone .. select your domain

server IN A YourSeverIPHere
www.server IN A YourSeverIPHere
OR
if you are using shell then you can simply append following lines there in
# vi /var/named/domain.com.db

server IN A YourSeverIPHere
www.server IN A YourSeverIPHere

Save the file
#service named reload
#rndc reload domain.com

or
Login to shell /server as a root and fire this command the second parameter will the hostname that you want to set.
hostname server.domain.com

3. Check /etc/hosts file that it is set properly.

You need to add there
