Hello, rajendrancreative

You need a fully qualified domain name as your server hostname. Run this command in order to set the hostname

hostname host.domain.net

Also please make sure to check our existing tutorial on how to install cPanel:

Hello friend!

Though this documentation is a bit older, it should be quite fine for the task. Basically, you need a fully qualified domain name as your server hostname. Check out this guide:
