Add a New Domain – cPanel

Login to cPanel.
Tutorial: login from the Client Area or the direct link.

Find the Domains section and click the Domains link.

Click the Create a New Domain button on the right.

Domain
To create a new domain, enter the new domain name. For example,example.com.
The interface automatically populates the remaining text boxes, and we recommend that you use these values. However, you can enter different values in the Document Root (File System Location) and Subdomain text boxes if you desire.
Document Root (File System Location)
Leave this option checked.
Optionally, you can specify the directory where you want the files for the domain to exist (the domain’s document root). To create this directory, deselect the Share document root with “example.com” checkbox, where example.com represents your main domain.
Click the Submit button.

If you get an error:
This domain points to an IP address that does not use the DNS servers
associated with this server. Transfer the domain to this server’s
nameservers at the domain’s registrar or update your system to recognize
the current DNS servers.
This error occurs when the domain you are adding points to a remote host not associated with the server.
Update the domain registrar to point the domain to nameservers that are already pointed at the server.
