After registering a site and setting its nameservers, use the following steps to take it live.
In cPanel, go to Subdomains and add the subdomain, setting the Document Root to public_html/ . Strip the parent domain off the Document Root.
Go to File Manager and reload your public_html folder and you should see your subdomain.
Next, go to Addon Domains and add the new domain, being sure to set its Document Root to public_html/ .
Now you are ready to install WordPress. There are a number of ways to get this done. I prefer a manual install. This is simply a matter of copying in the WordPress files, creating a database, then editing the wpConfig.php to point to the files.
