How to Create a Subdomain in cPanel
Log into your cPanel
Go to the Domains section and click on Subdomains.
Type in the name of the subdomain and select the domain to create it under. It will automatically create a folder for the subdomain in your public_html folder.
Click the Create button. You will then see a message stating it “has been created.”
Sometimes, it can take up to 24 hours for a new Subdomain to show up on the web, or propagate.
Congratulations, you have added your first subdomain!
