This demo assumes you've already logged in to cPanel
Now let's learn how to create a subdomain
1) Click the Sub Domains icon
2) Enter the prefix of your new subdomain here...
3) Make sure the domain name your subdomain will be associated with is selected
A directory name the same as your subdomain prefix will automatically appear... although you can change this if you want.
4) When ready, click Create
Success! A new subdomain has been created.
It's located in the public_html directory, and can also be accessed like this:www.mybiz123.net/clients
A folder called "clients" has also been created, which is where you would upload files for this subdomain.
This is the end of the tutorial. You now know how to create a subdomain in cPanel
