A subdomain is a second website, with its own unique content, but there is no new domain name. Instead, you use an existing domain name and change the www to another name. The subdomain name looks like info.domain.com.
Here are the steps to create sub-domain.
Step1: Login to the cPanel and click on Subdomains icon under Domains.
Step 2: Enter the subdomain name and click on “create”. I have entered the subdomain name as test.
Step 3: Once the subdomain is created, you can see it under subdomains list.
Step 4: A folder will be created for this subdomain under public_html inside File Manager. The files related to the subdomain needs to be uploaded inside this folder.
Step 5 : That’s it. Now you can browse the website using your subdomain name.
