Creating Subdomains

At this point in your BYU Domains experience, you have a website that is up and running. However, some people want to create multiple sites that appeal to different audiences or sometimes a teacher requires you to post something to a website as part of an assignment. When you want to create a separate site without registering a whole new domain, creating a subdomain is the answer.

Watch the video tutorial or continue reading for written step-by-step instructions:

The best way to explain a subdomain is looking at BYU's website: BYU's main website has a ton of different links that take you to other websites run by the university. The following pages all are subdomains of the BYU website:,,, and These pages are all run by different departments and look really different from each other, even though they technically are all still linked up to the main BYU URL.

With those examples in mind, a subdomain enables you to add on a word or two in front of your main domain name in order to create a URL that links to an entirely different designed page. Creating subdomains within your existing website is a great way to branch out and address different audiences and topics without having to drastically change your existing site.

Creating a subdomain is easy:

1. Go to the BYU Domains dashboard, scroll down to the “Domains” section and click on the icon for “Subdomains.”

2. On the Subdomains form, fill out the “Subdomain” box with a one or two word phrase. Then make sure that your domain name is selected under “Domain”. After you finish with that, the “Document Root” section will automatically populate. Make sure all the information is correct, and then click “Create.”

3. You will get a “Success” message, which means that your subdomain was created. However, your new subdomain doesn't have any CMS system installed on it. Just like when you registered your original domain, you will need to go and install a CMS system in order to put content on the subdomain.

4. In order to install Wordpress, the most popular CMS system, on your new subdomain, go back to the BYU Domains dashboard and scroll down to the “Applications” and click “WordPress.”

5. Click the top right button that says “Install.”

6. Under the “Location” section, make sure you select your correct subdomain from the dropdown menu as the place you are installing Wordpress.

7. Further down on the form, under the “Settings” section, change your username and password to something that you can remember.

8. Click the “Install” button to install WordPress onto your subdomain.

9. Now that you have WordPress installed on your subdomain, you can start designing your site and uploading content. If you need a refresher course on how to do this, please visit Making Your Domain Your Own.
