Linking a domain to a subdomain with Plesk

Hello,
I know how to install a stand-alone domain on Plesk but I have no idea on how to install/assign a domain name to a sub-directory of a WP Multisite.

Ex: site1.com installed on site1.wpmultisite.com

Any help would be really appreciated.
Thank you and regards :slight_smile:

    Hello there John

    In general, you will need to add an additional domain in your Plesk for the mapped domain. This mapped domain shouldn’t be pointing (documentRoot) into a separate folder on the server, but in the same path where the WP multisite is (like /public_html/).

    So when the mapped domain is entered in a browser, it will actually point to the WP site, which will be responsible to load the proper subsite.

    In order to map the newly added domain in a subsite, you just have to log in to your WP, edit the corresponding subsite and change its site URL from site1.wpmultisite.com to site1.com.

    Hi Dimitris,

    Thank you for your response.

    I am lost :wink: I thought I had an idea now I am not too sure anymore lol.

    So the part on installing a domain the standard way is something I have no problem doing. Where I struggle right now (and I was not able to see it in the instructions) is how to add a domain on Plesk that will use the subsite as the root of the domain. I can do a redirect but this will change the url from the domain to the multisite URL (which I don’t want).

    So the only part that I need to know is how to add a domain on plesk so it will show up as the domain and not the multisite subdomain URL. I know pluggins are no longer mapping domains and I check the alias part and it doesn’t seems to be the thing to use because the subdomain is created by WP and I don’t see where a domain can be linked.

    So If you know any visual steps on how to do it with plesk I would really appreciate it.

    Thank you once again Dimitris –
    Kindest regards,
    John

    Hello John !

    Not sure if I’m getting it right too, but here’s what may be missing:

    1. As you know how to add a subdomain in Plesk the usual way (as shown on the guide shared by Dimitris), the key here is to make sure the Document root matches the directory where your multisite’s files are located (usually the same as where you have the wp-config.php file etc.).

    2. Once that is done, Plesk will route the domain to the correct multisite install. But now WordPress needs to know which site to serve.

    3. So in the Network’s wp-admin, please visit Sites >> All sites and Edit the subsite in question. You should see this screen:

    [attachments are only viewable by logged-in members]

    Here you put the domain in the Site Address (URL) field – please include the http:// or https:// and the slash / at the end.

    Once saved, WP will receive requests for the domain and will know where to route them – to which subsite.

    Hope this clears things out a bit more.

    Kind regards,
    Pawel
