I've just set up WordPress 4.8.2 on Ubuntu 16.04, and configured it for Multisite using sub-domains.

I can browse to wordpress.mycompany.com/wp-admin and things work fine.

If I select Sites -> Add New Site, I am aksed for the site address and it is always xxx.wordpress.mycompany.com however I do not want 3 levels of sub-domains. I'd rather have Site1.mycompany.com and Site2.mycompany.com. Is this possible, and if so how do I achieve that? Documentation I've seen on the internet always seems to assume 4 3 levels of sub-domains.

  • No limit to create a sub-domains multisite but it's depends on server space. if your server space is not enough then not possible. Oct 11, 2017 at 11:36
  • @PatelJignesh - that doesn't answer my question.

I haven't been able to find out how to do this automatically, but you can do it manually: Go to Network Admin » Sites and then click Edit on the site whose URL you want to change.

You'll need to make sure that your DNS is set correctly.

See this answer (to a question that's pretty much the inverse of yours) for details.


Your initial setup should have been toplevel, not a subdomain. ie (www.example.com or example.com) That's where your problem is. Right now wordpress thinks your toplevel is wordpress.example.com. and then it's adding subdomains to that.
