[Plugin: WordPress MU Domain Mapping] sites vs domains vs mapping vs FAQ

  • OK I hate to jump in here and ask what seems like a total noob question, I am reading all of the FAQ and forum posts I can but the more I read the more I’m confused. I’ve used WordPress for quite a while by maintaining numerous separate installations and want to move them all to a single Mu installation.

    The FAQ says:

    Does it support regular domains in addition to sub-domains?

    Sure, to MU a domain is just a domain. You can configure it to respond to any top-level domains or subdomains.

    Great, this sounds like I can just add multiple domains and it “just works”! But adding a new blog seems to force me to create a subdomain. So I go back to edit the Blog and change it to just the domain I want. (In Apache 2nd domain has same DocumentRoot).

    It appears that everything works fine, until I go to wp-admin of the second blog, then when I try to login it just keeps redirecting to wp-admin. (I cleared all cookies but still no luck).

    Then I read in the forums about the Multi-Site Plugin and the Domain Mapping Plugin, which seem to have similar but not quite the same functionality.

    All I want to do is use WordPress Mu 2.7 to host multiple blogs on multiple domains using a single installation. Can someone please explain whether I need any plugins and if so which of the above two I need?

    Do I have to have the subdomains of the “main” domain created even if I only want the alternate domains?

    I really love WordPress and am looking forward to simplifying my admin time of these sites but my head is really spinning here… many thanks in advance.

  • Probably want to ask at the MU forums, though you may get someone who can answer here.

    Hi- the MU forums is a good idea for further thoughts.

    I have one client running WPMU, and we are using the domain mapping plugin now.

    To use that plugin, the WPMU installation must be a subdomain one, not a folder installation. And yes you have to create the blog as a subdomain. Then you map the domain on top of the subdomain. Using the instructions I got from Andrea, a regular at the MU forum, after setting up the domain and mapping it to the subdomain, I then go through all the settings for that blog, replacing all references to the subdomain with the domain.

    This works fine, and I have even mapped one blog to a subdomain at the person’s individual domain. The core of MU is 100% WP. There is an admin layer over the top of it, and the table prefixes are different. But everything you have learned about WP will be of value and still relevant if you switch to MU.

    So sorry, I thought I was in the MU forums. I’ll ask over there, sorry for the noise…
