WordPress MU

I have a simple scheme in mind for running WordpressMU, but for some reason setting up the added blogs to work with top level domains eludes me.

The location of my WPMU install is "public_html/wpmu/" and is working perfectly. I can create new blogs just fine.

I have an addon domain "mydomain2.com" on my host that points to the WPMU install directory "public_html/wpmu/".

For the master site the following is set:
Domain: "mydomain1.com"
Path: "/wpmu/"
siteurl & home: "mydomain1.com/wpmu/"

No matter what settings I tried for my added blog with domain "mydomain2.com", the best it mustered was showing my home page for the domain and that was only when I set up the Path to be "/wpmu/" as well which gives a non-existing URI "mydomain2.com/wpmu/", and I could never not login to the admin section. It would either take me to my master blog home page or 404.

What is the correct way to get another blog to work with my "mydomain2.com" domain.

Thank you,

This is a common request. Basically if you install into a subdirectory, it messes up the path for subdomain creation.

Best bet is to install either at the root of your existing domain or create a subdomain off your main domain. So if your main site is at http://www.mydomain1.com create a blogs.mydomain1.com to install wpmu at. Then using the subdomain creation mode it will create site1.blogs.mydomain1.com, site2.blogs.mydomain1.com, etc.

Then if you want mydomain2.com to point to site1.blogs.mydomain1.com use donncha's WPMU Domain Mapping plugin.

My host does not support wildcards. Is their a way to handle this using sub-directory mode, or perhaps you know how to operate this scenario using addon-domains?

Not really. Also if your host isn't allowing wildcards and you do something to get around that, you;re probably in violation of your host's AUP and will probably get booted.

Best bet would be to move hosts. Really a customer service issue as most hosts will set you up with wildcards.

Are you opening the site up for public blogs or just using it for a few sites of your own?

If the later, have a look at this thread:

You need a plugin.

This one:

(which does not work on a subfolder install)
