WordPress MU

My apologies in advance if I'm asking repeated question. I looked through several candidate threads on the forum for domain mapping, etc and experimented on my own a little, but I think it's time to get some feedback from the experts.

I'm hosting 4 domains on a single 1&1 account, with each domain set up in 1&1's own Control Panel to point to ~/domainname internally.

I've been experimenting with both the subfolder and subdomain installs of WPMU 2.9.2. I'm currently using subfolders off a subdomain, so the blogs are at:
http://blogs.domain1.com/blognameXX

While I don't mind the above base URL being reachable, I'd like to set up a variety of mappings as shown below to keep the blogs separate as much as possible, so:
http://www.domainXX.com/blog -> blog1,
http://www.domainYY.com/ -> blog2, etc.

I've tried using .htaccess, the domain mapping plugin, and was on the verge of looking into CNAMEs before this post.

One of the things that's throwing me is: There's a site-wide base URL that needs to be configured, so I'm not sure how I would get multiple domains into the picture.

I'd appreciate it if someone could tell me what I'm missing, or point me to a thread somewhere that describes a solution (partial is fine).

Yes, you need the domain mapping plugin.

The part where you got lost was telling your server/web host where to send the domain requests. MU or the plugin can;t do that bit for you. ;)

On your end, point the domain to the folder where you installed MU. Not the ~/domainname folder.

MU handles it from there.

Hmn. So suppose I have WPMU installed at ~/wordpress. You're saying my domains should point there?

I can see how that's the standard use case and installation procedure if the only domain content I have was running off WP, but what if I other content hosted and only want the blog folder mapped? Ie,

http://www.domainXX.com/YYY -> ~/domainXX.com/YYY
http://www.domainXX.com/blog -> [the appropriate WPMU blog]

The blog folders in MU don't exist. point the domain to the root MU install. MU will read the request & serve up the correct blog.

If you only want the blog folder mapped, you're out of luck. Can't map folders. That's a dns thing, not a MU thing. if it was blog.domain.com? Then yeah, you can do it.

Hats off and noobie alert!

By "pointing the domain" you mean create a symlink?

That would do it.

On a little bit of a different note, in WP 3.0 RC1, I seem to be unable to see the Tools-map domain submenu. I do, however, see the Domain Mapping option under the Super Admin.

Any thoughts?

If you're on the main blog, you won;t see it under Tools. Go to a member blog.

@ andrea_r

Thank you for your advice on using the mapping plugin with 1and1. I too have been trying to get this to work with no success. Your comment about pointing the domain name in the 1and1 control panel to the "destination" folder that WPMU was installed in worked for me!

Thanks!
