Which CMS or blogging engine supports multiple sites?

Dont know if SO is the appropriate place to ask this question, but anyway ...

I have some sites running Wordpress and maintaining/managing them is a pain. Is there any CMS or blogging platform out there th开发者_JS百科at support multiple sites/blogs in one codebase ? I know there are some hacks for Wordpress but they are quite ugly and do not scale (i need 100-1000 blogs supported). WPMU AFAIK run with subdomains only.

Thanks in advance.

I'm fairly certain you can use WordPress MU in a sub directory versus a sub domain.

WordPress Hive is an alternative to WordPress MU. I'd imagine you're going to have to do some more research and reading before you make a decision.

WPMU will support multiple sites, but it's a bit tricky to implement on some hosts. WP 3.0 will roll in WPMU's multi-site features sometime very soon.

In the meantime, I use a WordPress plug-in called Hive to manage multiple installations. I have some sites set up as subdomains pointing to the same WordPress installation and some sites that are completely separate domains pointing to the same thing. It's a great way to use one WordPress codebase to manage multiple sites (one set of plug-in upgrades, on set of themes, etc).
