Is it possible to run more than one site on the same WordPress core and a set of plugins?

I want to be able to have custom plugins and themes for each site, but have a base set that is the same, to make it easier to maintain.

Do you want to have the files only once or is it okay to have sort of packages and a repository that your several sites are using? – hakre Sep 5 '10 at 8:18

Yes, it is possible.

You can setup subdomains sites like this: subdomain1.domain.com, subdomains2.domain.com.

Then, after you setup the network, use a domain mapping plugin to setup a domain name for each of them. subdomain1.domain.com becomes domain1.com, subdomain2.domain.com becomes domain2.com, etc.

There are several domain mapping plugins out there:

Maybe this WordPress MU Domain Mapping (Wordpress Plugin) is handy for that? Just like running a Multisite installation and offer Plugins in the Network.

If you're on a linux platform and you have SSH access to modify or do work inside the server, maybe creating symlink to the core or plugin would work. Just a thought though :)
