Is there a way to setup wordpress mu so that it is available to all sites on my server in a similar way to phpmyadmin? If there is what are the basic steps or is there a tutorial for installing it? If I am on the wrong track please point me in the right direction. Thanks.
There are several possible solutions: 1) If all these sites are your own sites, install wordpress MU in one website and then add all other domains as co-domain to this site. 2) If this are different sites and wordpress MU shall be reachable on a url like www.domain.com/wordpress/, you can try to define a global alis for the sub url /wordpress in the apache2 configuration.
