CiviCRM Community Forums (archive)

I am moving an existing Drupal 7 site to a multi-site setup. The main site, site1 let's say, was already running civicrm. Upon moving that and editing civicrm.settings.php it seems to be fine.

However, when I try to install CiviCRM on site2 it doesn't finish install, gives me the "an unexpected error occurred" but no errors in the logs or in Apache.

In other forum topics, I see people being pointed to http://wiki.civicrm.org/confluence/display/CRMDOC42/Multi+Site+Installation, but I don't think that's what I want because I am just sharing the codebase - the sites each have their own databases for their own Civi installs.

Is there any documentation on this anywhere? Any suggestions on what might be wrong or what I might need to do? Thanks!

Thanks Hershel, will try that. One question - do you recommend I do the failed install first so that on the Drupal side civi is at least turned on? Or just keep civi completely uninstalled and then migrate my clean install tables over and just turn civi on through a direct database query? Ideas on which is the "less corrupt" approach to this?

Thanks Hershel, all worked perfectly.

1) When Civicrm is upgraded, it needs its DB to be upgraded. Will it upgrade "all" civicrm DBs of the muliitsite?

You must run the upgrader on each site individually.

2) How many multi-sites can I have in 1 codebase? is there a practical limit?

This is a limit of your server resources mostly.
