/SW/business/Drupal: Multi-Site Drupal: Trivial

First install one site, say for domain1.com, just like it was a single-domain install. Settings for the first site will automatically be placed in the sites/default directory.

Now configure Drupal for a second domain, domain2.com. Create a second MySQL database for domain2. Copy /sites/default to sites/domain2.com and edit sites/domain2.com/settings.php. In this file there is a line of this form:

$db_url = 'mysql://username:password@hostname/databasename';

Replace the username, password, and databasename with the values for the database you just created for domain2. hostname should not change because you are presumably using the same MySQL server.

Then point your browser at:

http://domain2.com/install.php

From here on everything should look very familiar.

The result is each website installed under the sites directory in Drupal gets it's own completely separate database and file area. The only thing shared is stuff put in sites/all (some modules and themes can be shared, for instance) and the Drupal code. Separate databases mean that each site must be upgraded separately on Drupal upgrades.

There is reportedly a way of putting all the sites in the same database, but this only simplifies upgrades, while perhaps complicating other aspects of management. I have seen mention of sharing data between sites in this latter case, but it is not yet clear to me how this might be done.
