We need to run several MediaWiki Wikis, that need totally separate user accounts, on the one server. What would be the better solution:
- Use separate source code and use namespaces in the database.
- Use the same source code along the lines of this, essentially you create a customised localsettings.php file for each site that contains the site specific info and you have a master localsettings.php file that depending on the url send you to the relevant site specific localsettings.php
- Symlink all of the source code except for localsettings.php and any other relevant files from a master folder.
Obviously it would be nicer to be able to use the same code for every instance, as it will make upgrades a lot easier.
For what it's worth it will be running on Ubuntu server, Apache with a sprinkling on nginx & MySQL
