I've been running a MediaWiki farm at thingelstad.com for a couple of years now hosting about a dozen wikis ranging from small to very large. Running a MediaWiki farm is a bit complicated and you can approach it a number of different ways. I recently pushed the settings that I use to run my farm into GitHub so others can see how I do it. The next step will be to also move the scripts that I use up, but those will be kept in another repository. Hopefully this proves useful to others. It’s useful for me to finally have these very complicated settings (really code!) under version control.
