Thread:Project:Support desk/start wiki at boot up on os x lion/reply

MediaWiki is not a desktop application. You can't "start" it.

I assume you mean you want to start Apache and MySQL at boot up ?

This is very possible, but depends on which Apache/MySQL you use. If you use the default Apache that comes with OS X, then all you have to do is enable it from the System Preferences > Sharing > Web Sharing and then it will be started right away and also starts when the system boots up (I do this myself as well).
