I might be speaking out of turn, but seems to me (and I'm no expert, certainly,) that questions on installing/configuring Apache, PHP and mySQL should be directed to the appropriate list. This list's focus is MediaWiki, not Apache, nor PHP, nor mySQL.
So this list is good for MediaWiki. Apache? PHP, mySQL? Not so much.
My .002 (sic) cents worth.
