Thread:Project:Support desk/Newbie Install

Trying to install MediaWiki 1.22  After clicking the install, I am never prompted for database info, only language for install. After clicking next, I get the following

Connect to database

[a55d1b52] /mediawiki/mw-config/index.php?page=DBConnect Exception from line 788 of /var/lib/mediawiki/includes/db/Database.php: DatabaseBase::factory no viable database extension found for type 'mysql'
