I recommend checking out the "Howto Forge"
http://www.howtoforge.com/installing-apache2-with-php5-and-mysql-support-on-mandriva-2010.1-spring-lampThere are several other guides for Mandriva and Apache with various configurations on the site.
You will find all sorts of useful configuration guides for a whole range of distros not just 'buntu/Debian.
Any Howto written for Mandriva should apply equally well for Mageia, and to a lesser extent you can use guides written for PCLinuxOS.
