Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-itk On Ubuntu 9.10 This article explains how you can install and configure apache2-mpm-itk on an Ubuntu 9.10 server. apache2-mpm-itk is an MPM (Multi-Processing Module) for the Apache 2 web server. mpm-itk allows you to run each of your vhost under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. mpm-itk works with mod_php because mpm-itk is based on the traditional prefork MPM, which means it's non-threaded. This means you don't need to use suExec or suPHP anymore to run a website's PHP scripts as a separate user.
