Under GNU/Linux, most distributions (Debian, RedHat, Suse, CentOS, ...) allow you to easily configure a LAMP server. In this tutorial, we will use the GNU/Linux Ubuntu distribution, version 12.04 Long Term Support as an example. Although other distributions will work just fine, Chamilo's development team uses Debian or Ubuntu as preferred distribution of GNU/Linux for their security as well as their very stable and intelligent packaging system, which avoid fighting against dependencies when the need to install new packages presents itself.
