Again, here is a tutorial article exposing the recipe I use to cook a Munin on a Debian Squeeze.

As usual, let’s start by installing the main Munin package:

$ aptitude install munin
FYI, the version that aptitude choose to install was Munin 1.4.5. The default configuration coming along will make it produce graphs and HTML content to /var/cache/munin/www. Now we need to serve these pages via a web server.

As I wanted to play with nginx for a long time, I will use this opportunity to serve Munin’s content. The default version coming with Squeeze is quite old, so we’ll get the latest version from the Dotdeb repository:
