Install Munin 2.0.x on Ubuntu 12.04

Ubuntu 12.04 is still one of the most popular linux distros with LTS term, yet it is packaged with a very outdated munin 1.4.6 binary distribution.

Munin is a networked resource monitoring tool that can help analyze resource trends and “what just happened to kill our performance?” problems. It is designed to be very plug and play. A default installation provides a lot of graphs with almost no work.

Since it took me so much time to get munin 2.0.x working on Ubuntu 12.04, I write and share this tutorial as a reference in the hope of saving some of your quality time in case you need to do the same thing.

1. Add Munin Backport PPA

2. Build munin dependencies and installation

3. Configure munin

Edit /etc/munin/munin.conf and update graph_strategy and html_strategy setting to cgi.

4. Enable munin plugins

5. Update apache configuration

Edit /etc/munin/apache.conf

You are done. Goto the browser and visit http://your-domain/munin.
