Nagios is a good open source montoring tool. When trying to install nagios to our ubuntu server, I find there are lot of scattered documentation on the web, but not a single complete one that walk you step by step on how to install it to Ubuntu 9.04 Jaunty server. After encounter many dependency problems, espeically with the nagios plugin, I decided to do a total clean install in a valila server and record each steps. Hopefully, it will be useful to others who might want to install Nagios 3 to Ubuntu Jaunty.
Step I : Get a basic Ubuntu Jaunty OS server ready.
