I am just starting to upgrade / install Ubuntu 14.04 on my servers, so it’s time to create a guide to install Nagios 4 on Ubuntu 14.04. Apparently Nagios Core install scripts wern’t well tested for Debian systems. But in any case, it can be installed with a couple modifications.
This guide is going to be very similar to my other Nagios install guides.
If there is an application I publish in an LDAP or Active Directory environment, I will implement LDAP authentication if that option is available – no sense is making users apply another user name / password sticky note to their monitor, right?
Converting a couple directories to tmpfs will significantly reduce disk I/O by Nagios for status updates.
I do not have Nagios 4.x on any production boxes yet, but I want to keep track on how this is working on Ubuntu 12.04. Apparently Nagios Core wasn’t well tested for Debian systems if at all. But in any case, it can be installed with a couple modifications.
This guide is going to be very similar to my guide on Nagios 3.x.
Update: Are you already on Ubuntu 14.04? Head on over here
for the latest guide.
When I deploy a new Nagios box, I always start with this. I do not use deb packages here because they are too many versions behind. Plus, I like to have full control over how this is configured.
