Update to Nagios Core installation guide needed.
Posted: Wed Jan 30, 2013 4:50 pm
I just installed Nagios for the first time and followed the guide here....
http://assets.nagios.com/downloads/nagi ... Source.pdf
I installed it on CentOS 6.3 64bit using the basic server installation. Once I went through the entire document without errors (except for updating the download version numbers) I was unable to open up the Nagios web page and got a 403 error.
I figured out it was because incoming port 80 connections were not allowed by default in the IPTABLES.
I ran the following commands and everything started working. Would be nice to add to this to the install guide as I spent an hour troubleshooting apache only to figure this out.
Run the following two commands to open up port 80 on CentOS.
