Nagios is Failing to Start

Post by tbyrd82 »

Hi everyone,

I am trying to get Nagios Core up and running on Ubuntu but am having a hard time actually getting it to function.

I'm running Ubuntu Ver. 18
and Installed Nagios Core: 4.4.5

I did a clean install using Nagios' website and once it is installed it wont start. If i run "sudo systemctl start nagios.service" I get:

Job for nagios.service failed because the control process exited with error code.
See "systemctl status nagios.service" and "journalctl -xe" for details.

Here is "systemctl status nagios.service":



nagios.service - Nagios Core Monitoring Daemon

First, let's run a verification of the Nagios configurations to see if there are any errors. Run the following as root and post the output here so we can view it.

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
If you see any errors, that would stop the process from starting so fix the errors and try starting the nagios process again.
