Failed to start Nagios Core Service on CentOS 7

[karlossimo]

I have deployed Nagios Core on a CentOS 7 server. I have followed all the commands as listed on the installation guide

https://assets.nagios.com/downloads/nag ... entos7.pdf

Everything has gone fine but when I try to start the Nagios service using the command

Code: Select all

sudo service nagios start

I get the following error:

Starting nagios (via systemctl): Job for nagios.service failed because the control process exited with error code. See "systemctl status nagios.service" and "journalctl -xe" for details.
[FAILED]

I also created a file /etc/systemd/system/nagios.service as per some recommendations from ohter discussions as I was previously getting a error code 1 before.

nagios.service INFO

Code: Select all
