I have been following this tutorial:

$ sudo systemctl start nagios
Failed to start nagios.service: Unit nagios.service failed to load: No such file or directory.

What is the cause of problem?

I have:

$ sudo /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

I created this file:

 sudo vi /etc/systemd/system/nagios.service

and added the following:

[Unit]
Description=Nagios
BindTo=network.target


[Install]
WantedBy=multi-user.target

[Service]
User=nagios
Group=nagios
Type=simple
ExecStart=/usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg

Then the following:

   sudo systemctl enable /etc/systemd/system/nagios.service
   sudo systemctl  start nagios
   sudo systemctl  restart nagios

    no, but they are allowed to mark them as as the correct answer. You hadn't done that yet. Which was sort of what I was implying: I tried your answer, and it worked for me. Might as well mark it as the "correct" one :D

  • You can also operate it with sudo service nagios <action> - (and configtest now I'm upgrading to nagios4 seems to work properly too - with v3 I used to have to do sudo /usr/sbin/nagios3 -v /etc/nagios3/nagios.cfg)
