Which version of Nagios are you trying to install? Are you following a guide for the install (provide the link) or how did you install it?

By what means are you starting the process?
Are you calling the binary or are you using an init script? It looks like SUSE recently quit working with our init scripts altogether and perhaps you're in the same boat.

After each time my server restarted i need to manually restart the process using following command:
As per my guide line there is a script at
/etc/init/nagios.conf
Code: Select all
description "nagios 4.x core"
start on filesystems
stop on runlevel [1246]
respawn
setuid nagios
setgid nagcmd
console log
script
exec /usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg
end script
I beleive this script is no longer working. What should modification can do the resoluation? Or please do suggest some possible way to fix it.

Here's what I had to do to get it running:
Create /etc/systemd/system/nagios.service with the contents below:
Code: Select all
[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:
Code: Select all
sudo systemctl enable /etc/systemd/system/nagios.service

Thanks a lot. It works. Would you mind to describe me a little bit about this steps? It would help me to make similiar script for my other services as well.
Again thanks a lot!
Admin can close this thread!

I'll expand on ssax's answer a bit. Here is some a more thorough systemd script:
Code: Select all
[Unit]
Description=Nagios Core Monitoring Daemon
After=network.target
[Service]
User=nagios
Group=nagios
Type=forking
ExecStart=/usr/lib/systemd/scripts/nagios start
ExecStop=/usr/lib/systemd/scripts/nagios stop
ExecReload=/usr/lib/systemd/scripts/nagios reload
[Install]
WantedBy=multi-user.target
It actually leverages the logic we have built into the original init script so you can use it to reload your daemon after you've changed configs ... safely. You will need to relocate /etc/init.d/nagios to the path shown (/usr/lib/systemd/scripts/).
