Nagios 4.3.2 not starting at boot up

I have Nagios 4.3.2 running on a Raspberry PI 3 B on OS raspbian
I've ran the following commands to try to fix nagios starting on boot up but nothing fixes it.
Code: Select all
sudo ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios
If I run
it returns this:
Code: Select all
root@raspberrypi:~# sudo update-rc.d nagios defaults
insserv: warning: current start runlevel(s) (S) of script `nagios' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (empty) of script `nagios' overrides LSB defaults (0 1 6).
insserv: can not symlink(../init.d/nagios, ../rcS.d/S12nagios): File exists
any ideas on what i'm doing wrong?

Can you attach the two following files: /etc/init.d/nagios /etc/rcS.d/S99nagios
Also, what is the output of the following:
Code: Select all
ls -la /etc/init.d/nagios
ls -la /etc/rcS.d/S99nagios
Lastly, do you have systemd available on your system?

Uploaded "/etc/init.d/nagios" to
dropbox (wouldn't let me attach it here) but I didn't find a file at the other path "/etc/rcS.d/S99nagios"
Output
Code: Select all
root@raspberrypi:~# ls -la /etc/init.d/nagios
-rwxr-xr-x 1 root root 8456 Jun 21 14:10 /etc/init.d/nagios
Code: Select all
root@raspberrypi:~# ls -la /etc/rcS.d/S99nagios
ls: cannot access /etc/rcS.d/S99nagios: No such file or directory

What's the output of cat /etc/*lease? I know you gave OS information, but I'm not familiar with raspbian. I know it's based on Debian. I'm hoping the release info will tell me what version of Debian so I can figure out how the init should work.

Code: Select all
[Unit]

After=network.target

Group=nagios
Type=forking
ExecStart=/etc/init.d/nagios start
ExecStop=/etc/init.d/nagios stop

Done..
Code: Select all
root@raspberrypi:/usr/local/nagios/etc/objects# sudo systemctl enable /etc/systemd/system/nagios.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nagios.service to /etc/systemd/system/nagios.service.
Rebooted server and looks like Nagios started up without issue.

It sounds like this issue has been resolved. Is it okay if we lock this thread? Thanks for choosing the Nagios forums!
