Can't start NRPE service CentOS

[jbruyet]

Hey all, I have Nagios up and running and monitoring my Windows machines. Now I'm trying to get it to monitor my Linux servers and I've hit a bit of a snag. I downloaded nrpe-2.12.tar.gz and installed it, downloaded nagios-plugins-1.4.14.tar.gz and installed it, but when I try to start the service I get "nrpe: unrecognized service." When I run /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d I get a line feed and nothing else (I've grepped services and there's no nrpe). I've tried it with -i too but no joy. The only thing I can figure is that I messed up the install, but there weren't any errors. Anyone have any ideas?

Thanks,

Joe B

What do you see, when you run:

Code: Select all

# ls /usr/local/nagios/libexec | grep nrpe

Hi lmiltchev, here's what I see when I run your command:

[root@CentOS54 jobee]# ls /usr/local/nagios/libexec | grep nrpe
check_nrpe
[root@CentOS54 jobee]#

FWIW here's the file info:

-rwxrwxr-x 1 nagios nagios 62313 Feb 16 09:02 check_nrpe

Thanks,

Code: Select all

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

This by itself launches a daemon, so it was actually running while you were seeing the empty line feed. If you ran:

Code: Select all

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d &

You'll fork the process to the background. Do you have an init script in /etc/init.d/nrpe? If so you could just run:

Code: Select all

/etc/init.d/nrpe start

Hi mguthrie,

Code: Select all

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

This by itself launches a daemon, so it was actually running while you were seeing the empty line feed.

I'm not new to Linux but I'm not up to guru status yet either. Even so, shouldn't I have been able to ps aux | grep nrpe and find nrpe running?

If you ran:

Code: Select all

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d &

You'll fork the process to the background.

Ok, I ran that command, grepped ps and found nrpe running.

Do you have an init script in /etc/init.d/nrpe? If so you could just run:

Code: Select all

/etc/init.d/nrpe start  

I have an init script now. I actually put the "&" command in the script so grepping can tell me if it's working.

Thanks for the help,

Joe B
