Nagios stop working

[dwhitfield]

Others have had success eliminating this error re-compiling the following items.

Code: Select all

make install-init
systemctl enable nagios.service
systemctl enable httpd.service

make install-commandmode
make install-config
make install-webconf

It looks like you still have the vestiges of the old install, so please make sure you are re-compiling using the 4.2.1.

Don't quote me but , it seems u did compile Nagios by your self
and then installed NRPE using YUM
The problem here is that Yum installs bit older versions of everything and NRPE from repo comes configured for totally different directories like : in case of compilation /usr/local/nagios/etc/ vs /etc/nagios/ in case of YUM installation.
I believe best choice would be to roll back last install, if NRPE was installed using yum just
yum remove nrpe
get older version of nrpe (ask lads here which one is compatible with your version of nagios the best, and recompile it)

I compiled NRPE after I had Nagios up and running

What directory do I have to been in to issue these commands
ake install-init
systemctl enable nagios.service
systemctl enable httpd.service

make install-commandmode
make install-config
make install-webconf

Well, the instructions at https://support.nagios.com/kb/article.php?id=96 say /tmp/nagioscore-nagios-4.2.1/, but the real answer is wherever you unpacked the 4.2.1 tarball.

[rbizzell39]

okay thanks! I will try that

[dwhitfield]

Awesome. Also, FYI that unless you set something else up, /tmp is ok to use in CentOS. Debian and at least some derivs automatically flush that, but CentOS does not.

Thanks for all your help

[dwhitfield]

No problem, that's what we're here for!
