Linux Client fullinstall CentOS 7

[rnadon]

Hiya Nagios experts,
Got a weird one here.
I have 3 CentOS 7 boxes that I need to monitor. The first two went perfectly and everything works. On the third one the install said successful. Here is the results of rerunning fullinstall

If you experience any problems, please attach the file install.log that was just created to any support requests.

However the service is not found and it looks like nothing much was done?!?
if you look at my locate (yes I did an updatedb to make sure the new stuff was taken into account) I am missing /etc/nagios and /usr/sbin/nagios, which are on my other two that successfully installed.

Also there is no install.log file to be seen?!?

-bash-4.2# locate install.log

Has anyone seen this before?
Thanks in advance,

I am missing /etc/nagios and /usr/sbin/nagios, which are on my other two that successfully installed.

This is the agent installer, so these would only be present if you installed them a different way, maybe via package manager.

This installer touches a file in this directory for each step when it is completed like "installed.*" that it looks for so it doesn't have to re-run the steps if they have already run and fullinstall is run again.

This installer should install nrpe under /usr/local/nagios/bin/nrpe
also the xinetd loader, with a config at /etc/xinetd.d/nrpe

The configuration file for nrpe is at

Code: Select all

/usr/local/nagios/etc/nrpe.cfg
/usr/local/nagios/etc/nrpe/common.cfg

If you want to re-run the agent from scratch you can run the following

Code: Select all

rm -f installed.*
./fullinstall

[rnadon]

Yes, I installed the first time and then reran fullinstall to illustrate that the installer to illustrate that it thought it installed everything. Good advice for the rm -f installed.* (I figured out that it was from the install directory) for me that was /tmp/linux-nrpe-agent
After a reinstall everything stated working though a run of service nagios status returns no such service. But that is OK I believe there is something weird or missing in the OS itself. The two boxes that worked right away, I installed the OS the other one I did not, so ...

But we are back up and running with a completely empty <All Service Problems> on Nagios

Thanks so Much.
Robert

Yes, this is just the agent, so nagios is not installed. Glad it is all good now!
