linux-nrpe-agent uninstall / remove

[Nags007]

Hi Team,
I am using RHEL 6.8. I have installed the linux-nrpe-agent without NagiosXI server IP.

I want to uninstall the linux-nrpe-agent , is there any uninstall scripts available

Reason: want to install linux-nrpe-agent freshly install it, so that when it asks for NagiosXI server IP i can enter. or where to enter NagiosXI server IP in the Agent files ? how many files i need to enter NagiosXI Server IP in the linux-nrpe-agent files ?

Please guide.

Thank you,
Nag.

In /usr/local/nagios/etc/nrpe.cfg you should change the allowed_hosts= line. You'll need to open firewall ports and such too.

NRPE 3 comes with an uninstall script. You can get NRPE 3 from github. However, the one branded as the linux agent is NRPE 2.15 and does not have an uninstall script. We can help you uninstall it if you still prefer to go that route.

I have changed the NagiosXI Server IP in below line. /usr/local/nagios/etc/nrpe.cfg
#allowed_hosts=127.0.0.1

and entered the new serverIP there.

Thank you,
Nag

For clarity, you did not leave it commented correct? I just notice the #. Also, is it working for you now?

Please note:

Right now, I have started with Nagios Agent installation as i know the IP of NagiosXI server.
I have not installed NagiosXI server yet.

==========================================================
Actually i have installed the linux-nrpe-agent on other system( new client). there during the installation i gave the NagiosXI server IP, which i know.

That NagiosXI Server IP entered, is not recorded or inserted in the Allowed HOST tag in /usr/local/nagios/etc/nrpe.cfg ( which you mentioned).

==============================================================

I have already installed almost 20+ agents.


I would like to uninstall or remove the linux-nrpe-agent and freshly install the nrpe agent as i know the New NagiosXI server IP now.

Earlier entered NagiosXI server was decomissioned so i need to change the NagiosServer IP, in many files of NagiosAgent i guess. ( i am not sure ).

=========================================================================

I have downloaded to below /tmp folder. I can see the below files there.

/tmp/linux-nrpe-agent/

Code: Select all

delgroup nagios
deluser nagios
rm -f /etc/xinet.d/nrpe
service xinetd restart
rm -rf /usr/local/nagios

...but changing the one file should do it, if you have the ports open.

Thank you very much. I am able to uninstall and reinstall the agent again.

Thanks a lot

[dwhitfield]

Did reinstalling the agent resolve your issue?

[Nags007]

I am doing Nagios XI server installation now as i got the sudo / root access now. Will update you soon.

Thanks,

[dwhitfield]

Ok, great!

One thing I will note since you mentioned sudo access. Modified sudoers files can mess things up, so just be careful.
