Nagios Support Forum

Hi,

We are trying to install the linux nrpe agent on a server to be monitored by nagios using the check_nrpe plugin.

Following the guide https://assets.nagios.com/downloads/nag ... _Agent.pdf we did all the setup.

./full install gives the below message, but i dont see any folder as /usr/local/nagios...

Proceeding with installation...
Running './0-repos'...
Repos already configured - exiting.
RESULT=0
Running './1-prereqs'...
Prereqs already installed - skipping...

Will it be stored inside .tmp itself.?

And when i tried to add the server in Nagios XI, I am getting error as "(No output on stdout) stderr: connect to address xx.xxx.xx.xx port 5666: No route to host"

In the above documentation there are no clear steps on configuration files to allow port 5666 , firewall, xinetd etc..

Could you provide with documentation if any other or advise on the above.

Thanks.

Yeah, you should see /usr/local/nagios directory, it must not have installed properly.

Remove the install directory that you ran fullinstall from, re-extract it, run the ./fullinstall again and send us the ENTIRE output.

Thank you

I had deleted the folder.

Re-extracted it and tried to run ./fullinstall and below is the output.

It shows Installation complete but still I am not able to see the /user/local/nagios directory..Strange.!!!

[root@test linux-nrpe-agent]# ./fullinstall
Your system $PATH does not include /sbin and /usr/sbin. This is usually the result of installing GNOME rather than creating a clean system.
Adding /sbin and /usr/sbin to $PATH.

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

Can you run the following commands on the client (remote machine), and show the output? Are you using a proxy? Is the client machine connected to the Internet? You are not running the script in an offline environment, are you?

Remove all of the files named "installed.xxx", e.g. "installed.repos", and rerun the script, enabling debugging:
If the agent is still not installed, post the entire output. Also, post the install.log file.
