The latest versions of Nagios may not always be available on the Ubuntu repository. Following this tutorial, you can install the latest version or choose a specific version that you want to install of Nagios. But, of course, you can install it using the official repository of Ubuntu, if you prefer.

Steps 2, 4 and first half of step 5 can be entirely replaced with an «apt install nagios4 nagios-plugins-contrib nagios-nrpe-plugin monitoring-plugins» command.
Then All «/usr/local/nagios/etc/» paths when editing can be replaced with «/etc/nagios4/».

The only thing needed from step 5 would be the configuring of the contact name and email address, and adding clients using the nrpe editing lines.

There is No need to download and manually configure all of the above steps listed, when they are mostly automated by installing the nagios packages from the official Ubuntu repositores.

Change the word “server-ip-address” to your actual server IP address.

In what order or what line do you change your IP here? If you can provide example that would be great.

server_address=client-ip-address
allowed_hosts=127.0.0.1,::1,server-ip-address

Also, do you need to change your IP here?

nano /etc/nagios/nrpe_local.cfg

And here?

nano /usr/local/nagios/etc/servers/nagiosclient.cfg

Thanks,

Peter
