Install Nagios on Ubuntu 18.04 Bionic Beaver Linux -

Nagios is one of the best enterprise grade server monitoring solutions available. Unlike cPanel, it's available across a wide range of Linux distributions, including Debian and Ubuntu. Since Ubuntu 18.04 is an LTS release, upgrading your servers and running Nagios on them could be a great idea. Even though Nagios isn't up to date in the Ubuntu repositories, and setup isn't turn-key, it's still not too hard to get it running.

Why build nagios from source even though nagios is available in the repository?


Bri -> Grayson Peddie

Newer version. I think it’s nagios3 in the repo and it’s nagios4 now

In my case, also I have to install php -> “sudo apt install php libapache2-mod-php”


daddydbag -> Juan Manuel Saiz

that was true for me as well.

This should be added to “Install The Requirements”
