Simple Nagios Install Script

Preamble

This is just a stupid simple installation script originally Nagios 4.3.4, on Ubuntu 16.04, and is compatible with 18.04 LTS

The script is written in bash, and handles dependency installation, user and group creation, Nagios core installation, as well as the basic plugins.

this script is basic, not pretty, not commented, and lacks upkeep, user beware.
