Nagios XI – Installing The Linux Agent - Details

[bkoutsob]

The installation procedure at a point states the following:

This will automatically take care of a number of things for you, including
•Modifying the yum configuration
•Installing prerequisite packages
•Creating required uses and groups
•Defining services
•Compiling and installing the agent and plugins
•Configuring sudo and the firewall
•Configuring the agent

Are there details on the exact steps and changes that are made to the system? Those descriptions are quite vague.

Thank you in advance

If you need the exact steps, it doesn't get any more exact than reading the script itself, but to expand somewhat on each step:

•Modifying the yum configuration
Adds the proper repositories to the yum configs so all the dependencies can be installed

•Installing prerequisite packages
Installs said dependencies

•Creating required uses and groups
This is done so not everything is run as root, but rather an appropriately-privileged user

•Defining services
I believe this is referring to the init scripts

•Compiling and installing the agent and plugins
Pretty obvious

•Configuring sudo and the firewall
Allows certain commands to be run as root via sudo, and opens the firewall to allow incoming checks

•Configuring the agent
Sets some sane defaults and standard commands like check_load
