Installing a Linux Agent

This document provides instructions on how to set up and install a Linux-based On-Premises Agent to use with Liongard.


Supported Distributions

Currently, the Linux Agent only officially supports Ubuntu and Red Hat. Although most of the data collection is generic to any Linux distribution, thus far testing has only been completed on Ubuntu and Red Hat.

Installing the Agent:


What user should I run the Agent as?

We recommend using a normal local user with sudo access on the system and not running as root.

  • Log in to the Linux system
  • Copy the following script over to the Linux system. Fill out the top-level parameters and save in a file called, ""
    • INSTANCE = Your Liongard instance. You only need to include the first part of the subdomain, "" is assumed
    • AGENT_NAME = The name you wish to give to the Agent
    • DESCRIPTION = An optional description to give to the Agent
    • ACCESS_KEY = Your Access Key from Liongard
    • ACCESS_SECRET = Your Access Secret from Liongard
    • SERVICE_PROVIDER = The name of your company as it appears in the top left corner of your Liongard instance

      • Note: You can remove --environment $ENVIRONMENT from Line #12 below if you wish to associate the Environment via the Liongard UI later
    • USER = The username of the user on the system you wish to run the Agent as
  • Run chmod 775
  • Run sudo
