Purpose

This document describes how to manually install Nagios Log Server from source on a Debian 12 system.

Target Audience

This document is written for administrators who are looking to perform a new installation of Nagios Log Server on a Debian 12 machine, rather than using a pre-configured virtual machine image.

Platform Support

Nagios Enterprises provides support for installing Nagios Log Server on Debian 12 and other Linux Distributions (Only 64-bit supported):

See Nagios Software/OS compatibility matrix

If you discover bugs or have fixes for installing Nagios Log Server on other platforms, please let us know. We will do our best to incorporate your improvements to expand support for additional platforms in future Log Server releases, which will make future installation processes smoother for you and your clients.

Installation Prerequisites

Important: Nagios Enterprises highly recommends and will only support installing Nagios Log Server on a newly installed, “clean” system (a bare minimal install with nothing else installed or configured). 

Attempting to install Nagios Log Server on a pre-existing system with other applications already installed can cause the Nagios Log Server installation process to fail, critical system components and settings (e.g.

database servers) to be modified in a way that negatively affects other applications, and previously installed applications to be automatically upgraded or removed. While installing Log Server on a system with other applications is possible, it is not recommended due to the possible interactions and complexity of multiple components that are required for Nagios Log Server to function. If you choose to ignore these warnings, you do so at your own risk.

Other Nagios products (XI, Network Analyzer and Fusion) should not co-exist on the same server.

Internet access is required for installation and upgrades!

Terminal Access

These instructions require you to establish a terminal session to the server you plan to install Nagios Log Server on. You will need to login to your server as the root user to perform the installation.

Install Nagios Log Server

To check if curl is installed, you can run:

bash

curl --version

If it’s not installed, you can easily install it with:

bash

sudo apt update
sudo apt install curl

There are two methods for installing Nagios Log Server, they both perform a full installation, quick and manual.

Quick

That command will download and install Nagios Log Server. Proceed to the Finalize Installation section.
