Installation Options

There are two options available for installing Nagios XI:

  • Use the Nagios XI VMware virtual machine. This is the fastest way to get up and running with Nagios XI. The VMware machine can also be used in enterprise environments where VMware ESX, vSphere or other VMware server products are deployed.
  • Install Nagios XI manually. Use this option if you wish to install Nagios XI on a physical server (e.g. for performance reasons) or a virtual server running a supported Linux distro.

Choose the option best suited for your needs. If in doubt, we recommend using the Nagios XI VMware virtual machine to get up and running quickly.

Running Under VMware ESX

The Nagios XI VMware virtual machine is designed to run under VMware Player or Workstation. If you'd like to run the Nagios XI VMware virtual machine under VMware ESX, you'll need to convert the machine image using VMware Convertor. This video tutorial below takes you through the necessary steps to get up and running quickly.

Manual Installation

Experienced Nagios administrators who want to install Nagios XI on their own physical or virtual Linux servers can use this guide to get started.

XI Manual Installation Instructions

Note: Nagios XI can only be installed to RHEL and CentOS Linux distributions.

Important: Nagios Enterprises highly recommends and will only support installing Nagios XI on a newly installed, "clean" system. Attempting to install Nagios XI on a pre-existing system with other applications already installed can cause the Nagios XI 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 XI 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 XI to function. If you choose to ignore these warnings, you do so at your own risk.

Internet access is required for installation and upgrades!

Installing Nagios XI In An Offline Environment

The purpose of this documentation is to provide a guide for installing Nagios XI in an offline environment. The procedure in this document is currently in BETA phase, we do not guarantee these for production at this point, as we are still doing some final internal testing.

This guide is directed towards Nagios XI administrators interested in installing Nagios XI onto systems potentially isolated from the internet or with other internal access only restrictions. This procedure is NOT intended to upgrade a system that was originally installed online or started as a pre-created VM and then moved offline.
