XI 5.x Manual Installation Instructions
Note: Nagios XI can only be installed to CentOS Stream 9, RHEL and Oracle Linux 8 and 9, Debian 11 & 12, and LTS versions of Ubuntu 20.04, 22.04 and 24.04.
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!
