How to Download and Install Nagios XI Offline?

Start by visiting https://repo.nagios.com/?repo=offline and download the Nagios XI Offline RPM Tarball for distribution and architecture.
Then, we upload the downloaded tarball to the server we will be installing Nagios XI on, place the tarball in /tmp/rpms/.
Now you can execute the following commands to install Nagios XI. We need to replace the tarball filename below with the file downloaded;

# cd /tmp/rpms

# tar xzf nagiosxi-5-4.7.el7.x86_64.tar.gz

# cd nagiosxi

# ./fullinstall

Once the installation is completed, we will be able to navigate to our server via a browser to complete the installation;

http://<YOUR_SERVER>/nagiosxi/

Due to the nature of RPM based installs, there will be a simple message that states the installation is complete.
