Nagios Support Forum

Hello everyone... I need help, i apologies before hand if what am asking common knowledge to many of you. But I am stack. I keep getting the error below, i have failed to get/find the fix, again AM totally new at this.
I managed to install Nagios, but it is failing at the following:

[root@va31svaxngs nagiosxi]# ./fullinstall
========================
Nagios XI Full Installer
========================

This script will do a complete install of Nagios XI by executing all necessary sub-scripts.

IMPORTANT: This script should only be used on a 'clean' install of CentOS, RHEL, Ubuntu LTS, Debian, or Oracle. Do NOT use this on a system that has been tasked
with other purposes or has an existing install of Nagios Core. To create such a clean install you should have selected only the base package in the OS installer.
Do you want to continue? [Y/n] Y
Proceeding with installation...
Checking MySQL credentials...
MySQL not yet installed - that's okay.
Running './0-repos'...
