Your system $PATH does not include /sbin and /usr/sbin. This is usually the
result of installing GNOME rather than creating a clean system.
Adding /sbin and /usr/sbin to $PATH.

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.

Hi dchurch

Thank you so much,

now I can see Nagios webinterface but when I type https://myaddress/nagiosxi

it's shows Not Found
The requested URL was not found on this server.

Please check, that attach file.

Your install.log does not contain the successful installation. Did you grab the wrong one?

Please run the ./fullinstall command again and send the entire output.

We would need to see that one to see what failed during the install process. It must not have installed properly.

Do you have this file? If so, please attach it:
What is the output of this command?

Hi ssax

The system looks customized, you should install fresh on an unmodified minimal install of CentOS 8 (outside of IP changes) and you will likely not have any issues.

Your repos have issues, it can't find the packages it needs. What is the full output of these commands?
Try doing this first then run the ./fullinstall command again:
If you skipped through anything to get it to install then you should delete the current install directory you ran ./fullinstall from, re-extract the package and run ./fullinstall again.

What does /var/log/mariadb/mariadb.log show?
