Came into work this morning and the following services are down

This is a problem, SELinux needs to be disabled for Nagios XI to function properly

Run the following

Code: Select all

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

You likely will need to reboot the XI server after doing this
