If you're running the Zabbix on CentOS 8 with SELinux enabled on it, then you must do all command on this section.

Install SELinux utilities using the dnf command below.

dnf install policycoreutils checkpolicy setroubleshoot-server

Once the installation is complete, create a new directory '~/zabbix-linux' and go into it.

mkdir -p ~/zabbix-selinux
cd ~/zabbix-selinux/
