Disabling the firewall and SELinux

Edit online

Temporarily disable both the firewall and SELinux™. This is required before you can reboot the Linux system and test if the prerequisite steps were successfully implemented.

Disable the firewall on boot:
```
# systemctl disable firewalld.service
```
Disable SELinux by editing file /etc/selinux/config and changing the line:
```
SELINUX=[...]
```
to
```
SELINUX=disabled
```
