Disabling SELinux

You can fully disable SELinux by setting the selinux kernel parameter to zero.

Important:

Oracle doesn't recommend disabling SELinux in production systems. Use permissive mode instead.

Set the required kernel parameter.
Use the grubby utility to set the selinux parameter to zero:
```
sudo grubby --update-kernel ALL --args selinux=0
```
Restart the system.
Check that SELinux is disabled.
Run the getenforcing command and verify that the output is Disabled:
```
getenforcing
Disabled
```
(Optional) Reenable SELinux
To reenable SELinux, enter the following command and restart the system:
```
sudo grubby --update-kernel ALL --remove-args selinux
```
