Option to disable SELinux for AL2027

When you disable SELinux, SELinux policy isn't loaded or enforced and Access Vector Cache (AVC) messages aren't logged. You lose all benefits of running SELinux.

Instead of disabling SELinux, we recommend using permissive mode. It costs only a little more to run in permissive mode than it does to disable SELinux completely. Transitioning from permissive mode to enforcing mode requires much less configuration than transitioning back to enforcing mode after disabling SELinux. You can label files, and the system can track and log actions that the active policy might have denied.

For information about how to change to permissive mode, see Change to permissive mode.

Disable SELinux

When you disable SELinux, SELinux policy isn't loaded or enforced, and AVC messages aren't logged. You lose all benefits of running SELinux.

To disable SELinux, use the following steps.

  1. Ensure that the grubby package is installed.

    rpm -q grubby
grubby-version

  2. Configure your bootloader to add selinux=0 to the kernel command line.

    sudo grubby --update-kernel ALL --args selinux=0

  3. Restart your system.

    sudo reboot

  4. Run the getenforce command to confirm that SELinux is Disabled.

    $ getenforce
Disabled
