You can set the default and current SELinux mode in the Status view of the SELinux Administration GUI.

Alternatively, to display the current mode, use the getenforce command:

# getenforce
Enforcing

To set the current mode to Enforcing, enter:

# setenforce Enforcing

To set the current mode to Permissive, enter:

# setenforce Permissive

The current value that you set for a mode using setenforce does not persist across reboots. To configure the default SELinux mode, edit the configuration file for SELinux, /etc/selinux/config, and set the value of the SELINUX directive to disabled, enabled, or permissive.
