2.3. Changing SELinux to enforcing mode

Procedure

1. Open the /etc/selinux/config file in a text editor and configure the SELINUX=enforcing option:

   # This file controls the state of SELinux on the system.
   # SELINUX= can take one of these three values:
   #       enforcing - SELinux security policy is enforced.
   #       permissive - SELinux prints warnings instead of enforcing.
   #       disabled - No SELinux policy is loaded.
   SELINUX=enforcing
   # SELINUXTYPE= can take one of these two values:
   #       targeted - Targeted processes are protected,
   #       mls - Multi Level Security protection.
   SELINUXTYPE=targeted

2. Save the change, and restart the system:

   # reboot

   On the next boot, SELinux relabels all the files and directories within the system and adds SELinux context for files and directories that were created when SELinux was disabled.

Verification

1. After the system restarts, confirm that the getenforce command returns Enforcing:

   $ getenforce
   Enforcing
