The following are some of the most commonly used SELinux utilities:
/usr/bin/setenforce — Modifies in real-time the mode SELinux is running. By executing setenforce 1, SELinux is put in enforcing mode. By executing setenforce 0, SELinux is put in permissive mode. To actually disable SELinux, you need to either set the parameter in /etc/sysconfig/selinux or pass the parameter selinux=0 to the kernel, either in /etc/grub.conf or at boot time.
/usr/bin/sestatus -v — Gets the detailed status of a system running SELinux. The following example shows an excerpt of sestatus output:
SELinux status: enabled SELinuxfs mount: /selinux Current mode: enforcing Policy version: 18
/usr/bin/newrole — Runs a new shell in a new context, or role. Policy must allow the transition to the new role.
/sbin/restorecon — Sets the security context of one or more files by marking the extended attributes with the appropriate file or security context.
/sbin/fixfiles — Checks or corrects the security context database on the file system.
Refer to the man page associated with these utilities for more information.
