# 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=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

Enforcing
[[email protected] ~11:00:55]#setenforce
usage:  setenforce [ Enforcing | Permissive | 1 | 0 ]

數字0表示：Permissive，即給出警告提示，但不會阻止操作，相當於disabled。

數字1表示Enforcing，即表示Selinux為開啟狀態。
