啟動、關閉與觀察

1. SELinux開機啟動模式
   

   [root@deyu ~]# cat /etc/sysconfig/selinux 
   # 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. 關察目前SELinux狀態
   

   [root@deyu ~]# sestatus 
   SELinux status:                 enabled
   SELinuxfs mount:                /selinux
   Current mode:                   enforcing
   Mode from config file:          enforcing
   Policy version:                 24
   Policy from config file:        targeted
   

3. 改變SELinux模式
   

   [root@deyu ~]# getenforce 
   Enforcing
   [root@deyu ~]# setenforce 0
   [root@deyu ~]# getenforce 
   Permissive
   [root@deyu ~]# setenforce 1
   [root@deyu ~]# getenforce 
   Enforcing
