# 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

设置方法：

1      #SELINUX=enforcing     #注释掉

2      #SELINUXTYPE=targeted  #注释掉

3      SELINUX=disabled  #增加

4     :wq  #保存，关闭。

5     shutdown -r now   #重启

完整修改后如下：
