#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

解決方法:

1、重啟Linux按e進入系統啟動項修改參數

 

 2、在linux16的行位添加 selinux=0

按ctrl + x之后啟動linux系統

 

 

3、啟動之后修改/etc/selinux/config文件
