#     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.

解决方法：

1、重启Linux按e进入系统启动项修改参数

2、在linux16的行位添加 selinux=0

按ctrl + x之后启动linux系统

3、启动之后修改/etc/selinux/config文件
