Selinux的三种模式宽容模式（permissive）强制模式（enforcing）关闭（disabled）

1、vim /etc/selinux/config Selinux的配置文件
# 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, 目标流程受保护
# minimum - Modification of targeted policy. Only selected processes are protected. 选定的受保护
# mls - Multi Level Security protection. 多级安全保护
SELINUXTYPE=targeted

enforcing：强制模式，代表Selinux运行中，
permissive：
disabled：

临时更改Seinux的模式：
setcnforce 0 临时关闭
setenforce 1 临时打开
