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 # 将这个更换为 disabled

SELINUXTYPE= can take one of these two values:

targeted - Targeted processes are protected,

mls - Multi Level Security protection.

SELINUXTYPE=targeted

 

2.关闭内存中selinux规则
setenforce 0
