关闭SELinux功能

讲解下关闭SELinux的功能

1. 首先查看下selinux的状态,命令:getenforce
[root@rsync ~]# getenforce 
Disabled

2. 查看selinux的配置文件,命令:cat /etc/selinux/config
# 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=disabled
# SELINUXTYPE= can take one of these two values:
#    targeted - Targeted processes are protected,
#    mls - Multi Level Security protection.
SELINUXTYPE=targeted

3. 把SELINUX=enforced改为SELINUX=disabled
方法1:vi编辑器修改
方法2:sed命令:sed –I ‘s#SELINUX=enforced#SELINUX=disabled#g’
4. 修改后的文件需要重启才能生效,但是企业服务器24小时是不能关机重启的。所以需要另外一种方法,可以使用setenforce命令设置临时生效关闭,不用重启生效。
命令:setenforce 0
