- 查看SELinux状态
1.1 getenforce
getenforce 命令是单词get（获取）和enforce(执行)连写，可查看selinux状态，与setenforce命令相反。
setenforce 命令则是单词set（设置）和enforce(执行)连写，用于设置selinux防火墙状态，如： setenforce 0用于关闭selinux防火墙，但重启后失效
[root@localhost ~]# getenforce
Enforcing
1.2 /usr/sbin/sestatus
Current mode表示当前selinux防火墙的安全策略
[root@localhost ~]# /usr/sbin/sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28
SELinux status：selinux防火墙的状态，enabled表示启用selinux防火墙
Current mode： selinux防火墙当前的安全策略，enforcing 表示强
- 关闭SELinux
2.1 临时关闭
setenforce 0 ：用于关闭selinux防火墙，但重启后失效。
[root@localhost ~]# setenforce 0
[root@localhost ~]# /usr/sbin/sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28
2.1 永久关闭
修改selinux的配置文件，重启后生效。
打开 selinux 配置文件
[root@localhost ~]# vim /etc/selinux/config
修改 selinux 配置文件
将SELINUX=enforcing改为SELINUX=disabled，保存后退出
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 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
此时获取当前selinux防火墙的安全策略仍为Enforcing，配置文件并未生效。
[root@localhost ~]# getenforce
Enforcing
重启
[root@localhost ~]# reboot
验证
[root@localhost ~]# /usr/sbin/sestatus
SELinux status: disabled
[root@localhost ~]# getenforce
Disabled
