1. 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
2. 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
