一、查看SELinux狀態:
1、我們可以通過查看配置文件的命令 cat /etc/selinux/config 來查看狀態
[root@lill ~]# 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=enforcing
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
發現SELinux共有3個狀態enforcing (執行中)、permissive (不執行但產生警告)、disabled(關閉)。
2,也可以用這個命令檢查:getenforce
[root@localhost /]# getenforce
Enforcing
3、也可以用下述命令;如果SELinux status參數為enabled即為開啟狀態
[root@localhost /]# /usr/sbin/sestatus -v
SELinux status: enabled
二、關閉SELinux:
1、臨時關閉(重啟機器后失效):
#setenforce 0設置為permissive模式;setenforce 1 設置為enforcing模式;
setenforce 0
2、永久關閉(需要重啟機器):
sed -i s#SELINUX=enforcing#SELINUX=disabled# /etc/selinux/config
重啟機器即可
