centos 7.0 查看selinux状态|关闭|开启

Posted 2020-11-04 爱吃醋的工程师

Linux在安装好之后通常SELinux都是出于默认开启的状态，开启的情况下会导致一些服务的安装不成功。

在不需要的情况下完全可以关闭掉,下面是在centos 7.0里面如何查看，关闭selinux。

[[email protected] ~]# setenforce 0 

永久关闭,可以修改配置文件/etc/selinux/config,将其中SELINUX设置为disabled。

# 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.

# SELINUXTYPE= can take one of three two values:
