1、查看
[root@dev-server ~]# getenforce
Disabled
[root@dev-server ~]# /usr/sbin/sestatus -v
SELinux status:                 disabled
2、临时关闭
##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
setenforce 0
3、永久关闭
vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled 
设置后需要重启才能生效

 

centos 7.0 查看selinux状态|关闭|开启
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。

查看selinux状态
 
[root@localhost ~]# 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
临时关闭
 
[root@localhost ~]# 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。

 
[root@localhost ~]# 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  
SELINUX=disabled  
# 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
 
[root@rdo ~]# sestatus  
SELinux status:                 disabled
