centos 7关闭selinux

如果要临时关闭，可以执行
setenforce 0 

查看状态
# 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:          disabled
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Max kernel policy version:      28

如果要永久关闭，可以修改配置文件/etc/selinux/config，将SELINU置为disabled。


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  

修改该配置文件也可以执行下面的命令来完成
 sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
