系统：centos6.x
vim /etc/selinux/config
修改后的值: SELINUX=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 - SELinux is fully disabled. SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
查看状态：sestatus
状态不为disabled，则重启
[root@iZwz9eczt2tstmhvm8mv25Z docker]# sestatus SELinux status: disabled [root@iZwz9eczt2tstmhvm8mv25Z docker]#
