禁用SELinux

一、临时禁用SELinux：
root@BCentOS# setenforce 0
    
这样重启服务器以后，仍是会启动SELinux，
二、永久禁用：
打开服务器上的SELinux配置文件，默认为：/etc/selinux/config，内容以下：

# 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=enforcing
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted

将上面的
SELINUX=enforcing 改成：SELINUX=disable  禁用SeLinux
