关闭centos中的SELinux

SELinux可以简单的理解为增加了安全性的linux系统，更多的理解，可以自行寻找答案，这里不再复述，下面是关闭SELinux的方法。

首先，使用getendorce或者sestatus命令查看当前selinux的状态，如果是非关闭的状态，就继续关闭它。

然后找到 /etc/selinux/config文件，如下：

# 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 - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

将其修改为：

# 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=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

另外，还需查看启动菜单文件： /boot/grub/menu.lst中是否有selinux=0这个选项，如果存在，则必须要将其删除才可。

最后重新启动系统，就OK了。
