关闭selinux

1、通过命令“getenforce”获取selinux状态，

getenforce
//enforceing代表开启
//permissive代表警告
//disabled代表关闭

2、在终端输入命令即可关闭selinux，此种做法只是暂时关闭，重启之后没有效果

setenforce 0  //关闭
setenforce 1  //开启

3、通过配置文件“/etc/sysconfig/selinux”来修改selinux状态，此种做法需要重启机器

vi /etc/sysconfig/selinux
# 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

4、通过修改“/boot/grub/menu.lst”来关闭selinux，这样每次开机都不会启动selinux

vi /boot/grub/menu.lst 
---------------------------------
default=0

timeout=5
