关闭selinux
1、通过命令“getenforce”获取selinux状态，
|
[root@localhost ~]# getenforce
Enforcing //enforceing代表开启，
[root@localhost ~]# getenforce
Permissive // permissive代表警告
[root@localhost ~]# getenforce
Disabled //disabled代表关闭
[root@localhost ~]#
|
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
|
[root@localhost ~]# setenforce 0 //关闭
[root@localhost ~]# getenforce
Permissive
[root@localhost ~]# setenforce 1 //开启
[root@localhost ~]# getenforce
Enforcing
|
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
|
[root@localhost ~]# gedit /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
|
[root@localhost ~]# gedit /boot/grub/menu.lst
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
