关闭SElinux
SELinux一共有3种状态
- Enforcing:强制模式。代表SELinux在运行中,且已经开始限制domain/type之间的验证关系
- Permissive:宽容模式。代表SELinux在运行中,不过不会限制domain/type之间的验证关系,即使验证不正确,进程仍可以对文件进行操作。不过如果验证不正确会发出警告
- Disabled:关闭模式。SELinux并没有实际运行
! 临时关闭SElinux
! 永久关闭SELinux
需修改配置文件:/etc/selinux/config
,修改 SELINUX=disabled。
1 [root@localhost ~]# cat /etc/selinux/config
2
3 # This file controls the state of SELinux on the system.
4 # SELINUX= can take one of these three values:
5 # enforcing - SELinux security policy is enforced.
6 # permissive - SELinux prints warnings instead of enforcing.
7 # disabled - No SELinux policy is loaded.
8 SELINUX=disabled #修改为disabled
9 # SELINUXTYPE= can take one of three two values:
10 # targeted - Targeted processes are protected,
11 # minimum - Modification of targeted policy. Only selected processes are protected.
12 # mls - Multi Level Security protection.
13 SELINUXTYPE=targeted
<<< 注意:修改SELinux永久关闭,必须重启服务器,才能生效。 <<<
永久关闭后,不能通过 setenforce 1 命令临时打开了
