关闭SELinux

前言

最近换了CentOS6.X,多台主机之间相互打通SSH密钥之后,发现SSH/SCP命令依然需要输入passwd

是SELinux的问题，关闭SELinux即可解决问题，RHEL6.X 默认是开启状态

1.查看SELinux状态

[root@duangr-1 ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted

2.暂时关闭，警告模式（重启后恢复）

[root@duangr-1 ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted

3.永久关闭（需要重启）

[root@duangr-1 ~] #  vi /etc/selinux/config
# 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

4.重启后查看SELinux状态

[root@duangr-1 ~]# sestatus
SELinux status:                 disabled
