确认防火墙和SELinux是禁用的
(以Node1为例，两个节点相同)
[root@12crac1 ~]# iptables -L
Chain INPUT (policy ACCEPT)
target? ? prot opt source? ? ? ? ? ? ? destination? ? ? ?
Chain FORWARD (policy ACCEPT)
target? ? prot opt source? ? ? ? ? ? ? destination? ? ? ?
Chain OUTPUT (policy ACCEPT)
target? ? prot opt source? ? ? ? ? ? ? destination?
如果防火墙没禁用，那么通过如下方式修改：
[root@12crac1 ~]# service iptables stop
[root@12crac1 ~]# chkconfig iptables off
[root@12crac1 ~]# getenforce
Disabled
如果SELinux没有被禁止，那就通过如下方式修改：
[root@12crac1 ~]# cat /etc/selinux/config
-- 改成SELINUX=disabled
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#? ? enforcing - SELinux security policy is enforced.
#? ? p
