CentOS 6.9：ntpdate[3115]: no server suitable for synchronization found

CentOS 6.9：ntpdate[3115]: no server suitable for synchronization found

在做一个集群实验，克隆的虚拟机，然后使用ntpdate就抛出了错误。机器之间可以互相ping通，selinux和iptables都已经关闭。

[root@Server_2 ~]# service ntpd stop
Shutting down ntpd: [ OK ]
[root@Server_2 ~]# ntpdate Server_1
17 Apr 21:30:18 ntpdate[3113]: no server suitable for synchronization found

[root@Server_2 ~]# ntpdate -d Server_1

折腾了差不多20分钟，悲吹的结局是重启了下机器，然后什么都没有做，又好了。

[root@Server_2 ~]# ntpdate Server_1
