在本地虚拟机运行的完全正确，但是通过阿里云服务器链接，zeekeeper启动成功，但是查看zeekeeper状态的时候，却显示

  1. ZooKeeper JMX enabled by default
  2. Using config: /usr/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
  3. Error contacting service. It is probably not running.

查看zookeeper日志，发现拒绝访问，就是上面的一团。

本来以为是三台主机没有配置好，重装了好几次，最后总结了4个问题。

1：如果用阿里云服务器，链接，服务器没有防火墙，只有安全组，需要自己开放端口。（这次悲剧这里）

2：在本地进行连接的话 127.0.0.1配置注销了（很多博主都写了，我也不知道为啥）

3：记着设置为静态路由，动态的，修改比较麻烦。

4：zookeeper的原子广播协议（选举算法），将集群分为leader（有且只有一个），和follower，这些是从众多结点中随机选出，需要每一个结点的zookeeper都要开启，不然也会造成链接失败。（注：有的时候选举的特别慢，要耐心等候，不然容易ε(┬┬﹏┬┬)3）
