zookeeper-3.4.10-1 、zookeeper-3.4.10-2与zookeeper-3.4.10-0类似，只有dataDir和dataLogDir配置到不同的目录，clientPort在zookeeper-3.4.10-0中是2181，在zookeeper-3.4.10-1中是 2182，在 zookeeper-3.4.10-2中为 2183
       在之前设置的dataDir中新建myid文件, 写入一个数字, 该数字表示这是第几号server. 该数字必须和zoo.cfg文件中的server.X中的X一一对应.
D:/JAVA/zookeeper-3.4.10-0/data/myid文件中写入0，zookeeper-3.4.10-1为1，zookeeper-3.4.10-2为2

 server.A=B：C：D：其中
 A 是一个数字，表示这个是第几号服务器;
B 是这个服务器的 ip 地址;
C 表示的是这个服务器与集群中的 Leader 服务器交换信息的端口;
D 表示的是万一集群中的 Leader 服务器挂了，需要一个端口来重新进行选举，选出一个新的 Leader，而这个端口就是用来执行选举时服务器相互通信的端口。
如果是伪集群的配置方式，由于 B 都是一样，所以不同的 Zookeeper 实例通信端口号不能一样，所以要给它们分配不同的端口号。

部署了3台zookeeper server, 分别部署在10.1.39.43, 10.1.39.47, 10.1.39.48上. 需要注意的是, 各server的dataDir目录下的myid文件中的数字必须不同.

10.1.39.43 server的myid为43, 10.1.39.47 server的myid为47, 10.1.39.48 server的myid为48.
