集群3个几点
节点1配置

clientPort=6001
server.1=127.0.0.1:6002:6003
server.2=127.0.0.1:6012:6013
server.3=127.0.0.1:6022:6023

server.id=IP/Host:port1:port2
port1 Leader和Follower或Observer交换数据使用 ,leader才开启此端口
port2 用于Leader选举

org.apache.ZooKeeperService:name0=ReplicatedServer_id1
{QuorumSize=3}
集群共3个节点

org.apache.ZooKeeperService:name0=ReplicatedServer_id1,name1=replica.1	

{ElectionType=3, InitLimit=10, MaxClientCnxnsPerHost=60, MaxSessionTimeout=40000, MinSessionTimeout=4000, QuorumAddress=/127.0.0.1:6002, StartTime=Tue Sep 08 11:22:29 CST 2020, State=following, SyncLimit=5, Tick=0, TickTime=2000}
State=following 
following 状态  follow节点

org.apache.ZooKeeperService:name0=ReplicatedServer_id1,name1=replica.1,name2=Follower	
name2=Follower  说明 是 Follower 节点
{AvgRequestLatency=0, ClientPort=10.57.31.22:6001, ElectionTimeTaken=16103, LastQueuedZxid=0x1000001d2, MaxClientCnxnsPerHost=60, MaxRequestLatency=4, MaxSessionTimeout=40000, MinRequestLatency=0, MinSessionTimeout=4000, NumAliveConnections=4, OutstandingRequests=0, PacketsReceived=21359, PacketsSent=21366, PendingRevalidationCount=0, QuorumAddress=Socket[addr=localhost/127.0.0.1,port=6012,localport=8688], StartTime=Tue Sep 08 11:22:45 CST 2020, TickTime=2000, Version=3.4.10-39d3a4f269333c922ed3db283be479f9deacaa0f, built on 03/23/2017 10:13 GMT}
这里有很多重要的数据

ClientPort=10.57.31.22:6001  客户端接口
ElectionTimeTaken=16103
NumAliveConnections=4
PacketsReceived=21359, PacketsSent=21366

QuorumAddress=Socket[addr=localhost/127.0.0.1,port=6012,localport=8688]
