ZooKeeper 集群环境搭建 （本机3个节点）

--------------------------------------------------------
1、建立目录
server1
server1/dataDir
server1/dataLogDir
server1/logs
server1/zookeeper3.4.6

server2
server2/dataDir
server2/dataLogDir
server2/logs
server2/zookeeper3.4.6

server3
server3/dataDir
server3/dataLogDir
server3/logs
server3/zookeeper3.4.6

-------------------------------------------------------
2、myid

server1/dataDir/myid
1

server2/dataDir/myid
2

server3/dataDir/myid
3

--------------------------------------------------------
3、zoo.cfg

server1/dataDir/zookeeper3.4.6/conf/zoo.cfg

tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:/Tools/zookeeper3.4.6/server1/dataDir
dataLogDir=D:/Tools/zookeeper3.4.6/server1/dataLogDir
clientPort=2181
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889

server2/dataDir/zookeeper3.4.6/conf/zoo.cfg
