下載穩定版Zookeeper

https://downloads.apache.org/zookeeper/stable/

GZ包：

apache-zookeeper-3.6.3-bin.tar.gz 

解壓一份到本地磁碟中

1、將conf目錄下的zoo_sample.cfg複製一份改名為zoo.cfg

2、更改zoo.cfg的配置

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit
 
=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:\\develop\\ZookeeperCluster\\apache-zookeeper-3.5.9-2\\data
# the port at 
 
which the clients will connect
clientPort=2182
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
 

#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1 = 127.0.0.1:2184:3887
server.2 = 127.0.0.1:2185:3888
server.3 = 127.0.0.1:2186:3889

由於是在一臺機器上部署三個Zookeeper例項，必然佔用系統很多埠資源

每個例項的客戶埠不能一致，服務埠和選舉埠也不能一致

1個例項佔用 3個埠 （客戶埠 + 服務埠 + 選舉埠）

然後把Zookeeper的目錄複製2份出來，分別重新命名以區分

apache-zookeeper-3.5.9-1
apache-zookeeper-3.5.9-2
apache-zookeeper-3.5.9-3

寫入服務ID標識

ECHO 1 > apache-zookeeper-3.5.9-1\ZookeeperCluster\apache-zookeeper-3.5.9-1\data\myid
ECHO 2 > apache-zookeeper-3.5.9-1\ZookeeperCluster\apache-zookeeper-3.5.9-2\data\myid
ECHO 3 > apache-zookeeper-3.5.9-1\ZookeeperCluster\apache-zookeeper-3.5.9-3\data\myid

更改apache-zookeeper-3.5.9-2 的zoo.cfg 客戶端埠為 2182

更改apache-zookeeper-3.5.9-3 的zoo.cfg 客戶端埠為 2183

clientPort=2181
clientPort=2182
clientPort=2183

為了方便啟動，可以編寫叢集啟動指令碼:

@ECHO OFF
start %CD%\apache-zookeeper-3.5.9-1\bin\zkServer.cmd
start %CD%\apache-zookeeper-3.5.9-2\bin\zkServer.cmd
start %CD%\apache-zookeeper-3.5.9-3\bin\zkServer.cmd
