1.上傳安裝包並解壓

tar -zxvf zookeeper.jar -C app

2.修改配置檔案/home/chen/app/zookeeper-3.4.10/conf/zoo.cfg

# The number of tLimit=10syncLimit=5dataDir=/tmp/zookeepermilliseconds of each tick
tickTime=2000  //心跳節奏，兩秒一次
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10 // 初始化時間
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5 //心跳應答時間
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/home/chen/app/zookeeper-3.4.10/zoodata  //資料儲存
# the port at which the clients will connect
clientPort=2181  //

server.1=hadoop102:2888:3888   //節點配置，2888是主從節點通訊埠，3888是選舉埠
server.2=hadoop103:2888:3888
server.3=hadoop104:2888:3888
# 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
 

3.在每個節點的data目錄建立一個myid檔案，檔案裡寫上自己的id號。

echo 1 > myid

4.分發資料

scp  -r zookeeper hadoop101:/home/chen/app

5.在每個子節點重複步驟3
6.啟動節點

sh /home/chen/app/zookeeper-3.4.10/bin/zkServer.sh start

7.檢查節點狀態

 sh /home/chen/app/zookeeper-3.4.10/bin/zkServer.sh status

記得關閉防火牆
