1、下載zookeeper-3.4.10.tar.gz
2、解壓縮zookeeper-3.4.10.tar.gz
#tar xvf zookeeper-3.4.10.tar.gz
3、配置zookeeper
將以下內容寫入到/opt/hadoop/zookeeper-3.4.10/bin/../conf/zoo.cfg
initLimit=10
syncLimit=5
dataDir=/opt/hadoop/zookeeper-3.4.10/
clientPort=2181
autopurge.snapRetainCount=3
autopurge.purgeInterval=1
server.1=nnnode1:2888:3888
server.2=nnnode2:2888:3888
server.3=nnnode3:2888:3888
將/opt/hadoop/zookeeper-3.4.10/bin/../conf/zoo.cfg文件複製到另外兩臺機器
4、在每臺服務器上設置myid
5、啓動zookeeper
在每臺機器上執行如下命令
#bash /opt/hadoop/zookeeper-3.4.10/bin/zkServer.sh start
6、查看狀態
在每臺機器上執行如下命令
#bash /opt/hadoop/zookeeper-3.4.10/bin/zkServer.sh status
出現如下信息說明啓動成功
ZooKeeper JMX enabled by default
Using config: /opt/hadoop/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: leader
7、停止zookeeper
#bash /opt/hadoop/zookeeper-3.4.10/bin/zkServer.sh stop
