1. 在根目录创建zookeeper文件夹（service1、service2、service3都创建）

\[root@localhost /\]\# mkdir zookeeper

通过Xshell上传文件到service1服务器：上传zookeeper-3.4.6.tar.gz到/software文件夹

2.远程copy将service1下的/software/zookeeper-3.4.6.tar.gz到service2、service3

\[root@localhost software\]\# scp -r /software/zookeeper-3.4.6.tar.gz root@192.168.2.212:/software/

\[root@localhost software\]\# scp -r /software/zookeeper-3.4.6.tar.gz root@192.168.2.213:/software/

3.copy /software/zookeeper-3.4.6.tar.gz到/zookeeper/目录（service1、service2、service3都执行）

\[root@localhost software\]\# cp /software/zookeeper-3.4.6.tar.gz /zookeeper/

4.安装解压zookeeper-3.4.6.tar.gz（service1、service2、service3都执行）

\[root@localhost /\]\# cd /zookeeper/

\[root@localhost zookeeper\]\# tar -zxvf zookeeper-3.4.6.tar.gz

5.在/zookeeper创建两个目录：zkdata、zkdatalog（service1、service2、service3都创建）

\[root@localhost zookeeper\]\# mkdir zkdata

\[root@localhost zookeeper\]\# mkdir zkdatalog

6.进入/zookeeper/zookeeper-3.4.6/conf/目录

\[root@localhost zookeeper\]\# cd /zookeeper/zookeeper-3.4.6/conf/

\[root@localhost conf\]\# ls

configuration.xsl  log4j.properties  zoo.cfg  zoo\_sample.cfg

7. 修改zoo.cfg文件

\# 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=/zookeeper/zkdata

dataLogDir=/zookeeper/zkdatalog

\# the port at which the clients will connect

clientPort=2181

\# 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.

\# 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=192.168.2.211:12888:13888

server.2=192.168.2.212:12888:13888

server.3=192.168.2.213:12888:13888

8. 同步修改service2、service3的zoo.cfg配置

9. myid文件写入（进入/zookeeper/zkdata目录下）

\[root@localhost /\]\# cd /zookeeper/zkdata

\[root@localhost /\]\# echo 1 > myid

10. myid文件写入service2、service3

echo 2 > myid

echo 3 > myid

11.查看zk命令：

\[root@localhost ~\]\# cd /zookeeper/zookeeper-3.4.6/bin/

\[root@localhost bin\]\# ls

README.txt  zkCleanup.sh  zkCli.cmd  zkCli.sh  zkEnv.cmd  zkEnv.sh  zkServer.cmd  zkServer.sh  zookeeper.out

12.执行zkServer.sh查看详细命令：

\[root@localhost bin\]\# ./zkServer.sh

JMX enabled by default

Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

Usage: ./zkServer.sh \{start|start-foreground|stop|restart|status|upgrade|print-cmd\}

13. 在service1、service2、service3分别启动zk服务

\[root@localhost bin\]\# ./zkServer.sh start

14. jps查看zk进程

\[root@localhost bin\]\# jps

31483 QuorumPeerMain

31664 Jps

15. 分别在service1、service2、service3查看zk状态（可以看到leader和follower节点）

\[root@localhost bin\]\# ./zkServer.sh status

JMX enabled by default

Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

Mode: follower

\[root@localhost bin\]\# ./zkServer.sh status

JMX enabled by default

Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

Mode: leader

16. 看到leader和follower节点已经安装成功
