本文详细介绍了如何在三台服务器上部署Zookeeper集群，包括环境需求、解压安装包、配置环境变量、设置配置文件、创建数据和日志文件夹、配置myid文件、分发软件、启动和检查集群状态等步骤。

一、环境需求

安装jdk

二、Zookeeper集群部署

1.解压安装包
[hadoop@hadoop01 tools]$ tar -zxvf zookeeper-3.4.10.tar.gz -C /home/hadoop/install/
2.修改名字
[hadoop@hadoop01 install]$ mv zookeeper-3.4.10/ zookeeper
3.配置环境变量
[hadoop@hadoop01 install]$ sudo vi /etc/profile

export PATH=$PATH:/home/hadoop/install/zookeeper/bin/

4.配置Zookeeper的配置文件
进入zookeeper的conf目录，修改配置文件名
[hadoop@hadoop01 conf]$ mv zoo_sample.cfg zoo.cfg
配置zoo.cfg
[hadoop@hadoop01 conf]$ vi zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataLogDir=/home/hadoop/install/zookeeper/logs
dataDir=/home/hadoop/install/zookeeper/data
clientPort=2181
autopurge.snapRetainCount=500
autopurge.purgeInterval=24
server.0= 192.168.75.128:2888:3888
server.1= 192.168.75.129:2888:3888
server.2= 192.168.75.130:2888:3888

5.在zookeeper目录下新建文件夹data和logs
[hadoop@hadoop01 zookeeper]$ mkdir data
[hadoop@hadoop01 zookeeper]$ mkdir logs

6.创建并配置myid
在data文件夹下创建一个文件，叫myid，并在文件中写入server.X对应的X
[hadoop@hadoop01 data]$ echo “0” > myid

7.分发zookeeper
[hadoop@hadoop01 data]$ xsync /home/hadoop/install/zookeeper/

8.在hadoop02、hadoop03中分别配置myid
[hadoop@hadoop02 data]$ vi myid
echo “1” > myid
[hadoop@hadoop03 data]$ vi myid
echo “2” > myid

9.在三个节点分别启动zookeeper
[hadoop@hadoop01 /]$ zkServer.sh start
[hadoop@hadoop02 /]$ zkServer.sh start
[hadoop@hadoop03 /]$ zkServer.sh start

10.查看状态
[hadoop@hadoop01 /]$ zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/hadoop/install/zookeeper/bin/…/conf/zoo.cfg
Mode: follower

[hadoop@hadoop02 ~]$ zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/hadoop/install/zookeeper/bin/…/conf/zoo.cfg
Mode: leader

[hadoop@hadoop03 /]$ zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/hadoop/install/zookeeper/bin/…/conf/zoo.cfg
Mode: follower
