以下笔记为简略记录，详细实战内容待补充。

【下载，解压安装zookeeper】

http://archive.cloudera.com/cdh5/

【配置zookeeper】

dataDir=/opt/modules/zookeeper-3.4.5-cdh5.10.0/zkData

server.1=data1.zeal.name:2888:3888

server.2=data2.zeal.name:2888:3888

server.3=data3.zeal.name:2888:3888

[zeal@data1 zkData]$ touch myid

[zeal@data1 zkData]$ vi myid

【启动zoo服务】

[zeal@data3 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh start

[zeal@data2 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh start

[zeal@data1 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh start

JMX enabled by default

Using config: /opt/modules/zookeeper-3.4.5-cdh5.10.0/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

[zeal@data1 zookeeper-3.4.5-cdh5.10.0]$ jps

2350 Jps

2332 QuorumPeerMain

[zeal@data1 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh status

JMX enabled by default

Using config: /opt/modules/zookeeper-3.4.5-cdh5.10.0/bin/../conf/zoo.cfg

Mode: follower

【客户端连接测试】

[zeal@data1 zookeeper-3.4.5-cdh5.10.0]$ bin/zkCli.sh

[zk: localhost:2181(CONNECTED) 0] ls /

[zookeeper]

[zk: localhost:2181(CONNECTED) 1] create /zeal zou

Created /zeal

[zk: localhost:2181(CONNECTED) 2] ls /

[zeal, zookeeper]

[zk: localhost:2181(CONNECTED) 3] get /zeal

zou

[zk: localhost:2181(CONNECTED) 4] quit

补充：zookeeper集群部署遵循2n+1原则（n可损坏机器数量）

[zeal@data1 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh stop

[zeal@data2 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh stop

[zeal@data3 zookeeper-3.4.5-cdh5.10.0]$ bin/zkServer.sh stop
