1、先安装hadoop，详见hadoop安装部署

2、下载安装包 zookeeper-3.4.5 解压到hadoop目录

3、编辑 vim /etc/profile 导入

export ZK_HOME=/data/hadoop272/zookeeper
export PATH=${ZK_HOME}/bin:$PATH

source /etc/profile

4、进入zookeeper/conf目录，复制zoo_sample.cfg改名zoo.cfg

cp zoo_sample.cfg zoo.cfg

5、编辑 vim zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/hadoop272/zookeeper/data
clientPort=2181

server.1=Slave1:2888:3888
server.2=Slave2:2888:3888
server.3=Master:2888:3888

6、修改 data/myid 与 server.x对应
