下载地址

http://apache.dataguru.cn/zookeeper/zookeeper-3.4.7/zookeeper-3.4.7.tar.gz

如果慢或者打不开，可以到apache-zookeeper-download找不同的资源下载想要的版本

一、安装

tar zxvf /data/package/zookeeper-3.4.7.tar.gz -C /usr/local/

二、配置

cd /usr/local/zookeeper-3.4.7

1.配置文件

默认读取的是zoo.cfg

$ cat conf/zoo.cfg 

dataDir=/data/zookeeper
dataLogDir=/data/logs/zookeeper
clientPort=2181
maxClientCnxns=0

initLimit=5
syncLimit=2
tickTime=2000

server.1=n12:2888:3888
server.2=n13:2888:3888
server.3=n14:2888:3888

2.创建目录&id file

mkdir -p /data/zookeeper
echo "1" > /data/zookeeper/myid #三个节点唯一不同的就是这个id文件,对应server-id即可

3.启动zookeeper

bin/zkServer.sh start

三、测试

1.连接

bin/zkCli.sh -server 127.0.0.1:2181

2.简单操作

        get path [watch]
        ls path [watch]
        set path data [version]
