zookeeper单机搭建

下载zookeeper

1	https://archive.apache.org/dist/zookeeper/zookeeper-3.4.13/

windows上安装

1.解压zookeeper-3.4.13.tar.gz

2.运行zkServer.cmd ，初次运行会报错，没有zoo.cfg配置文件
    D:\software\devlop_software\zookeeper-3.4.13\bin>zkServer.cmd
3.修改zoo.cfg配置文件
    将conf下的zoo_sample.cfg复制一份改名为zoo.cfg即可。
    注意几个重要位置：
    dataDir=./   临时数据存储的目录（可写相对路径）
    clientPort=2181   zookeeper的端口号
    修改完成后再次启动zookeeper

4.使用zkCli.cmd测试
    ls /：列出zookeeper根下保存的所有节点
    create –e /test 123：创建一个test节点，值为123
    get /test：获取/test节点的值

linux上安装
