笔记：Mac上zookeeper的安装与启动

参照官方安装指南

下载压缩包

从 此地址 下载zookeeper-3.4.10.tar.gz

解压

> tar -zxvf zookeeper-3.4.10.tar.gz //解压
> cd zookeeper-3.4.10/conf //切换到配置目录下
> mv zoo_sample.cfg zoo.cfg //更改默认配置文件名称
> vi zoo.cfg //编辑配置文件，自定义dataDir

启动Server

> cd zookeeper-3.4.10/bin //切换到 bin目录
> ./zkServer.sh start //启动
ZooKeeper JMX enabled by default
Using config: zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

Cli连接

> cd zookeeper-3.4.10/bin //切换到 bin目录
> ./zkCli.sh -server 127.0.0.1:2181
[zk: 127.0.0.1:2181(CONNECTED) 0] help //输入help命令

停止Server

> ./zkServer.sh stop //停止后，如果CLi没有关闭，将报错
ZooKeeper JMX enabled by default
Using config: zookeeper-3.4.10/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED

配置文件说明

1. 文件名可以任意，不是非得改为zoo.cfg
2. tickTime: zookeeper中使用的基本时间单位, 毫秒
3. dataDir: 内存数据快照的保存目录；如果没有自定义Log也使用该目录
4. clientPort: 监听Cli连接的端口号
