最新版本下载页面：https://zookeeper.apache.org/releases.html
下载列表页面：https://archive.apache.org/dist/zookeeper/

说明

版本选择：apache-zookeeper-3.5.7-bin.tar.gz
下载地址：https://archive.apache.org/dist/zookeeper/zookeeper-3.5.7/apache-zookeeper-3.5.7-bin.tar.gz

安装前准备

在linux上安装，centos7上安装
安装java环境，参考：linux安装java -centos安装java -linux配置java环境变量

本地安装

复制下载的安装包到Linux服务器，安装包名：apache-zookeeper-3.5.7-bin.tar.gz
进入到安装包所在路径，将安装包解压到指定目录
shell 复制代码
```
tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C /opt/module
```
重命名，将apache-zookeeper-3.5.7-bin重命名为zookeeper-3.5.7
shell 复制代码
```
cd /opt/module
mv apache-zookeeper-3.5.7-bin/ zookeeper-3.5.7
```
复制配置zoo_sample.cfg文件并命名为zoo.cfg，默认加载的配置文件为zoo.cfg
shell 复制代码
```
cd /opt/module/zookeeper-3.5.7/conf/
cp zoo_sample.cfg zoo.cfg
```
在zookeeper根目录创建zkData文件夹，用来存放zookeeper数据，在配置文件中指定该路径
shell 复制代码
```
cd /opt/module/zookeeper-3.5.7
mkdir zkData
```

修改配置文件zoo.cfg

仅需要指定数据存储路径，其它可以保持不变

properties 复制代码

# dataDir=/tmp/zookeeper
dataDir=/opt/module/zookeeper-3.5.7/zkData

启动zookeeper服务端

启动zookeeper

shell 复制代码

cd /opt/module/zookeeper-3.5.7/bin
./zkServer.sh start

查看zookeeper进程，jps是java命令
shell 复制代码
```
jps -l
```
查看zookeeper状态
shell 复制代码
```
./zkServer.sh status
```
停止zookeeper
shell 复制代码
```
./zkServer.sh stop
```

启动zookeeper客户端

启动客户端，默认服务器为localhost
shell 复制代码
```
./zkCli.sh
```
输出信息：[zk: localhost:2181(CONNECTED) 0]
启动客户端，指定服务器
shell 复制代码
```
./zkCli.sh -server 192.168.145.132:2181
```
输出信息：[zk: 192.168.145.132:2181(CONNECTED) 0]
退出
shell 复制代码
```
quit
```
