# Docker快速安装Zookeeper #

> 换了公司后很久没用过`Zookeeper`，最近因为在搞`Elastic-Job`需要用到，这里简单记录下用`Docker`搭建过程，下一篇会讲解怎么快速搭建集群。这里不会细讲如何搭建`Docker`，如果想了解`Docker`的朋友可以查看我之前写的`Docker`系列文章。

## 运行Zookeeper ##

指定端口为`2181`,容器名称为`zookeeper`

evans-MacBook-Pro:tool evan$ docker run -d -p 2181:2181 --name zookeeper --restart always 50d238989423
    548d103dabaa3c453f48a55f8dfeb3d241a60ad27fe0f11a114534ae5464b3fe

## 查看Zookeeper容器ID ##

evans-MacBook-Pro:tool evan$ docker ps
    CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS                                                                     NAMES

## 通过容器ID进入Zookeeper ##

evans-MacBook-Pro:tool evan$ docker exec -it 548d103dabaa bash
    root@548d103dabaa:/apache-zookeeper-3.7.0-bin#

## 执行Zookeeper启动命令 ##

## 下载Zookeeper可视化控制台 ##

这里我随便在Github下了一个 ，供大家参考

https://github.com/hellosix/zookeeper-manager/archive/refs/heads/master.zip

## 运行Zookeeper-manager代码 ##

导入`IDEA`，直接启动`ZookeeperManagerApplication`，默认端口是8081

## 连接Zookeeper服务 ##

这里添加一个新的服务，输入`127.0.0.1:2181`
