Docker快速安装Zookeeper的详细教程

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。

搜索Zookeeper镜像

查询本地镜像

evans-MacBook-Pro:tool evan$ docker image ls

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

root@548d103dabaa:/apache-zookeeper-3.7.0-bin# ./bin/zkCli.sh

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
