Docker环境下使用docker-compose一键式搭建RocketMQ（4.5.0版本）集群及其管理工具(内网版)

前言

本节我们主要讲解下如何使用docker-compose一键式搭建一套RocketMQ的消息中间键集群服务，在项目开发中kafka与rockerMQ应该是我们最常用的消息中间键，为了最大化的利用系统资源，便于研究测试，docker容器搭建这些应用服务应该是我们的不二选择。

• 创建docker-compose的rocketmq.yml启动脚本

  brokerClusterName = DefaultCluster
  #broker名称
  brokerName = rocketmq-broker-1
  brokerId = 0
  deleteWhen = 04
  fileReservedTime = 48
  brokerRole = ASYNC_MASTER
  flushDiskType = ASYNC_FLUSH
  

  本次我们搭建三台broker服务器，分别在宿主机卷映射目录下创建我们的配置文件

①/usr/local/bin/atp/rocketmq/conf/broker1/broker.conf

②/usr/local/bin/atp/rocketmq/conf/broker2/broker.conf

③/usr/local/bin/atp/rocketmq/conf/broker3/broker.conf

（1）创建配置文件目录，以broker1为例：

命令：mkdir -p /usr/local/bin/atp/rocketmq/conf/broker1

（2）使用vi编辑器创建broker配置文件broker.conf，只需更改服务器名称即可

• 启动集群

命令：docker-compose -f rocketmq.yml -p rocketmq up -d

• 验证集群

访问控制台：http//ip:9090
