mkdir rocketmq/logs
mkdir rocketmq/data
mkdir rocketmq/conf不小心建错使用下面命令删除rm -rf 文件夹名称 2、在conf文件夹下建立broker.conf文件vim broker.confbroker.conf的内容可以从这里复制https://github.com/apache/rocketmq/blob/master/distribution/conf/broker.conf# Licensed to the Apache Software Foundation (ASF) under one or more

flushDiskType ASYNC_FLUSH说明我们之所以要建立broker.conf文件是因为我们需要通过这个文件把RocketMQ管理起来,尽管我们可以暂时什么都不做3、在rocketmq文件夹中建立docker-compose.yml文件vim docker-compose.ymlversion: 3.8services:rmqnamesrv:image: apache/rocketmq:latestcontainer_name: rmqnamesrvports:- 9876:9876volumes:- /usr/local/rocketmq/logs:/home/rocketmq/logsenvironment:JAVA_OPT_EXT: -Duser.home/home/rocketmq -Xms256M -Xmx256M -Xmn128mcommand: [sh,mqnamesrv]broker:image: apache/rocketmq:latestcontainer_name: rmqbrokerports:- 10909:10909- 10911:10911volumes:- /usr/local/rocketmq/logs:/root/logs- /usr/local/rocketmq/store:/root/store- /usr/local/rocketmq/conf/broker.conf:/home/rocketmq/broker.conflinks:- rmqnamesrv:namesrv#restart: alwaysdepends_on:- rmqnamesrvenvironment:NAMESRV_ADDR: namesrv:9876JAVA_OPT_EXT: -Duser.home/home/rocketmq -Xms256M -Xmx256M -Xmn128mcommand: [sh,mqbroker,-c,/home/rocketmq/broker.conf,autoCreateTopicEnabletrue]rmqdashboard:image: apacherocketmq/rocketmq-dashboard:latestcontainer_name: rocketmq-dashboardports:- 8082:8080environment:JAVA_OPTS: -Drocketmq.namesrv.addrnamesrv:9876注意volumes参数的映射规则是 : 冒号前面是宿主机的文件夹和文件路径冒号后面是容器内的路径。在配置broker的volumes时容器内的路径一定要用root开头否则会导致broker启动的时候一直退出查看日志也没有任何信息只能在docker-compose up的时候看见rmqbroker exited with code 253说明apacherocketmq/rocketmq-dashboard:latest这个镜像是控制台的镜像在docker-compose中配置好之后启动时会自动下载其实所有镜像配置完成后在启动时都会校验没有则自动下载启动docker-compose up -d # “ -d ” 指后台运行想看启动时的日志可以不用加成功结尾附加几个docker-compose常用的命令如果配置有问题方便删除重新构建验证编写的docker-compose.yml 是否正确 docker-compose build或者docker-compose config -g停止docker-compose运行的镜像docker-compose stop停止并删除docker-compose运行的镜像docker-compose down删除docker-compose发布的容器docker-compose rm
