折腾Docker之RocketMQ单机部署

2023-07-27 约 909 字预计阅读 2 分钟

有不少教程是下载apache/rocketmq这个官方镜像来操作，由于本人新手，并且是单机运行，所以使用了官方提供的脚本，自己构建镜像运行。 (好像自己构建镜像更复杂了？😅)

本机环境 Mac

clone rocketmq-docker项目的代码

官方的docker地址

1
git clone https://github.com/apache/rocketmq-docker.git

执行命令下载官方的脚本仓库

rocketmq镜像构建

下载完成后，进入 nacos-docker/image-build 目录

1
cd nacos-docker/image-build

执行脚本构建镜像，示例为 5.1.3 版本

1
sh build-image.sh 5.1.3 centos

上面使用centos系统，最后出来的镜像比较大，可以选择 alpine，小很多

1
sh build-image.sh 5.1.3 alpine

rocketmq-dashboard镜像构建[可选]

1
sh build-image-dashboard.sh 1.0.0 centos

目前为止，dashboard的版本和系统是固定参数，传其他版本和系统会报错。

404 Not Found

这个问题是在下载https://dlcdn.apache.org/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz 文件时，找不到导致的错误

打开image-build目录下的Dockerfile-centos-dashboard文件，修改其中的MAVEN_VERSION=3.6.3的版本号，改成3.9.3

创建挂载路径

因为系统不同，路径也有所区别，只要保证路径正确存在就行

NameSrv的挂载路径

1
2
mkdir -p /root/rocketmq/data/namesrv/logs
mkdir -p /root/rocketmq/data/namesrv/store

Broker的挂载路径

1
2
3
mkdir -p /root/rocketmq/data/broker/logs
mkdir -p /root/rocketmq/data/broker/store
mkdir -p /root/rocketmq/etc/broker

创建Broker配置文件

1
nano /root/rocketmq/etc/broker/broker.conf

文件内容如下

brokerClusterName = mxsm-docker
brokerName = mxsm-docker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
# Docker环境需要设置成宿主机IP
brokerIP1 = 192.168.43.128

  #Service for nameserver

    command: sh mqbroker -c /home/rocketmq/conf/broker.conf

  # 如果前面没有创建dashboard的镜像，下面删除掉
  #Service for rocketmq-dashboard
  dashboard:
    image: apache/rocketmq-dashboard:1.0.0-centos
    container_name: rocketmq-dashboard
    ports:
      - 8080:8080
    links:
      - namesrv
    depends_on:
      - namesrv
    environment:
      - NAMESRV_ADDR=namesrv:9876

运行命令

1
docker-compose -f ./docker-compose.yml up

启动成功后，可以访问 localhost:8080查看 dashboard。

compose文件注意事项

image: apache/rocketmq:5.1.3 镜像名字正确
volumes: 挂载路径保证一致
- /root/rocketmq/data/namesrv/logs:/root/logs
