+
+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
+```
+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
+
+```
+cd nacos-docker/image-build
+```
+
+执行脚本构建镜像，示例为 5.1.3 版本
+
+```
+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
+```
+sh build-image.sh 5.1.3 alpine
+```
+
+## rocketmq-dashboard镜像构建[可选]
+
+```
+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。
+
+{{< admonition question "404 Not Found" false >}} 
+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
+
+```
+mkdir -p /root/rocketmq/data/namesrv/logs
+mkdir -p /root/rocketmq/data/namesrv/store
+
+```
+
+### Broker的挂载路径
+
+```
+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
+
+```
+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
+
+```
+
+### 编写Docker-compose文件
+
+```
+version: '3'
+services:
+  #Service for nameserver
+  namesrv:
+    image: apache/rocketmq:5.1.3
+    container_name: rocketmq-namesrv
+    ports:
+      - 9876:9876
+    environment:
+      - JAVA_OPT_EXT=-server -Xms256m -Xmx256m -Xmn256m
+    volumes:
+      - /root/rocketmq/data/namesrv/logs:/root/logs
+      - /root/rocketmq/data/namesrv/store:/home/rocketmq/store
+    command: sh mqnamesrv
+
+  #Service for broker
+  broker:
+    image: apache/rocketmq:5.1.3
+    container_name: rocketmq-broker
+    links:
+      - namesrv
+    depends_on:
+      - namesrv
+    ports:
+      - 10909:10909
+      - 10911:10911
+      - 10912:10912
+    environment:
+      - NAMESRV_ADDR=namesrv:9876
+      - JAVA_OPT_EXT=-server -Xms512m -Xmx512m -Xmn256m
+    volumes:
+      - /root/rocketmq/data/broker/logs:/home/rocketmq/logs
+      - /root/rocketmq/data/broker/store:/home/rocketmq/store
+      - /root/rocketmq/etc/broker/broker.conf:/home/rocketmq/conf/broker.conf
+    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
+
+```
+docker-compose -f ./docker-compose.yml up
+```
+
+启动成功后，可以访问 `localhost:8080`查看 dashboard。
+
+{{< admonition note "compose文件注意事项">}} 
+
+1. image: apache/rocketmq:5.1.3 镜像名字正确
+2. volumes: 挂载路径保证一致
+      - /root/rocketmq/data/namesrv/logs:/root/logs
