# 使用docker安装RocketMQ #

> [官网地址][Link 1]

## 1、下载 ##

# git clone https://github.com/apache/rocketmq-docker.git
    # cd rocketmq-docker/
    # ls
    CONTRIBUTING.md  image-build  LICENSE  NOTICE  product  README.md  stage.sh  templates
    # cd image-build/
    # ls
    build-image.sh  Dockerfile-alpine  Dockerfile-centos  scripts  update.sh

## 2、创建RocketMQ镜像 ##

> 构建命令： `sh build-image.sh RMQ-VERSION BASE-IMAGE`  
> 可选[RMQ-VERSION][]

我们使用 4.7.1 alpine

➜  image-build git:(master)  sh build-image.sh 4.7.1 alpine
    Version = 4.7.1
    Sending build context to Docker daemon  27.14kB
    Step 1/22 : FROM openjdk:8-alpine
     ---> a3562aa0b991
    
    //..........构建时间较长请耐心等待
    
    //构建完成
    Successfully built 128108c2e50d
    Successfully tagged apacherocketmq/rocketmq:4.7.1-alpine

构建完成后，我们就能查询到镜像

# docker images |grep mq
    apacherocketmq/rocketmq  4.7.1-alpine   128108c2e50d     4   9 seconds ago      145MB

## 生成配置 ##

# cd ..
    # ls
    CONTRIBUTING.md  image-build  LICENSE  NOTICE  product  README.md  stage.sh  templates
    # sh stage.sh 4.7.1 (这里的4.7.1对应之前的镜像版本)
    Stage version = 4.7.1
    mkdir /root/rocketmq/rocketmq-docker/stages/4.7.1
    staged templates into folder /root/rocketmq/rocketmq-docker/stages/4.7.1
    # ls
    CONTRIBUTING.md  image-build  LICENSE  NOTICE  product  README.md  stages  stage.sh  templates

生成了stages目录，里面存放配置模板文件

# cd stages/
    # ls
    4.7.1
    # cd 4.7.1/
    # ls
    data            kubernetes        play-docker-compose.sh  play-docker.sh      play-kubernetes.sh  ssl
    docker-compose  play-consumer.sh  play-docker-dledger.sh  play-docker-tls.sh  play-producer.sh

部署方式有以下5种

1.  单机

./play-docker.sh alpine

1.  docker-composer

./play-docker-compose.sh

1.  kubernetes集群

./play-kubernetes.sh

1.  Cluster of Dledger storage(RocketMQ需要4.4.0版本以上)

./play-docker-dledger.sh

1.  TLS

./play-docker-tls.sh
    ./play-producer.sh
    ./play-consumer.sh

我这里选择的是单机部署，可以看到生成了两个容器

# docker ps |grep mq
    5b557ea1e6be        apacherocketmq/rocketmq:4.7.1-alpine                         "sh mqbroker"            25 seconds ago                                                                                      Up 24 seconds       0.0.0.0:10909->10909/tcp, 9876/tcp, 0.0.0.0:10911-10912->10911-10912/tcp   rmqbroker
    8b1318aee5d6        apacherocketmq/rocketmq:4.7.1-alpine                         "sh mqnamesrv"           26 seconds ago                                                                                      Up 25 seconds       10909/tcp, 0.0.0.0:9876->9876/tcp, 10911-10912/tcp                         rmqnamesrv

验证RocketMQ启动成功

1、使用命令 `docker ps|grep rmqbroker`找到RocketMQ broker的容器id

2、使用命令 `docker exec -it 5b557ea1e6be ./mqadmin clusterList -n nameserver_ip:9876` 验证RocketMQ broker工作正常

> nameserver\_ip请进入容器rmqnamesrv内部查看

# docker exec -it 5b557ea1e6be ./mqadmin clusterList -n 172.17.0.2:9876
    RocketMQLog:WARN No appenders could be found for logger (io.netty.util.internal.PlatformDependent0).
    RocketMQLog:WARN Please initialize the logger system properly.
    #Cluster Name #Broker Name #BID #Addr #Version #InTPS(LOAD) #OutTPS(LOAD) #PCWait(ms) #Hour #SPACE
    DefaultCluster    5b557ea1e6be            0     172.17.0.8:10911       V4_7_1                   0.00(0,0ms)         0.00(0,0ms)          0 447225.46 -1.0000

如需升级执行以下命令

cd image-build
    ./update.sh

## 安装RocketMQ控制台 ##

//拉取镜像
    docker pull apacherocketmq/rocketmq-console:2.0.0
    //运行容器，这里172.15.65.xx为宿主机ip
    docker run -e "JAVA_OPTS=-Drocketmq.namesrv.addr=172.15.65.xx:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -p 6881:8080 -t apacherocketmq/rocketmq-console:2.0.0

启动容器后可以通过 http://localhost:6881/\#/ 登录控制台

## golang client使用问题 ##

由于使用的docker服务启动，broker的地址是内网地址，需要将地址修改为外网地址

# docker ps |grep mq
    8abb966542a3        apacherocketmq/rocketmq-console:2.0.0                        "sh -c 'java $JAVA..."   17 hours ago        Up 17 hours         0.0.0.0:6881->8080/tcp                                                     dazzling_tesla
    5b557ea1e6be        apacherocketmq/rocketmq:4.7.1-alpine                         "sh mqbroker"            18 hours ago        Up 18 hours         0.0.0.0:10909->10909/tcp, 9876/tcp, 0.0.0.0:10911-10912->10911-10912/tcp   rmqbroker
    8b1318aee5d6        apacherocketmq/rocketmq:4.7.1-alpine                         "sh mqnamesrv"           18 hours ago        Up 18 hours         10909/tcp, 0.0.0.0:9876->9876/tcp, 10911-10912/tcp                         rmqnamesrv
    # docker exec -it 5b557ea1e6be bash // 进入到容器内部修改配置
    # vi ../conf/broker.conf

在文件中添加外网地址 `brokerIP1=172.15.65.xx`

    brokerClusterName = DefaultCluster
    brokerName = broker-a
    brokerId = 0
    deleteWhen = 04
    fileReservedTime = 48
    brokerRole = ASYNC_MASTER
    flushDiskType = ASYNC_FLUSH
    
    # add your IP
    brokerIP1=172.15.65.xx

然后重启broker, `docker restart 5b557ea1e6be`

> 这里需要去修改启动脚本 ./play-docker.sh 里的start\_namesrv\_broker() 函数中的docker启动命令，在mybroker后面添加-c …/conf/broker.conf

这样查看cluster会发现Address变成了外网地址。

## go中运行 ##

获取`go-client`：go get -u -v github.com/apache/rocketmq-client-go/v2@v2.0.0
