#  Spring Cloud Alibaba 异步通信 - 基于 Docker 安装 RocketMQ

## docker-compose.yml

**注意：启动 RocketMQ Server + Broker + Console 至少需要 2G 内存**

```yaml
version: '3.5'
services:
  rmqnamesrv:
    image: foxiswho/rocketmq:server
    container_name: rmqnamesrv
    ports:
      - 9876:9876
    volumes:
      - ./data/logs:/opt/logs
      - ./data/store:/opt/store
    networks:
        rmq:
          aliases:
            - rmqnamesrv

rmqbroker:
    image: foxiswho/rocketmq:broker
    container_name: rmqbroker
    ports:
      - 10909:10909
      - 10911:10911
    volumes:
      - ./data/logs:/opt/logs
      - ./data/store:/opt/store
      - ./data/brokerconf/broker.conf:/etc/rocketmq/broker.conf
    environment:
        NAMESRV_ADDR: "rmqnamesrv:9876"
        JAVA_OPTS: " -Duser.home=/opt"
        JAVA_OPT_EXT: "-server -Xms128m -Xmx128m -Xmn128m"
    command: mqbroker -c /etc/rocketmq/broker.conf
    depends_on:
      - rmqnamesrv
    networks:
      rmq:
        aliases:
          - rmqbroker

rmqconsole:
    image: styletang/rocketmq-console-ng
    container_name: rmqconsole
    ports:
      - 8080:8080
    environment:
        JAVA_OPTS: "-Drocketmq.namesrv.addr=rmqnamesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false"
    depends_on:
      - rmqnamesrv
    networks:
      rmq:
        aliases:
          - rmqconsole

networks:
  rmq:
    name: rmq
    driver: bridge
```

## broker.conf

RocketMQ Broker 需要一个配置文件，按照上面的 Compose 配置，我们需要在 `./data/brokerconf/` 目录下创建一个名为 `broker.conf` 的配置文件，内容如下：

# 启动IP,如果 docker 报 com.alibaba.rocketmq.remoting.exception.RemotingConnectException: connect to <192.168.0.120:10909> failed
# 解决方式1 加上一句 producer.setVipChannelEnabled(false);，解决方式2 brokerIP1 设置宿主机IP，不要使用docker 内部IP
