RocketMQ安装-Docker版本

本文针对对于想了解RocketMQ本质的同学，如何快速的在本地搭建一套本地环境。

部署服务

部署NameServer

docker pull rocketmqinc/rocketmq
docker run --name rmqnamesrv -d -p 9876:9876 rocketmqinc/rocketmq:4.4.0 sh mqnamesrv

部署Broker

• 启动脚本

docker run --name rmqbroker -d -p 10911:10911 -p 10909:10909 -v ./conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" rocketmqinc/rocketmq:4.4.0 sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf

borker.conf文件内容

brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
brokerIP1 = 30.203.94.18

注：重点修改brokerIP1的值，此值为宿主机的真实ip

部署RocketMQ可视化界面控制台

• 下载镜像

docker pull pangliang/rocketmq-console-ng

• 启动容器

docker run --name rmqconsole -d -p 8080:8080 --link rmqnamesrv:namesrv -e "JAVA_OPTS=-Drocketmq.namesrv.addr=namesrv:9876"  pangliang/rocketmq-console-ng

测试程序

生成者端

• 生成标准spring boot工程，可自行参考任意spring boot的创建（此处省略）
• 配置依赖

    org.apache.rocketmq
    rocketmq-spring-boot-starter
    2.1.1

• 配置application.properties

rocketmq.name-server=127.0.0.1:9876
rocketmq.producer.group=boot-group1
rocketmq.producer.sendMessageTimeout=300000

• 定义消息体

package com.example.producer;

import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
public class Demo01Message {
    public static final String TOPIC = "DEMO_01";
    private Integer id;
}

• 定义发送体

@Autowired
private RocketMQTemplate rocketMQTemplate;

@GetMapping("/send")
public String send() {
    Demo01Message message = new Demo01Message();
    message.setId(88899);
    rocketMQTemplate.syncSend(Demo01Message.TOPIC, message);
    return "send";
}

消费者端

• 生成标准spring boot工程，可自行参考任意spring boot的创建（此处省略）
• 配置依赖

    org.apache.rocketmq
    rocketmq-spring-boot-starter
    2.1.1

• 配置application.properties

rocketmq.name-server=127.0.0.1:9876

备注：

• 定义消息体

package com.example.producer;

import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
public class Demo01Message {
    public static final String TOPIC = "DEMO_01";
    private Integer id;
}

• 实现消息接受

@Service
@RocketMQMessageListener(
    topic = Demo01Message.TOPIC,
    consumerGroup = "my-consumer_test-topic-1"
)
public class MyConsumer implements RocketMQListener {

    @Override
    public void onMessage(Demo01Message demo01Message) {
        System.out.println(demo01Message);
    }
}
