ubuntu22.04 搭建RocketMQ

部署环境：

1. ubuntu22.04 
2. 64bit JDK 1.8+

一、 RocketMQ部署

1.1 下载

下载地址：https://rocketmq.apache.org/zh/download/

本文使用 4.9.8版本：

1.2 上传到指定目录下解压

unzip rocketmq-all-4.9.8-bin-release.zip

1.3 调整JVM参数

RocketMq默认的虚拟机内存较大，因而启动失败，需要编辑如下两个配置文件，修改jvm的内

 

//编辑runbroker.sh和runserver.sh修改默认的JVM大小
vim runbroker.sh
vim runserver.sh

 

 

1.3 启动RocketMQ

RocketMQ的启动主要涉及到Namesrv（命名服务）和Broker（消息存储和消费者服务）两部分，首先进入到bin路径下：

（1）启动Namesrv并设置输出日志位置：

nohup sh mqnamesrv > namesrv.log 2>&1 &

（2）启动Broker并设置输出日志位置

nohup sh mqbroker -n localhost:9876 > broker.log 2>&1 &

验证是否启动

jps

显示下面的内容说明启动成功了：

二、测试

（1）发送消息（生产者）

//设置环境变量
export NAMESRV_ADDR=localhost:9876
//使用安装包的demo发送消息，
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

成功示例：

（2） 接收消息（消费者）

//设置环境变量
export NAMESRV_ADDR=localhost:9876
//接收消息
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

成功示例：

 （3） 关闭RocketMQ

//关闭namesrv
sh bin/mqshutdown namesrv
//关闭Broker
sh bin/mqshutdown broker　

三、SpringBoot连接RocketMQ

3.1引入依赖

1 2 3 4 5 6 7 8 9 10

<dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-thymeleaf</artifactId>     <version>2.3.5.RELEASE</version> </dependency> <dependency>     <groupId>org.apache.rocketmq</groupId>     <artifactId>rocketmq-client</artifactId>     <version>4.5.2</version> </dependency>

3.2 添加配置 application.yml

1 2 3 4 5 6 7 8 9

rocketmq:   nameServer: your-nameserver-ip  # Name Server地址   producer:     group: "test_producer_group"# 生产者组名     topic: "test_topic"#订阅主题   consumer:     group: "test_consumer_group"# 消费者组名     topic: "test_topic"#订阅主题     subscription: "*"

3.3 创建生产者

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

importorg.apache.rocketmq.client.producer.DefaultMQProducer; importorg.springframework.beans.factory.annotation.Value; importorg.springframework.stereotype.Component; @Component publicclassRocketMQProducer {     @Value("${rocketmq.nameServer}")     privateString nameServer;     @Value("${rocketmq.producer.group}")     privateString producerGroup;     publicvoidsendMessage(String topic, String message) throwsException {         DefaultMQProducer producer = newDefaultMQProducer(producerGroup);         producer.setNamesrvAddr(nameServer);         producer.setSendMsgTimeout(6000);         producer.start();         // 创建消息对象，设置消息内容         org.apache.rocketmq.common.message.Message msg = neworg.apache.rocketmq.common.message.Message(topic, message.getBytes());         // 发送消息         producer.send(msg);         producer.shutdown();     } }

3.4 创建消费者　　

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

importorg.apache.rocketmq.client.consumer.DefaultMQPushConsumer; importorg.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus; importorg.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently; importorg.apache.rocketmq.client.exception.MQClientException; importorg.springframework.beans.factory.annotation.Value; importorg.springframework.stereotype.Component; @Component publicclassRocketMQConsumer {     @Value("${rocketmq.name-server}")     privateString nameServer;     @Value("${rocketmq.consumer.group}")     privateString consumerGroup;     publicvoidstartConsumer(String topic) throwsMQClientException {         DefaultMQPushConsumer consumer = newDefaultMQPushConsumer(consumerGroup);         consumer.setNamesrvAddr(nameServer);         // 订阅主题和标签，可以根据需要进行过滤         consumer.subscribe(topic, "*");         // 注册消息监听器         consumer.registerMessageListener((MessageListenerConcurrently) (msgs, context) -> {             for(org.apache.rocketmq.common.message.MessageExt msg : msgs) {                 System.out.println("Received message: "+ newString(msg.getBody()));             }             returnConsumeConcurrentlyStatus.CONSUME_SUCCESS;         });         consumer.start();     } }

3.5 创建测试启动类

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

importorder.rocketmq.RocketMQConsumer; importorder.rocketmq.RocketMQProducer; importorg.springframework.boot.SpringApplication; importorg.springframework.boot.autoconfigure.SpringBootApplication; importorg.springframework.context.ConfigurableApplicationContext; @SpringBootApplication publicclassRocketMQDemoApplication {     publicstaticvoidmain(String[] args) throwsException {         ConfigurableApplicationContext context = SpringApplication.run(RocketMQDemoApplication.class, args);         RocketMQProducer producer = context.getBean(RocketMQProducer.class);         producer.sendMessage("my-topic", "Hello, RocketMQ!");         RocketMQConsumer consumer = context.getBean(RocketMQConsumer.class);         consumer.startConsumer("my-topic");     } }

可以正常发送接收消息：
