RocketMQ部署

RocketMQ部署手册

单MasterRocketMQ集群

系统要求与准备条件

1. 64位操作系统，推荐 Linux/Unix/macOS

2. 64位 JDK 1.8+

3. Maven

   tips

   检验java环境与maven环境

   java -version

   

   mvn -v

下载安装Apache RocketMQ

RocketMQ 的安装包分为两种，二进制包和源码包，二进制包是已经编译完成后可以直接运行的，源码包是需要编译后运行的。

• rocketmq-all-5.0.0-ALPHA-bin-release.zip

  源码包直接解压

• rocketmq-all-5.0.0-ALPHA-source-release.zip

  二进制包使用maven编译

  $ unzip rocketmq-all-5.0.0-source-release.zip
  $ cd rocketmq-all-5.0.0-source-release/
  $ mvn -Prelease-all -DskipTests clean install -U
  $ cd distribution/target/rocketmq-5.0.0/rocketmq-5.0.0
  

启动NameServer

### 启动namesrv
$ nohup sh bin/mqnamesrv &
 
### 验证namesrv是否启动成功
$ tail -f ~/logs/rocketmqlogs/namesrv.log
The Name Server boot success...

我们可以在namesrv.log 中看到 'The Name Server boot success..'， 表示NameServer 已成功启动。

启动Broker

### 先启动broker
$ nohup sh bin/mqbroker -n localhost:9876 &

### 验证broker是否启动成功, 比如, broker的ip是192.168.1.2 然后名字是broker-a
$ tail -f ~/logs/rocketmqlogs/Broker.log 
The broker[broker-a,192.169.1.2:10911] boot success...

我们可以在 Broker.log 中看到“The broker[brokerName,ip:port] boot success..”，这表明 broker 已成功启动。

工具测试消息收发

在进行工具测试消息收发之前，我们需要告诉客户端NameServer的地址，RocketMQ有多种方式在客户端中设置NameServer地址，这里我们利用环境变量NAMESRV_ADDR

$ export NAMESRV_ADDR=localhost:9876
$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
 SendResult [sendStatus=SEND_OK, msgId= ...

$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
 ConsumeMessageThread_%d Receive New Messages: [MessageExt...

安装可视化控制台

1.下载项目

在 GitHub 中搜索 rocketmq-externals，其中 rocketmq-console 就是 RocketMQ 可视化控制台，我们可以将源码克隆下来，然后自己 mvn package，然后运行 jar 包。

或者直接下载官方提供的 1.0.0 版本的 rocketmq-console

https://github.com/apache/rocketmq-externals/releases/tag/rocketmq-console-1.0.0

下载 zip 包或者 tar 包

• 修改配置文件application.properties

  配置rocketmq.config.namesrvAddr属性的值，即nameserver的服务地址

  rocketmq.config.namesrvAddr=localhost:9876
  

• 保存修改后的配置文件，返回rocketmq-console目录

• 使用maven打包命令打包

  mvn clean package -Dmaven.test.skip=true
  

• 打包完成后进入target目录

rocketmq-console-ng-2.0.0.jar即为打包后得到的jar包

• 启动程序

  nohup java -jar rocketmq-console-ng-2.0.0.jar &
  

  

SDK测试消息收发

准备工作

启动 NameServer 和 broker

nohup sh bin/mqnamesrv >mqnamesrv-log.txt &

nohup sh bin/mqbroker -n 127.0.0.1:9876 >mqbroker-log.txt &

启动控制台

mvn spring-boot:run

创建一个 topic名为 test_quick_topic

工具测试完成后，我们可以尝试使用 SDK 收发消息。这里以 Java SDK 为例介绍一下消息收发过程。

• 在IDEA中创建一个Java工程。

• 在 pom.xml 文件中添加以下依赖引入Java依赖库。

    <dependencies>
        <dependency>
            <groupId>org.apache.rocketmqgroupId>
            <artifactId>rocketmq-clientartifactId>
            <version>4.9.4version>
        dependency>
        <dependency>
            <groupId>com.alibabagroupId>
            <artifactId>fastjsonartifactId>
            <version>2.0.13.graalversion>
        dependency>

生产者

• 同步投递10条消息

package TestProducer;
import org.apache.rocketmq.client.exception.MQBrokerException;
import org.apache.rocketmq.client.exception.MQClientException;
import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;
import org.apache.rocketmq.remoting.exception.RemotingException;
public class TestProducer01 {
    public static final String NAMESRV_ADDR = "127.0.0.1:9876";
    public static void main(String[] args) throws MQClientException, RemotingException, InterruptedException, MQBrokerException {
        DefaultMQProducer producer = new DefaultMQProducer("test_quick_producer_name");
        producer.setNamesrvAddr(NAMESRV_ADDR);
        producer.start();
        for (int i = 0; i <10; i++) {
            Message message = new Message("test_quick_topic",//主题
                    "tagA", //标签
                    "key" + i, //自定义key，唯一标识
                    ("第" + i+"次消息").getBytes()); //消息内容实体 (byte[])
            SendResult result = producer.send(message);
            System.out.println("第" + i + "条消息发出，结果：" + result);
        }
        producer.shutdown();
    }
}

消费者

• 消费上面生产者生产的10条消息

package TestConsumer;

import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer;
import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext;
import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus;
import org.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently;
import org.apache.rocketmq.client.exception.MQClientException;
import org.apache.rocketmq.common.consumer.ConsumeFromWhere;
import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.remoting.common.RemotingHelper;

import java.util.List;

public class TestConsumer01 {
    public static final String NAMESRV_ADDR = "127.0.0.1:9876";
    public static void main(String[] args) throws MQClientException {
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("test_quick_consumer_name");
        consumer.setNamesrvAddr(NAMESRV_ADDR);
        //从最后开始消费
        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_LAST_OFFSET);
//        consumer.subscribe("test_quick_topic","tagA"); //过滤：消费tag为tagA的消息
        consumer.subscribe("test_quick_topic", "*"); //消费所有的
        consumer.registerMessageListener(new MessageListenerConcurrently() {
            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List list, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
                MessageExt messageExt = list.get(0);
                try {
                    String topic = messageExt.getTopic();
                    String tags = messageExt.getTags();
                    String keys = messageExt.getKeys();
                    String msgBody = new String(messageExt.getBody(), RemotingHelper.DEFAULT_CHARSET);
                    System.out.println("topic: " + topic + ",tags: " + tags + ", keys: " + keys + ", body: " + msgBody);
                } catch (Exception e) {
                    e.printStackTrace();
                    return ConsumeConcurrentlyStatus.RECONSUME_LATER;
                }
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });
        consumer.start();
        System.out.println("comsumer start");
    }
}
