RocketMQ在linux下安裝部署

本博客以當前RocketMQ最新版介紹：v4.4.0

環境要求

1. 64位JDK 1.8+;
2. Maven 3.2.x; // 源碼編譯時需要用到

二進制文件安裝

1. 下載二進制文件：http://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/4.4.0/rocketmq-all-4.4.0-bin-release.zip
2. 二進制文件放到任意目錄（由於是純凈的ubuntu鏡像，docker環境，因此我放在/root/xxx目錄下）
3. 解壓zip包，並重命名文件名

> unzip  rocketmq-all-4.4.0-bin-release.zip && mv rocketmq-all-4.4.0-bin-release rocketmq

4. 啟動server

> cd /root/rocketmq
> nohup sh bin/mqnamesrv & // 第一次安裝時，可執行sh bin/mqnamesrv觀察是否能夠啟動
> tailf -f ~/logs/rocketmqlogs/namesrv.log 
// 觀察到以下日志時，server已啟動成功
2019-09-07 18:06:13 INFO main - The Name Server boot success. serializeType=JSON

5. 啟動broker

> nohup sh bin/mqbroker -n localhost:9876
> tailf -f ~/logs/rocketmqlogs/broker.log 
// 觀察到以下日志時，server已啟動成功
2019-09-07 20:40:06 INFO main - The broker[0daf9bd41237, 172.17.0.2:10911] boot success. serializeType=JSON and name server is 172.17.0.2:9876

注：broker啟動如果過一會直接退出，無任何日志或報錯的話，檢查一下機子的內存是否充足。RocketMQ的broker默認內存為8g。
修改文件：/root/rocketmq/bin/runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m"

6. 測試生產者和消費者

// 在測試之前，我們需要先設置環境變量：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...

Producer的源碼

public class Producer {
    public static void main(String[] args) throws MQClientException, InterruptedException {
		// 默認消費組
        DefaultMQProducer producer = new DefaultMQProducer("default");

        producer.start();

        for (int i = 0; i < 1000; i++) {
            try {
                Message msg = new Message("TopicTest" /* Topic */,
                    "TagA" /* Tag */,
                    ("Hello RocketMQ " + i).getBytes(RemotingHelper.DEFAULT_CHARSET) /* Message body */
                );
                // 消息發送
                SendResult sendResult = producer.send(msg);
                System.out.printf("%s%n", sendResult);
            } catch (Exception e) {
                e.printStackTrace();
                Thread.sleep(1000);
            }
        }
		// 關閉生產者
        producer.shutdown();
    }
}

Consumer的源碼

public class Consumer {

    public static void main(String[] args) throws InterruptedException, MQClientException {
		// 指定消費組
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("default");
       // 設置消費偏移點
        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);
		// 訂閱topic，以及tag
        consumer.subscribe("TopicTest", "*");
		// 注冊消息監聽器
        consumer.registerMessageListener(new MessageListenerConcurrently() {

            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs,
                ConsumeConcurrentlyContext context) {
                System.out.printf("%s Receive New Messages: %s %n", Thread.currentThread().getName(), msgs);
                // 收到數據后，返回ack確認
				return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });
        consumer.start();

        System.out.printf("Consumer Started.%n");
    }
}

7. 關閉server和broker

> sh bin/mqshutdown broker
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

> sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK
