RocketMQ-安装部署教程

前期准备

环境准备

Java8安装

Linux系统

安装包

rocketmq-4.2.0.zip（http://rocketmq.apache.org/dowloading/releases/）

Binary: rocketmq-all-4.2.0-bin-release.zip [PGP] [MD5] [SHA1]

安装

解压缩zip安装包到指定文件夹

unzip rocketmq-all-4.2.0-bin-release.zip -d rocketmq-4,2,0

部署

参考mq官方quickstart文档：http://rocketmq.apache.org/docs/quick-start/

启动Name Server

> nohup sh bin/mqnamesrv & > tail -f ~/logs/rocketmqlogs/namesrv.log The Name Server boot success...

注：启动过程中可能报错显示内存不足，报错信息如下：

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 33554432 bytes for committing 	     reserved memory.

需修改bin文件夹下的runserver.sh文件，改成

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:PermSize=128m -XX:MaxPermSize=320m"

xms：初始化内存 xmx：最大内存 xmn：新生代内存 permsize：永久区 maxPermSize：最大永久区

一般建议是按官方推荐的内存设置，否则可能发挥不出mq的性能。

同理，修改runbroker.sh文件，改成

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m

再同理，修改tools.sh文件，改成

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:PermSize=128m -XX:MaxPermSize=128m"

启动Broker

> nohup sh bin/mqbroker -n localhost:9876 autoCreateTopicEnable=true &
> tail -f ~/logs/rocketmqlogs/broker.log 
 The broker[%s, 172.30.30.233:10911] boot success...

注：官网上启动Broker用的命令就是nohup sh bin/mqbroker -n localhost:9876 & ，这样启动后在后来运行Producer发送的时候会出现

com.alibaba.rocketmq.client.exception.MQClientException: No route info of this topic, TopicTest1
See http://docs.aliyun.com/cn#/pub/ons/faq/exceptions&topic_not_exist for further details.
    at com.alibaba.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendDefaultImpl(DefaultMQProducerImpl.java:542)
  ...

autoCreateTopicEnable在broker配置文件里面默认是false，如果在配置文件里面改成true，就可以直接用nohup sh bin/mqbroker -n localhost:9876 &启动了。

发送&接收信息

在发送/接收消息之前，我们需要告诉客户端服务器的ip。RocketMQ提供了多种实现此目的的方法。为简单起见，我们使用环境变量namesrvaddr

> 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...

看见日志飞速刷，就是启动成功了。

关闭服务器

> 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

本地测试类

ProducerTest——生产者

public class ProducerTest {
    private static DefaultMQProducer producer = null;

    public static void main(String[] args) {
        System.out.print("[----------]Start");
        boolean result = false;
        try {
            ProducerStart();
            System.out.println("producer 启动成功");
            SendMessage("qch_20170706", "hello rocketmq!");
        }finally {
            producer.shutdown();
        }
        System.out.print("[----------]Succeed");
    }

    private static boolean ProducerStart() {
        producer = new DefaultMQProducer("pro_qch_test");
        producer.setNamesrvAddr("119.23.211.22:9876");
        producer.setInstanceName(UUID.randomUUID().toString());
        producer.setVipChannelEnabled(false);
        try {
            producer.start();
        } catch (MQClientException e) {
            e.printStackTrace();
            return false;
        }
        return true;
    }

    private static boolean SendMessage(String topic, String str) {
        Message msg = new Message(topic, str.getBytes());
        try {
            producer.send(msg);
        } catch (MQClientException | RemotingException | MQBrokerException | InterruptedException e) {
            e.printStackTrace();
            return false;
        }
        return true;
    }
}

ConsumerTest——消费者

public class ConsumerTest {
    public static void main(String[] args) {
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("con_qch_test");
        consumer.setInstanceName(UUID.randomUUID().toString());
        consumer.setConsumeMessageBatchMaxSize(32);
        consumer.setNamesrvAddr("119.23.211.22:9876");
        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);
        consumer.registerMessageListener(new MessageListenerConcurrently() {
            @Override
            public ConsumeConcurrentlyStatus consumeMessage(
                    List<MessageExt> list, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
                for(MessageExt me : list) {
                    System.out.print(new String(me.getBody()));
                }
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });
        try {
            consumer.subscribe("qch_20170706", "*");
            consumer.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

注：在本地启动的时候，可以会出现这个错误

需要在conf/broker.conf文件里面添加brokerIP1=你的服务器IP，然后启动broker的时候用

sh bin/mqbroker -n localhost:9876 autoCrenohup sh bin/mqbroker -n localhost:9876 autoCreateTopicEnable=true -c ~/software/rocketmq-4.2.0/conf/broker.conf &

看一下broker.log文件

2018-05-09 19:43:45 INFO main - load exist subscription group, SubscriptionGroupConfig [groupName=CID_ONS-HTTP-PROXY, consumeEnable=true, consumeFromMinEnable=true, consumeBroadcastEnable=true, retryQueueNums=1, retryMaxTimes=16, brokerId=0, whichBrokerWhenConsumeSlowly=1, notifyConsumerIdsChangedEnable=true]

2018-05-09 19:43:57 INFO BrokerControllerScheduledThread1 - register broker to name server localhost:9876 OK

再看一下nohup sh bin/mqbroker -n localhost:9876 autoCreateTopicEnable=true & 命令启动的broker的log日志

2018-05-09 19:39:02 INFO main - register broker to name server localhost:9876 OK
2018-05-09 19:39:02 INFO main - The broker[izwz9f1jdvkslcnjfonvbiz, 172.18.213.113:10911] boot success. serializeType=JSON and name server is localhost:9876

2018-05-09 19:39:12 INFO BrokerControllerScheduledThread1 - register broker to name server localhost:9876 OK

貌似多加载了config文件夹下的几个配置。

真是个深渊巨坑。。。。。。。。。。
