Centos中如何安装RocketMQ

小编给大家分享一下Centos中如何安装RocketMQ，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

安装

官方地址为：https://rocketmq.apache.org/docs/quick-start/ 本人安装如下：

//下载最新的rocketmq wget http://apache-mirror.8birdsvideo.com/rocketmq/4.4.0/rocketmq-all-4.4.0-bin-release.zip //解压 unzip rocketmq-all-4.4.0-bin-release.zip //切换到mq目录 cd rocketmq-all-4.4.0-bin-release //name server 启动 nohup ./bin/mqnamesrv -n 111.231.XX.XX:9876 & //-c conf/broker.conf autoCreateTopicEnable=true 参数需要带上，不然topic需要手动创建 nohup sh bin/mqbroker -n 111.231.XX.XX:9876 -c conf/broker.conf autoCreateTopicEnable=true &

配置,切换到mq的bin目录下

cd rocketmq-all-4.4.0-bin-release/bin

rocketmq默认最低内存为4g,机器内存不够用的话，找到runserver.sh和runbroker.sh编辑如下：

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

运行

运行官方demo，发现如下错误：

21:20:22.249 [NettyClientSelector_1] INFO  RocketmqRemoting - closeChannel: close the connection to remote address[] result: true org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException: sendDefaultImpl call timeout	at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendDefaultImpl(DefaultMQProducerImpl.java:640)	at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducerImpl.java:1310)	at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducerImpl.java:1256)	at org.apache.rocketmq.client.producer.DefaultMQProducer.send(DefaultMQProducer.java:339)	at org.apache.rocketmq.example.simple.Producer.main(Producer.java:40)

运行以下命令查看broker配置并写入远程ip地址：

//查看broker配置 sh ./bin/mqbroker -m //关闭broker sh bin/mqshutdown broker //将本机远程ip写入配置文件中 echo 'brokerIP1=111.231.XX.XX' > conf/broker.properties  //重新启动broker nohup sh bin/mqbroker -n 111.231.XX.XX:9876 -c conf/broker.conf autoCreateTopicEnable=true &

管理控制台安装

Git地址：https://github.com/apache/rocketmq-externals/tree/master/rocketmq-console

git clone git@github.com:apache/rocketmq-externals.git cd  rocketmq-external/rocketmq-console/ mvn clean package -Dmaven.test.skip=true

打完包后，运行以下命令

java -jar rocketmq-console-ng-1.0.1.jar --server.port=12181 --rocketmq.config.namesrvAddr=111.231.XX.XX:9876

打开 http://localhost:12181访问控制台，像如下 在Procuder这个页面查询时会出现如下异常：

java.lang.RuntimeException: org.apache.rocketmq.client.exception.MQBrokerException: CODE: 1  DESC: the producer group[] not exist For more information, please visit the url, http://rocketmq.apache.org/docs/faq/         at com.google.common.base.Throwables.propagate(Throwables.java:160)         at org.apache.rocketmq.console.service.impl.ProducerServiceImpl.getProducerConnection(ProducerServiceImpl.java:38)         at org.apache.rocketmq.console.controller.ProducerController.producerConnection(ProducerController.java:39)

请把代码中producer.shutdown()这句注掉，生产环境中请加上。

 //producer.shutdown();

代码示例（官方）

生产者

package org.apache.rocketmq.example.simple; 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.common.RemotingHelper; public class Producer {     public static void main(String[] args) throws MQClientException, InterruptedException {         DefaultMQProducer producer = new DefaultMQProducer("ProducerGroupName");         producer.setNamesrvAddr("111.231.XX.XX:9876");         producer.start();         for (int i = 0; i < 10; i++)             try {                 {                     Message msg = new Message("TopicTest",                         "TagA",                         "OrderID188",                         "Hello world".getBytes(RemotingHelper.DEFAULT_CHARSET));                     SendResult sendResult = producer.send(msg);                     System.out.printf("%s%n", sendResult);                 }             } catch (Exception e) {                 e.printStackTrace();             }         //producer.shutdown();     } }

消费者

package org.apache.rocketmq.example.simple; import java.util.List; 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; public class PushConsumer {     public static void main(String[] args) throws InterruptedException, MQClientException {         DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("CID_JODIE_1");         consumer.subscribe("TopicTest", "*");         consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);         //wrong time format 2017_0422_221800         //consumer.setConsumeTimestamp("20181109221800");         consumer.setNamesrvAddr("111.231.XX.XX:9876");         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);                 return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;             }         });         consumer.start();         System.out.printf("Consumer Started.%n");     } }
