windows搭建RocketMQ服务

时间:2021-09-27 23:30:46

写在前面:
1、基于rocketmq 4.2.0版本
2、64位 win10 系统
3、JDK 1.8 (注意,jdk路径一定不要有空格,不然执行相应的cmd命令时会报错)
4、其它需要的软件,maven,git

一、下载二进制程序包

在官网选择编译后的压缩包下载
http://rocketmq.apache.org/release_notes/release-notes-4.2.0/
下图中红框处

或者去apache存档库中下载
http://archive.apache.org/dist/rocketmq/4.2.0/

下载好的文件: rocketmq-all-4.2.0-bin-release.zip

将下载好的zip包解压,注意路径也不要包含空格。

二、修改rocketmq配置
  这一步也可以跳过,但有可能会因为内存设置过大导致一系列的问题
需要执行的命令都在程序目录下的bin文件夹下,主要是mqnamesrv.cmd和mqbroker.cmd这两个命令,但他们又都各自调用了runserver.cmd和runbroker.cmd命令,分别修改这两个文件里的JAVA_OPT设置,如下
set "JAVA_OPT=%JAVA_OPT% -server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
将 Xms Xmx 这两个值改小一些,改为1g,如:
 
set "JAVA_OPT=%JAVA_OPT% -server -Xms1g -Xmx1g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

三、启动 NameServer

在rocketmq安装目录下的bin目录下,执行命令:

start mqnamesrv.cmd
mqnamesrv.cmd -n localhost:9876

出现The Name Server boot success.字样表示成功

四、启动 Broker

在rocketmq安装目录下的bin目录下,执行命令:

start mqbroker.cmd -n 127.0.0.1:9876 autoCreateTopicEnable=true
mqbroker.cmd -n localhost:9876

五、java示例代码
添加maven依赖
 
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>rocketmq-client</artifactId>
<version>4.2.0</version>
</dependency>

---------------------

消费者
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.message.MessageExt; import java.util.List; public class Consumer {
public static void main(String[] args) throws MQClientException {
DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("my-group"); consumer.setNamesrvAddr("localhost:9876");
consumer.setInstanceName("rmq-instance");
consumer.subscribe("demo-topic", "demo-tag"); consumer.registerMessageListener(new MessageListenerConcurrently() {
@Override
public ConsumeConcurrentlyStatus consumeMessage(
List<MessageExt> msgs, ConsumeConcurrentlyContext context) {
for (MessageExt msg : msgs) {
System.out.println(new String(msg.getBody()));
}
return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
}
});
consumer.start();
System.out.println("Consumer Started.");
}
}
---------------------

生产者

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 java.util.Scanner; public class Producer {
public static void main(String[] args) throws MQClientException {
DefaultMQProducer producer = new DefaultMQProducer("my-group");
producer.setNamesrvAddr("localhost:9876");
producer.setInstanceName("rmq-instance");
producer.start();
try {
Message message = new Message("demo-topic", "demo-tag", "这是一条测试消息".getBytes());
producer.send(message); while (true) {
String text = new Scanner(System.in).next();
Message msg = new Message("demo-topic",// topic
"demo-tag",// tag
text.getBytes() // body
);
SendResult sendResult = producer.send(msg);
}
} catch (Exception e) {
e.printStackTrace();
}
producer.shutdown();
}
}
---------------------
运行Consumer和Producer,然后在生产者控制台输入文本,在消费者控制台就可以看到消息了。
六、搭建RocketMQ  web控制台
1、访问 https://github.com/apache/rocketmq-externals/ ,
使用git将代码clone下来
2、修改项目配置信息
这是一个用springboot编写的工程,进入到 rocketmq-externals\rocketmq-console\src\main\resources 目录下,编辑 application.properties 文件, 修改mq的连接地址信息:
 
rocketmq.config.namesrvAddr=localhost:98761
3、启动项目
在rocketmq-externals\rocketmq-console目录下,执行:
nohup java -jar shareniu.jar >/dev/null  &  
 
mvn spring-boot:run
等待启动成功。
