手把手教学--从Pulsar到TDMQ

导语：介于TDMQ还没有公网的访问功能，不可能买台CVM安装windows吧，VPN又只能支持协议类型：IKE/IPsec，意思是企业用户才能用，对于个人就只能再想办法了，但办法总比问题多。本地开发测试环境使用pulsar的单机版，生产使用TDMQ，这样怎么样，一起来看看怎么配置。

一、用CVM安装单机版的pulsar

1、安装JDK1.8

下载JDK1.8：https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

a、将免安装的JDK拷贝到linux目录下

/etc/jdk1.8.0_271

b、更改环境变量

vim /etc/profile

代码语言：javascript复制

export JAVA_HOME=/etc/jdk1.8.0_271
export PATH=.:$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

c、刷新配置

source /etc/profile

这样就可以了

2、安装pulsar

下载安装二进制版本pulsar：http://pulsar.apache.org/docs/zh-CN/next/standalone/

这里下载比较快：

解压之后启动：bin/pulsar-daemon start standalone

启动日志（简略版）：

代码语言：javascript复制

14:09:02.467 [main] INFO  org.apache.pulsar.zookeeper.LocalBookkeeperEnsemble - Server UP

14:09:03.143 [main] INFO  org.apache.bookkeeper.bookie.storage.ldb.DbLedgerStorage - Creating single directory db ledger storage on data/standalone/b
ookkeeper0/current

注：如果使用命令在后台运行服务:pulsar-daemon start standalone；则可以通过以下命令终止服务：pulsar-daemon stop standalone

3、使用pulsar-client测试生产消费

Produce 消息：

向名称为 my-topic 的 topic 发送一条简单的消息 hello-pulsar：

bin/pulsar-client produce my-topic --messages "hello-pulsar"

Consume 消息：

在 first-subscription 订阅的my-topic消费消息：

bin/pulsar-client consume my-topic -s "first-subscription"

这样是消费到消息了，单机版的pulsar是可以使用的。

二、搭建本地开发环境

1、下载TDMQ的demo：

https://github.com/TencentCloud/tdmq-java-client

2、下载Pulsar的Java SDK 下载方式：

您 Java 工程的 全整pom.xml

代码语言：javascript复制

在 pom.xml 所在目录执行即可下载 Pulsar SDK。

代码语言：javascript复制

mvn clean package

3、连接单机版的pulsar的测试代码：SimpleProducerAndCosnumer.java

代码语言：javascript复制

package com.tencent.tdmq.demo.cloud;

import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.core.joran.spi.JoranException;
import org.apache.pulsar.client.api.*;
import org.slf4j.LoggerFactory;

import java.util.HashMap;
import java.util.Map;

//import org.apache.pulsar.client.api.NetModel;

/**
 * 简单的生产和消息例子
 *
 */

public class SimpleProducerAndCosnumer {

	public static void invork() throws PulsarClientException {
		Map<String, String> authParams = new HashMap<>();
		//authParams.put("secretId", "AKID6VfaFeTq12nJadkMnOhMFveVR7XjfMnQ");
		//authParams.put("secretKey", "aS2MbkLafbiXO2RM1nTv51h8uW9XQb1t");
		//authParams.put("region", "ap-guangzhou");
		PulsarClient client = PulsarClient.builder()
				//.serviceUrl("pulsar://10.0.0.4:6000")// 填写腾讯云TDMQ接入点的地址
		        //.listenerName("custom:pulsar-geookmr4pz/vpc-paywuhyf/subnet-6jummj9y")
				//.authentication(AuthenticationFactory.token("eyJrZXlJZCI6In9va21yNHB6IiB1bHNhci1nZWwiYWxnIjoiSFMyNTYifQ.eyJzdWIiOiJkZGRkIn0.otXNHuw3FJhQ0l4msNQe_zAH2Bh7lB8kVrfoU4XRTqs"))
				.serviceUrl("pulsar://110.29.14.63:6650")// 填写测试环境pulsar的地址
				.build();
		// 创建消费者对象
		Consumer<byte[]> consumer = client.newConsumer()
				//.topic("persistent://pulsar-geookmr4pz/default/sfhuang")//命名规则:appid/namespace/topic
				.topic("my-topic")
				.subscriptionName("sub-sfhuang")
				.subscribe();
		// 创建生产者对象
		Producer<byte[]> producer = client.newProducer()
				//.topic("persistent://pulsar-geookmr4pz/default/sfhuang")//这个是腾讯云的topic
				.topic("my-topic")
				.create();

		for (int i = 0; i < 5; i  ) {
			String value = "my-sync-message-"   i;
			System.out.println("");
			MessageId msgId = producer.newMessage().value(value.getBytes()).send();
			System.out.println("produce sync msg id:"   msgId   ", value:"   value);
		}
		producer.close();
		for (int i = 0; i < 5; i  ) {
			Message<byte[]> msg = consumer.receive();
			String msgId = msg.getMessageId().toString();
			String value = new String(msg.getValue());
			System.out.println("receive msg "   msgId   ",value:"   value);
			consumer.acknowledge(msg);
		}
		// 关闭
		consumer.close();
		client.close();
	}

	public static void main(String[] args) throws JoranException, PulsarClientException {
		String logbackFile = "D:\programming\tdmq-java-client-master\conf\logback.xml";
		//String logbackFile = "/root/tdmq-demo-cloud-0.0.1-SNAPSHOT/conf/logback.xml";
		if (logbackFile != null) {
			LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
			JoranConfigurator configurator = new JoranConfigurator();
			configurator.setContext(lc);
			lc.reset();
			configurator.doConfigure(logbackFile);
		}
		invork();

	}

}

还有logback.xml文件也要修改：

本地运行结果是：

也是可以生产和消费搭建在CVM上的Pulsar

三、测试连接TDMQ并生产消费

1、创建TDMQ的topic

默认创建在default环境

2、创建接入点

这里要选CVM所在的VPC子网，才通连通，地址和路由ID都会在代码中用到。

3、创建角色

秘钥是在这里，代码中也会用到

4、对环境进行权限配置

有读写的权限：

5、创建订阅者

这里的订阅者需要在控制台创建，系统会生产两个topic，一个是重试队列，一个是死信队列

订阅者：sub-sfhuang

6、修改本地代码：

代码语言：javascript复制

package com.tencent.tdmq.demo.cloud;

import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.core.joran.spi.JoranException;
import org.apache.pulsar.client.api.*;
import org.slf4j.LoggerFactory;

import java.util.HashMap;
import java.util.Map;

//import org.apache.pulsar.client.api.NetModel;

/**
 * 简单的生产和消息例子
 *
 */

public class SimpleProducerAndCosnumer {

	public static void invork() throws PulsarClientException {
		Map<String, String> authParams = new HashMap<>();
		authParams.put("secretId", "AKID6VfaFeTq12nJadkMnOhMFveVR7XjfMnQ");
		authParams.put("secretKey", "aS2MbkLafbiXO2RM1nTv51h8uW9XQb1t");
		authParams.put("region", "ap-guangzhou");
		PulsarClient client = PulsarClient.builder()
				.serviceUrl("pulsar://10.0.0.4:6000")// 填写腾讯云TDMQ接入点的地址
		        .listenerName("custom:pulsar-geookmr4pz/vpc-paywuhyf/subnet-6jummj9y")//路由ID
				.authentication(AuthenticationFactory.token("eyJrZXlJZCI6In9va21yNHB6IiB1bHNhci1nZWwiYWxnIjoiSFMyNTYifQ.eyJzdWIiOiJkZGRkIn0.otXNHuw3FJhQ0l4msNQe_zAH2Bh7lB8kVrfoU4XRTqs"))//秘钥
				//.serviceUrl("pulsar://110.29.14.63:6650")// 填写测试环境pulsar的地址
				.build();
		// 创建消费者对象
		Consumer<byte[]> consumer = client.newConsumer()
				.topic("persistent://pulsar-geookmr4pz/default/sfhuang")//这个是腾讯云TDMQ的topic
				//.topic("my-topic")
				.subscriptionName("sub-sfhuang")//这个要在控制台创建
				.subscribe();
		// 创建生产者对象
		Producer<byte[]> producer = client.newProducer()
				.topic("persistent://pulsar-geookmr4pz/default/sfhuang")//这个是腾讯云的topic
				//.topic("my-topic")
				.create();

		for (int i = 0; i < 5; i  ) {
			String value = "my-sync-message-"   i;
			System.out.println("");
			MessageId msgId = producer.newMessage().value(value.getBytes()).send();
			System.out.println("produce sync msg id:"   msgId   ", value:"   value);
		}
		producer.close();
		for (int i = 0; i < 5; i  ) {
			Message<byte[]> msg = consumer.receive();
			String msgId = msg.getMessageId().toString();
			String value = new String(msg.getValue());
			System.out.println("receive msg "   msgId   ",value:"   value);
			consumer.acknowledge(msg);
		}
		// 关闭
		consumer.close();
		client.close();
	}

	public static void main(String[] args) throws JoranException, PulsarClientException {
		//String logbackFile = "D:\programming\tdmq-java-client-master\conf\logback.xml";
		String logbackFile = "/root/tdmq-demo-cloud-0.0.1-SNAPSHOT/conf/logback.xml";
		if (logbackFile != null) {
			LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
			JoranConfigurator configurator = new JoranConfigurator();
			configurator.setContext(lc);
			lc.reset();
			configurator.doConfigure(logbackFile);
		}
		invork();

	}

}

还有logback.xml文件也要修改：

7、在 pom.xml 所在目录执行即可打zip包。

代码语言：javascript复制

mvn clean package

zip包在我本地所在的目录：

四、打包上传并测试

这里的生产环境也是要有JDK1.8，可以使用Pulsar单机版的机器测试

1、上传zip包

[root@VM-0-9-centos ~]# rz

Sent - tdmq-demo-cloud-0.0.1-SNAPSHOT-bin.zip 5.25 MB/s Spend: 5 seconds

2、解压

drwxr-xr-x 2 root root 4096 Nov 19 11:34 bin

drwxr-xr-x 2 root root 4096 Dec 3 11:16 conf

drwxrwxrwx 2 root root 4096 Dec 3 12:49 lib

3、授予执行权限

[root@VM-0-9-centos tdmq-demo-cloud-0.0.1-SNAPSHOT]# chmod 755 bin/runserver.sh

4、运行代码

[root@VM-0-9-centos tdmq-demo-cloud-0.0.1-SNAPSHOT]# bin/runserver.sh -classpath lib/tdmq-demo-cloud-0.0.1-SNAPSHOT.jar com.tencent.tdmq.demo.cloud.SimpleProducerAndCosnumer

结果：成功了！！！

总结：使用线上的TDMQ省去了运维，扩展性也会更好，配置也不复杂，公测期间还免费，快快来体验一下吧。

后面会为大家分享TDMQ的其它使用。
