Docker 部署RabbitMQ

1.简介

该实例为了巩固docker知识
MQ全称Message Queue 消息队列，RabbitMQ是基于AMQP(高级消息队列协议)实现的。消息队列通常用以应用之间相互通信，解决同步问题,在项目中用到该消息队列,但是环境在服务器上(各种跳板),有时候自己测试不方便,故用docker搭建RabbitMQ本地环境,方便测试调试.
后续有关RabbitMQ的学习和深入就基于这个容器实操.

2.部署RabbitMQ

1、查询rabbitmq镜像

docker search rabbitmq:management

2、拉取rabbitmq镜像

docker pull rabbitmq:management

3.启动RabbitMQ

3.1.创建并启动容器

docker run -d --hostname my-rabbit --name rabbit -p 8080:15672 rabbitmq:management

ps:

--hostname：指定容器主机名称
--name:指定容器名称
-p:将mq端口号映射到本地

3.2备选启动同时设置用户和密码

docker run -d --hostname my-rabbit --name rabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management

ps: 此处的端口访问是有区别的，控制台端口用于管理rabbitmq，应用访问端口号为rabbitclient等应用访问。

15672：控制台端口号
 5672：应用访问端口号

3.3查看rabbitmq运行状况：

docker logs rabbit

3.4 访问

    http://localhost:15672

3.5 登陆
默认账号

Account  : guest
Password : guest

4.实操(Java)

启动Rabbit

docker run -d --hostname my-rabbit --name rabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management

ps:所用user>>> admin/admin

添加pom.xml依赖

    <dependencies>
        <!-- https://mvnrepository.com/artifact/com.rabbitmq/amqp-client -->
        <dependency>
            <groupId>com.rabbitmq</groupId>
            <artifactId>amqp-client</artifactId>
            <version>3.6.5</version>
        </dependency>
    </dependencies>

发送端(运行发送端,连续发送两条信息到指定队列)

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import java.util.concurrent.TimeoutException;

/**
 * @Auther: chenyj
 * @Date: 2018/12/4 10:58
 * @Description:
 */
public class Sender {
    //队列名称
    private final static String QUEUE_NAME = "hello";

    public static void main(String[] argv)throws java.io.IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();
        //Account
        factory.setUsername("admin");
        //Password
        factory.setPassword("admin");
        //rabbit所在服务器主机名
        factory.setHost("192.168.209.128");
        //应用访问端口
        factory.setPort(5672);
        //指定RabbitMQ服务器的虚拟主机
        factory.setVirtualHost("/");
        //创建连接
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        String message = "Hello World!";
        channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
        System.out.println(" [x] Sent '" + message + "'");
        channel.close();
        connection.close();
    }
}

UI查看
ps: 方才发送了两条信息

消费端

import com.rabbitmq.client.*;

import java.io.IOException;

/**
 * @Auther: chenyj
 * @Date: 2018/12/4 11:05
 * @Description:
 */
public class Receiver {
    //队列名称
    private final static String QUEUE_NAME = "hello";

    public static void main(String[] argv) throws Exception {
        ConnectionFactory factory = new ConnectionFactory();
        //Account
        factory.setUsername("admin");
        //Password
        factory.setPassword("admin");
        //rabbit所在服务器主机名
        factory.setHost("192.168.209.128");
        //应用访问端口
        factory.setPort(5672);
        //指定RabbitMQ服务器的虚拟主机
        factory.setVirtualHost("/");
        //连接参数
        factory.setConnectionTimeout(600000); // in milliseconds
        factory.setRequestedHeartbeat(60); // in seconds
        factory.setHandshakeTimeout(6000); // in milliseconds
        factory.setRequestedChannelMax(5);
        factory.setNetworkRecoveryInterval(500);

        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();

        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        System.out.println("Waiting for messages. ");

        Consumer consumer = new DefaultConsumer(channel) {
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
                    throws IOException {
                String message = new String(body, "UTF-8");
                System.out.println(" [x] Received '" + message + "'");
            }
        };
        channel.basicConsume(QUEUE_NAME, true, consumer);
    }

}

运行上述消费者,控制台输出

Waiting for messages. 
 [x] Received 'Hello World!'
 [x] Received 'Hello World!'

此时Rabbit页面已经全部消费成功
