用Docker 构建RabbitMQ shovel(静态)-优快云博客

本文介绍了如何通过Docker启动两个RabbitMQ节点，并利用RabbitMQ的Shovel插件实现远程通信和数据复制。详细步骤包括启动Docker容器、启用Shovel插件、获取节点IP、编辑rabbitmq.config文件、替换配置、重启容器以及在源和目标节点上分别创建生产者和消费者。

实现RabbitMQ的远程通信和复制，可以在广域网上使用

1.用Docker启动两个RabbitMQ节点

docker run -d --name=rabbitmqa -p 5772:5672 -p 15772:15672 -e RABBITMQ_NODENAME=rabbitmqa -h rabbitmqa rabbitmq:3.6.9-management

docker run -d --name=rabbitmqb -p 5773:5672 -p 15773:15672 -e RABBITMQ_NODENAME=rabbitmqb -h rabbitmqb rabbitmq:3.6.9-management

2.开启shovel插件

docker exec rabbitmqa bash -c "rabbitmq-plugins enable rabbitmq_shovel"

docker exec rabbitmqa bash -c "rabbitmq-plugins enable rabbitmq_shovel_management"

docker exec rabbitmqb bash -c "rabbitmq-plugins enable rabbitmq_shovel"

docker exec rabbitmqb bash -c "rabbitmq-plugins enable rabbitmq_shovel_management"

3.获得两个RabbitMQ节点的IP

docker inspect --format='{{ .NetworkSettings.IPAddress }}' rabbitmqa

docker inspect --format='{{ .NetworkSettings.IPAddress }}' rabbitmqb

4.编辑rabbitmq.config文件，在附件中

5.替换Docker容器中的rabbitmq.config文件

只需替换source节点的配置文件

docker cp /home/robbie/Downloads/rabbitmq.config 017bf80d9b22:/etc/rabbitmq/rabbitmq.config

6.重启docker容器

docker restart rabbitmqa

docker restart rabbitmqb

在RabbitMQ的管理页面上可以看见两个节点上已经自动创建了对应的queue和exchange

7.在destinations RabbitMQ节点(rabbitmqb)上创建消费者

public class Consumer {
    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("localhost");
        connectionFactory.setPort(5773);
        connectionFactory.setUsername("guest");
        connectionFactory.setPassword("guest");
        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        channel.basicConsume("warehouse_carpinteria",true,"order_processor",new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println("Message is: " + new String(body));
//                channel.basicAck(envelope.getDeliveryTag(),false);
            }
        });
    }
}

8.在source RabbitMQ节点(rabbitmqa)上创建生产者

@Test
	public void producer() throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("localhost");
        connectionFactory.setPort(5772);
        connectionFactory.setUsername("guest");
        connectionFactory.setPassword("guest");
        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        channel.exchangeDeclare("incoming_orders","direct",true);
        channel.basicPublish("incoming_orders", "warehouse", null, "RabbitMQ shovel test...".getBytes());
        channel.close();
        connection.close();
    }

先运行消费者，然后再执行生产者，可以参考RabbitMQ in action这本书。
