## 使用guest用户远程连接RabbitMQ用户名密码错误 ##

使用的是默认用户guest，密码也是guest

代码：

package com.adtec.rabbitmq;
    
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.ConnectionFactory;
    
    public class Send {
    
      private final static String QUEUE_NAME = "hello";
    
      public static void main(String[] argv) throws Exception {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("192.168.71.111");
        factory.setUsername("guest");
        factory.setPassword("guest");
        factory.setPort(5672);
        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("UTF-8"));
        System.out.println(" [x] Sent '" + message + "'");
    
        channel.close();
        connection.close();
      }
    }

错误信息：

[AMQP Connection 192.168.71.111:5672] WARN com.rabbitmq.client.impl.ForgivingExceptionHandler - An unexpected connection driver error occured (Exception message: Connection reset)

**我在Windows机器上也装了一个RabbitMQ，也用这个用户登录，结果是可以！！！**

package com.adtec.rabbitmq;
    
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.ConnectionFactory;
    
    public class Send {
    
      private final static String QUEUE_NAME = "hello";
    
      public static void main(String[] argv) throws Exception {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        factory.setUsername("guest");
        factory.setPassword("guest");
        factory.setPort(5672);
        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("UTF-8"));
        System.out.println(" [x] Sent '" + message + "'");
    
        channel.close();
        connection.close();
      }
    }

查了官网才知道  
  
因为guest用户只是被容许从localhost访问。官网文档描述如下：  
  
**"guest" user can only connect via localhost**

有兴趣的可以详细了解：[http://www.rabbitmq.com/access-control.html][http_www.rabbitmq.com_access-control.html]  
  
解决办法就是新建用户并授权  
  
新建test用户，授予administrator权限

rabbitmqctl add_user test root
    rabbitmqctl set_user_tags test administrator
    rabbitmqctl set_permissions -p / test ".*" ".*" ".*"
