    一、None of the specified endpoints were reachable
    这个异常在创建连接时抛出(CreateConnection()),原因一般是ConnectionFactory参数设置不对,比如HostName、UserName、Password
    标准设置:
    var factory = new ConnectionFactory();
    factory.UserName = QueueSetttiong.UserName;   //用户名
    factory.Password = QueueSetttiong.Password;      //密码
    factory.HostName = QueueSetttiong.HostName;  //Rabbitmq服务IP,不包含端口
    factory.Port = AmqpTcpEndpoint.UseDefaultPort;
    factory.VirtualHost = QueueSetttiong.VirtualHost;  //默认为"/"
    factory.Protocol = Protocols.DefaultProtocol;
     
    部署生产后,factory配置都ok,但是还是抛异常None of the specified endpoints were reachable,最后发现原因是生产机器防火墙未打开RabbitMQ的端口,RabbitMQ的默认端口是:5672



    另外一个可能的原因:未设置VirtualHost的权限

    设置方法:RabbitmqWeb管理网站-->Admin

    未设置权限时:

    设置权限:(点击admin进入设置页面)

     

     二、异常:unable to connect to node rabbit@10: nodedown

    网上说要修改主机名,找半天不知道怎么修改,重新安装Rabbitmq服务端即可,有时候需要重启

     三、异常:Message:Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=320, text="CONNECTION_FORCED - broker forced connection closure with reason 'shutdown'", classId=0, methodId=0, cause= StackTrace

    原因:队列服务端重启后,队列发布端断开了接口,无法再次发送消息

    解决:发送端设置断开连接后自动启动属性,默认为断开后每隔五秒钟重试连接

     var factory = new ConnectionFactory();

    factory.AutomaticRecoveryEnabled = true;   //设置端口后自动恢复连接属性即可

    四、Rabbitmq实际数据文件、日志文件、配置文件路径

    地址栏输入:%APPDATA%RabbitMQ

    C:UsersAdministratorAppDataRoamingRabbitMQ

    信息来源:C:Program Files (x86)RabbitMQ Server abbitmq_server-3.5.1etc 中的README.txt
