我有一个在机器上运行的兔子 mq

  • 客户端和rabbitMQ都在同一个网络上运行
  • rabbitMQ有很多客户端
  • 我可以从 rabbitMQ ping 客户端并返回
  • 机器之间测量的最长延迟为 12.1 毫秒
  • 网络详细信息：标准交换机网络（在单个物理机上运行的虚拟机网络 - 使用 vmware VC）

初始化 RPC 连接时出现随机超时

/usr/lib/python2.6/site-packages/pika-0.9.5-py2.6.egg/pika/adapters/blocking_connection.py

问题是超时不一致并且不时发生。

当手动测试此问题并从同一台机器上运行blocking_connection.py 1000 次时，它不会产生超时。

这是我失败时得到的错误：

我有一个类似的问题。如果一切看起来都很好，那么您很可能有某种未配置的配置，例如绑定错误。如果未配置，那么您将得到一个timeout，因为脚本无法到达它认为它需要去的地方，所以在这种情况下错误可能会导致错误。

对于我的问题，我的rabbitmq.config文件和绑定都特别有问题，因此不得不使用我的 python 解决方案，如下所示： RabbitMQ通过我展示的命令行示例从命令行创建队列和绑定。正确更新和配置后，一切正常。希望这能让你朝着正确的方向前进。

Pika 在连接不同的主机时会出现一些超时问题。解决方案是socket_timeout在连接参数中传递一个参数。Pika 应该升级到 >=0.9.14

credentials = pika.PlainCredentials(RABBITMQ_USER, RABBITMQ_PASS)
connection = pika.BlockingConnection(pika.ConnectionParameters(
    credentials=credentials,
        host=RABBITMQ_HOST,
         socket_timeout=300))
channel = connection.channel()
