python - Pika blocking_connection.py 随机超时连接到 RabbitMQ

Question

我有一个在机器上运行的 rabbit 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
• 机器之间测得的最长延迟为 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)

我在初始化 RPC 连接时随机超时

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

问题是超时时间不一致并且时有发生。

当手动测试此问题并从同一台机器运行 blocking_connection.py 1000 次时，它没有超时累积。

这是我失败时得到的错误:

请帮忙

我遇到了类似的问题。如果一切看起来都很好，那么您很可能有某种错误的配置，例如绑定(bind)不好。如果配置错误，那么您将得到一个超时，因为脚本无法到达它认为需要去的地方，所以在这种情况下错误可能是错误引导。

对于我的问题，我的 rabbitmq.config 文件和我的绑定(bind)都有问题，并且必须使用我显示的 python 解决方案:RabbitMQ creating queues and bindings from a command line 在我展示的命令行示例中。正确更新和配置后，一切正常。希望这能让您朝着正确的方向前进。
