Question

我在机器上运行了一个兔子mq

客户端和rabbitMQ都在同一个网络上运行
rabbitMQ有很多客户
我可以从rabbitMQ ping客户端并返回
在机器之间测量的最长延迟为12.1 ms
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连接时获取随机超时

/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。

手动测试此问题并在同一台机器上运行blocking_connection.py 1000次失败时，不会产生超时。

这是我失败时得到的错误：

我有类似的问题。如果一切看起来都很好，那么你很可能会有一些错过配置，例如：坏约束力。如果未配置，那么您将获得timeout，因为脚本无法到达其认为需要的位置，因此在这种情况下错误可能会失败。

对于我的问题，我特意遇到了我的rabbitmq.config文件和我的绑定问题，并且必须在我显示的命令行示例中使用我的python解决方案：RabbitMQ creating queues and bindings from a command line。一旦更新和配置正确，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提供了一些超时问题。解决方法是在连接参数中传递socket_timeout参数.Pika应该升级到＆gt; = 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()

Pika blocking_connection.py随机超时连接到RabbitMQ
