问题描述
我有一个兔子 mq 在机器上运行
i have a rabbit mq running on machine
- 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
- 在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)
初始化 RPC 连接时随机超时
im getting random timeouts when initializing RPC connection
/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，不时发生.
problem is that the timeout isn't consistent and happens from time to time.
当手动测试这个问题并从同一台机器上运行 blocks_connection.py 1000 次时，它没有超时累积.
when manually testing this issue and running the blocking_connection.py 1000 times from the same machine that it fails no timeout accrue.
这是我失败时得到的错误:
this is the error i get when failing :

请帮忙
推荐答案
Pika 在连接不同主机时提供了一些超时问题.解决方案是在连接参数中传递一个 socket_timeout 参数.Pika 应该升级到>=0.9.14
Pika provides some time out issue when connecting different hosts.Solution is to pass a socket_timeout argument in connection parameter.Pika should upgrade to >=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()
