Question

我尝试使用tutorial

中提到的链接任务运行一个非常简单的任务

add.apply_async((2, 2), link=add.s(16))

并在工作进程中遇到异常：

[2014-09-21 19:56:38,531: WARNING/Worker-1] C:\Python33\lib\site-packages\celery-3.1.15-

During handling of the above exception, another exception occurred:

    raise socket.error(last_err)
OSError: [WinError 10061] No connection could be made because the target machine actively refused it

我在transport.py中做了一个简短的调试，发现该worker正在尝试连接到localhost上的端口5672。似乎工作者认为链接的任务需要通过本地RabbitMQ实例执行。这很奇怪，因为我在配置设置中指定了一个远程RabbitMQ代理。如果我只是在没有链接任务的情况下运行异步调用，该设置也可以工作：

add.apply_async((2, 2))

这是我的设置：

将RabbitMQ用作代理，将Redis用作远程Windows服务器上的结果
在另一台Windows 7计算机上运行我的测试客户端

任何人都能解开一些光明吗？谢谢。
