AMQP连接已被对等方重置，但已连接芹菜 [英] AMQP connection reset by peer, but celery connected
问题描述
我有一个烧瓶应用程序，使用Celery和RabbitMQ作为代理.
I have a flask app using Celery with RabbitMQ as the broker.
我已按照此>中的说明进行操作开始.
我有两台机器.
运行RabbitMQ的机器A发送要由机器B上的芹菜消耗的任务.
Machine A, where RabbitMQ runs, sends tasks to be consumed by celery on Machine B.
我的经纪人网址和后端结果网址相同:amqp://remote:***@12.345.678.999:5672/remote_host.
My Broker Url and Backend Result Url are the same: amqp://remote:***@12.345.678.999:5672/remote_host.
两台机器上都具有flask应用程序的副本.已配置RabbitMQ，以便用户远程用户具有.*.*.*"的所有权限.当它们都在计算机A的本地主机上运行时，RabbitMQ和Celery之间的所有通信都可以正常工作.
Both machines have copies of the flask app on them. RabbitMQ has been configured so that user remote has all permissions granted ".* .* .*". All the communication between RabbitMQ and Celery works fine when they're both running on localhost on Machine A.
我用celery worker -l info -A app.celery在机器B上开始芹菜，一切看起来都很好:
I start celery on Machine B with celery worker -l info -A app.celery, and everything looks fine:

当我在计算机A上运行该应用程序并尝试通过RabbitMQ将任务发送到Celery时，我得到了带有以下(部分)堆栈跟踪的[Errno 104] Connection reset by peer:
When I run the app on Machine A and try to send a task through RabbitMQ to Celery, I get [Errno 104] Connection reset by peer with the following (partial) stack trace:
File "/home/ubuntu/app/env/local/lib/python2.7/site-packages/amqp/abstract_channel.py", line 67, in wait
self.channel_id, allowed_methods, timeout)
File "/home/ubuntu/app/env/local/lib/python2.7/site-packages/amqp/connection.py", line 241, in _wait_method
channel, method_sig, args, content = read_timeout(timeout)
File "/home/ubuntu/app/env/local/lib/python2.7/site-packages/amqp/connection.py", line 330, in read_timeout
return self.method_reader.read_method()
File "/home/ubuntu/app/env/local/lib/python2.7/site-packages/amqp/method_framing.py", line 189, in read_method
raise m
error: [Errno 104] Connection reset by peer
我还获得了如下的AMQP调试状态网:
I also get an AMQP debug statemenet like the following:
amqp: DEBUG: Start from server, version: 0.9, properties: {u'information': u'Licensed under the MPL. See http://www.rabbitmq.com/', u'product': u'RabbitMQ', u'copyright': u'Copyright (C) 2007-2015 Pivotal Software, Inc.', u'capabilities':

我曾尝试查看Rabbitmqctl list_exchanges，list_consumers，list_bindings，但我对其中的内容并没有多大了解.
I've tried looking at rabbitmqctl list_exchanges, list_consumers, list_bindings, but I haven't been able to make much sense out of them.
如何调试它以弄清为什么RabbitMQ无法将任务发送到Celery?
How can I debug this to figure out why RabbitMQ can't send tasks to Celery?
推荐答案
I also have same requirements, I also followed this tutorial and It's working fine.
看起来像您的经纪人网址中的问题，只需尝试通过以下方式进行配置:
Looks like issue in your broker url, Just try to configure in following way :
from celery import Celery
app = Celery('tasks', backend='amqp',
broker='amqp://username:password@yourIp:5672//')
#Test Celery configuration
@app.task
def test(x, y):
return x + y
然后开始工作:
celery worker -l info -A app.celery
测试:
Python
>>> from app.celery import test
>>> test.delay(3,4)
<AsyncResult: 68480bd4-ebda-4238-87b1-ad896a75a12c>
并检查您的终端，您将获得预期的输出.
and check your terminal you will get expected output.
注意:我不知道它是否对您有用. 我这样做了，对我来说很好用.
Note: I don't know it will be work for you or not. I did this and it's working fine for me.
