Question

使用rabbitmq作为芹菜的经纪人。运行命令时出现问题

celery -A proj worker   --loglevel=info

芹菜控制台显示此

[2017-06-23 07:57:09,261: ERROR/MainProcess] consumer: Cannot connect to amqp://bruce:**@127.0.0.1:5672//: timed out.
Trying again in 2.00 seconds...

[2017-06-23 07:57:15,285: ERROR/MainProcess] consumer: Cannot connect to amqp://bruce:**@127.0.0.1:5672//: timed out.
Trying again in 4.00 seconds...

以下是来自rabbitmq的日志

=ERROR REPORT==== 23-Jun-2017::13:28:58 ===

任何意见都会受到赞赏。

Answer 1

我知道它已晚了

但是今天我遇到了同样的问题，花了差不多一个小时才找到确切的解决办法。认为它可能会帮助别人

我使用的是芹菜版4.1.0

希望您已正确配置RabbitMQ，如果没有，请按照页面http://docs.celeryproject.org/en/latest/getting-started/brokers/rabbitmq.html#setting-up-rabbitmq

中的说明对其进行配置

还要交叉检查经纪人网址是否正确。这是brocker url语法 AMQP：// <强> USER_NAME ：密码 @的本地主机 / <强>主机名

您可能不需要指定端口号，因为它会自动选择默认值

如果您按照上面的安装教程链接中的相同变量进行操作，那么您的Brocker网址就会如此的 AMQP：//为myuser：输入mypassword @本地/ myvhost

遵循此项目结构

Project ../app ../Project ../settings.py ../celery.py ../tasks.py ../celery_config.py

<强> celery_config.py

# - - - - - - - - - - # BROKER SETTINGS # - - - - - - - - - - # BROKER_URL = os.environ['APP_BROKER_URL'] BROKER_HEARTBEAT = 10 BROKER_HEARTBEAT_CHECKRATE = 2.0 # Setting BROKER_POOL_LIMIT to None disables pooling # Disabling pooling causes open/close connections for every task. # However, the rabbitMQ cluster being behind an Elastic Load Balancer, # the pooling is not working correctly, # and the connection is lost at some point. # There seems no other way around it for the time being. BROKER_POOL_LIMIT = None BROKER_TRANSPORT_OPTIONS = {'confirm_publish': True} BROKER_CONNECTION_TIMEOUT = 20 BROKER_CONNECTION_RETRY = True BROKER_CONNECTION_MAX_RETRIES = 100

<强> celery.py

from __future__ import absolute_import, unicode_literals from celery import Celery from Project import celery_config app = Celery('Project', broker='amqp://myuser:mypassword@localhost/myvhost', backend='amqp://', include=['Project']) # Optional configuration, see the application user guide. # app.conf.update( # result_expires=3600, # CELERY_BROKER_POOL_LIMIT = None, # ) app.config_from_object(celery_config) if __name__ == '__main__': app.start()

<强> tasks.py

from __future__ import absolute_import, unicode_literals from .celery import app @app.task def add(x, y): return x + y

然后从项目目录“celery -A Project worker -l info”启动芹菜

一切都会好的。

Answer 2

在settings.py中设置CELERY_BROKER_POOL_LIMIT =无
