django 和 celery+rabbitmq 的消费者连接错误?

2022-01-11 00:00:00 python django celery django-celery rabbitmq

问题描述

我正在尝试使用 django 和 rabbit-mq 设置 celeryd.到目前为止，我已经完成了以下工作:

I'm trying to set up celeryd with django and rabbit-mq. So far, I've done the following:

  • 从 pip 安装 celery
  • 通过存储库中可用的 deb 安装 rabbitmq
  • 通过 rabbitmqctl 向 rabbitmq 添加了一个用户和虚拟主机，以及该用户的权限
  • 启动rabbitmq-server
  • 通过 pip 安装 django-celery
  • 设置 django-celery，包括它的表
  • 在settings.py中配置好各种东西(BROKER_HOST, BROKER_PORT, BROKER_USER, BROKER_PASSWORD, BROKER_VHOST，以及导入djecelery，调用setup函数，添加到INSTALLED APPS).我仔细检查了所有这些值都是正确的(至少，用户、密码和虚拟主机是正确的).

所以现在，当我运行 python manage.py celeryd -l info 时出现连接错误(见下文).有人知道为什么吗?

So now, when I run python manage.py celeryd -l info I get connection errors (see below). Anyone have any idea why?

$ python manage.py celeryd -l info

解决方案

你的问题出在BROKER_URL.

使用额外的 VHOST，正确的配置应该是:

With an additional VHOST, the right config would be:

BROKER_URL='amqp://celeryuser@localhost:5672//'
BROKER_VHOST='/celeryhost'
