我正在尝试用django和rabbit-mq建立芹菜。到目前为止,我已经完成了以下工作:
现在,当我运行python manage.py celeryd -l info
时,我收到连接错误(见下文)。任何人都知道为什么?
$ python manage.py celeryd -l info

您的问题出在BROKER_URL
。
使用额外的VHOST
,正确的配置将是:
BROKER_URL='amqp://celeryuser@localhost:5672//'
BROKER_VHOST='/celeryhost'
答案 1 :(得分:4)
对我来说,以下网址结尾有效: ... @本地:5672 / celeryvhost
答案 2 :(得分:4)
我与RabbitMQ有类似的问题,问题是我的用户没有在RabbitMQ中创建消息的权限。
尝试使用 guest 用户在RabbitMQ服务器上运行以下脚本,如果它创建了一个作业,请与您的用户一起尝试:
from celery import Celery
app = Celery('tasks', broker='amqp://radek:**@localhost:5672//')
@app.task
def add(x, y):
return x + y
如果您遇到同样的错误,只需为您的用户设置权限:
rabbitmqctl set_permissions -p / radek ".*" ".*" ".*"

您的rabbitmq服务器不能正常启动和/或配置。确认它是,然后再试一次 - 或者,更好的是,如果你只是想测试一些东西并且你是队列不可知的,取出rabbitmq并开始使用redis。配置起来要容易得多。
我只是从我的一个项目中剪切并粘贴了这段代码,它运行得很好:
import djcelery
from datetime import timedelta
djcelery.setup_loader()
BROKER_BACKEND = "redis"
BROKER_HOST = "localhost"
BROKER_PORT = 6379
BROKER_VHOST = "0"
CELERYD_LOG_LEVEL = 'DEBUG'
CELERY_RESULT_BACKEND = "redis"
CELERY_TASK_RESULT_EXPIRES = 150000
REDIS_HOST = "localhost"
REDIS_PORT = 6379
REDIS_DB = "0"
CELERYD_CONCURRENCY = 1
CELERYD_MAX_TASKS_PER_CHILD = 4
CELERY_IMPORTS = (
"apps.app1.tasks",
"apps.app2.tasks",
)

您的BROKER_URL在settings.py中的含义是什么?
默认情况下,RabbitMQ有一个访客用户,所以如果你可以连接
BROKER_URL = "amqp://guest:guest@localhost:5672//"
然后问题是您为RabbitMQs用户,密码或虚拟主机设置。
