Python 烧瓶+；芹菜+；Redis:使用者：无法连接到amqp://guest:**@127.0.0.1:5672/：超时

我有一个简单的芹菜任务设置。为了运行它，我首先启动了redis服务器，然后激活虚拟环境并输入“芹菜节拍”，打开一个新的终端窗口进入虚拟环境并输入“芹菜工人”

这是随后的错误消息：

消费者：无法连接到amqp://guest:**@127.0.0.1:5672/：定时 出去

这是执行“芹菜节拍”后显示的配置详细信息：

配置-> . 经纪人->amqp://guest:**@本地主机：5672// . 加载器->芹菜.loaders.default.loader . 调度器->芹菜.beat.PersistentScheduler . db->celerybeat时间表 . 日志文件->[stderr]@%警告 . 最大间隔->5.00分钟（300秒）

如果我需要提供其他详细信息，请告诉我。

amqp是rabbitmq而不是redis

Redis通常是

redis://:password@hostname：端口/db\U编号

我会手动修改配置，看看它是否有效

flask_app.config.update(
    CELERY_BROKER_URL='redis://localhost:6379',
    CELERY_RESULT_BACKEND='redis://localhost:6379'
)

Django也有同样的问题，但我的问题是在settings.py中使用了“BROKER\u URL”而不是“芹菜\u BROKER\u URL”。Cellery找不到URL，默认为rabbitmq端口而不是redis端口。

在Django中也有同样的问题，但我的问题是在settings.py中使用了“BROKER\u URL”而不是“Cellery\u BROKER\u URL”。芹菜找不到URL，默认为rabbitmq端口，而不是redis端口。

您可以尝试将

Celery.conf.update（app.config）Celery.config\u行的顺序从\u对象（celeryconfig）

更改为

Celery.config\u从\u对象（celeryconfig）芹菜.conf.update（app.config）更改为
Celery.config\u行吗
在_init_u2; py中，您可以尝试将_init_2;object（celeryconfig）

中的

芹菜.conf.update（app.config）

行的顺序从_init_2;对象（celeryconfig）芹菜.conf.update（app.config）更改为芹菜.config\u，从_init_2;对象（celeryceryceryceryceryconfig）芹菜.conf！我认为，因为我没有指定应用程序名称，它以某种方式默认为rabbitmq。当我运行这个：“芹菜节拍-一个应用程序。芹菜”，它的工作。谢谢你的提示！我认为，因为我没有指定应用程序名称，它以某种方式默认为rabbitmq。当我运行这个：“芹菜节拍-一个应用程序。芹菜”，它的工作。谢谢是的，我不得不删除这一行。不仅如此，我没有指定应用程序名，它以某种方式默认为rabbitmq。当我运行这个：“芹菜节拍-一个应用程序。芹菜”，它的工作。谢谢是的，我不得不删除这一行。不仅如此，我没有指定应用程序名，它以某种方式默认为rabbitmq。当我运行这个：“芹菜节拍-一个应用程序。芹菜”，它的工作。
