我想打印"你好"每10秒钟。所以在我的终端中运行celery -A TwitterApiProxy beat
时,我看到如下:
LocalTime -> 2018-04-06 23:27:09
Configuration ->
. broker -> redis://localhost:6379//
. loader -> celery.loaders.app.AppLoader
. scheduler -> celery.beat.PersistentScheduler
. db -> celerybeat-schedule
. logfile -> [stderr]@%WARNING
. maxinterval -> 5.00 minutes (300s)
它没有打印任何与我安排的任务相关的内容。我哪里做错了?

您的设置没有问题。
让你的工人和芹菜在两个单独的cmd窗户中击败
celery -A TwitterApiProxy worker -l info
celery -A TwitterApiProxy beat -l info
如果您使用的是Celery 4.0+,则必须先安装eventlet,然后按照以下方式启动您的工作人员:
celery -A TwitterApiProxy worker -l info -P eventlet
任务管理员后端
如果您想要任务管理员后端,可以安装并使用django-celery
