如何配置和运行celerybeat

问题描述

我刚开始做芹菜，试图执行一项定期任务.

I am just getting started with celery,trying to run a periodic task.

已配置* rabbitmq **添加了celeryconfig.py.

Configured *rabbitmq** added celeryconfig.py.

并在task.py中添加了以下代码:

And added following code in tasks.py:

from celery.decorators import periodic_task
from datetime import timedelta

@periodic_task(run_every=timedelta(seconds=2))
def every_2_seconds():
    print("Running periodic task!")

现在，当我通过在终端中输入"celerybeat"来启动celerybeat时，它将开始运行并跟随以下消息

Now when I start celerybeat by typing "celerybeat" in my terminal it starts to run with follwing message

celerybeat
celerybeat v3.0.3 (Chiastic Slide) is starting.
__    -    ... __   -        _
Configuration ->
    . broker -> amqp://arnold@localhost:5672//
    . loader -> celery.loaders.default.Loader
    . scheduler -> celery.beat.PersistentScheduler
    . db -> celerybeat-schedule
    . logfile -> [stderr]@INFO
    . maxinterval -> now (0s)
[2012-08-03 14:24:52,202: INFO/MainProcess] Celerybeat: Starting...

并且终端中没有 every_2_seconds 方法的输出.我假设我必须在celerybeat命令期间指定要运行或执行任务的应用程序.

And there is no output of every_2_seconds method in the terminal.I am assuming I have to specify which app to run or wich tasks during the celerybeat command.How to do that?

我如何指定任务并每隔2秒打印一行作为定期任务?

How can I specify tasks and print the line after every 2 seconds as a periodic tasks?

谢谢.

推荐答案

在您的celeryconfig.py中添加 CELERY_IMPORTS =("tasks"，)，然后运行celerybeat.

Add CELERY_IMPORTS=("tasks",) to your celeryconfig.py then run celerybeat.
