celery: 定时任务

一，mytask.py代码：

from celery import Celery
from datetime import timedelta

celeryApp = Celery('celeryapp', broker='redis://localhost:6379/0', backend='redis://localhost:6379/1')

celeryApp.conf.beat_schedule = {
    'add-every-30-seconds': {
        'task': 'mytask.my_task1',
        'schedule': timedelta(seconds=30), # 每30秒执行一次
        'args': (16, 16),
    },
}

# 设置周期性任务
@celeryApp.task
def my_task1(a, b):
    print("my_task1任务正在执行....")
    return a + b

if __name__=="__main__":
    celeryApp.start()

 

二，测试 效果 ：

运行:

$ celery -A mytask worker --loglevel=info --beat

效果:
