celery异布任务第一弹

celery_demo.py

import time

from celery import Celery

broker = 'redis://:123456@localhost/1'#存储任务

backend = 'redis://:123456@localhost/2'#存储任务执行结果

app = Celery('demo', broker=broker, backend=backend)


@app.task
def add(x, y):
    z = x + y
    print(f'求和{x}+{y}={z}')
    time.sleep(1)
    return z

右键运行脚本，提交此任务，但不会执行

终端命令：
1.启动worker，worker会执行被提交的任务，把执行结果存入redis的2号库
