python + celery简例

在网上找了半天，也没找到完整的例子，自己写吧

1. 一个队列,自定义10个优先级，修改默认celery队列名称

1) testcelery.py

from celery import Celery
import time

broker  = 'redis://:passwd@127.0.0.1:6279/0'
backend = 'redis://:passwd@127.0.0.1:6279/1'
app = Celery('test',backend=backend,broker=broker)

app.conf.broker_transport_options = {
    'priority_steps': list(range(10)),
    'sep': ':',
    'queue_order_strategy': 'priority',
}

app.conf.task_default_queue = 'autotest'

@app.task(priority=0)
def add(x, y):
    time.sleep(2)
    return x + y

@app.task(priority=5)
def minus(x, y):
    time.sleep(1)
    return x - y

@app.task(priority=8)
def multiply(x, y):
    time.sleep(1)
    return x * y
