最近項(xiàng)目中用到celery很多，Django快速接入celery，這里給份教程。

準(zhǔn)備

pip安裝celery、flower、eventlet

快速接入

1.項(xiàng)目目錄的__init__文件

from __future__ import absolute_import# This will make sure the app is always imported when# Django starts so that shared_task will use this app.from .celerypro import app as celery_app

2.celerypro.py文件

from __future__ import absolute_importimport osfrom celery import Celeryfrom django.conf import settings# set the default Django settings module for the ’celery’ program.os.environ.setdefault(’DJANGO_SETTINGS_MODULE’, ’voice_quality_assurance_configure.settings’) #修改項(xiàng)目配置文件的地址app = Celery(’voice_quality_assurance_configure’) #修改項(xiàng)目目錄名稱# Using a string here means the worker will not have to# pickle the object when using Windows.app.config_from_object(’voice_quality_assurance_configure.celeryconfig’) #修改celery配置文件的地址app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

3.celeryconfig.py文件,更多配置項(xiàng)，可以查看官方文檔。

from kombu import QueueBROKER_URL = ’amqp://用戶名:密碼@ip:5672’# 指定 BrokerCELERY_RESULT_BACKEND = ’rpc://用戶名:密碼@ip:5672’# 指定 BackendCELERY_TIMEZONE=’Asia/Shanghai’# 指定時(shí)區(qū)，默認(rèn)是 UTCCELERY_TASK_SERIALIZER = ’pickle’CELERY_RESULT_SERIALIZER = ’pickle’CELERY_ACCEPT_CONTENT = [’pickle’, ’json’]CELERY_IGNORE_RESULT = True# CELERY_TIMEZONE=’UTC’CELERY_IMPORTS = ( # 指定導(dǎo)入的任務(wù)模塊 ’apps.mission.tasks’)CELERY_QUEUES = ( Queue(’default’, routing_key=’default’), #聲明隊(duì)列和對應(yīng)路由鍵 Queue(’worker_queue’, routing_key=’worker’), #聲明隊(duì)列和對應(yīng)路由鍵)CELERY_ROUTES = { ’apps.mission.tasks.createsingletask’: {’queue’: ’worker_queue’, ’routing_key’: ’worker’},}

app代碼如何使用

app下新建tasks.py文件，名字一定要是tasks。（我這里是mission app下的tasks.py）

from celery import shared_task@shared_task()def createsingletask(): print(test)

app下views調(diào)用如下：（我這里是mission app下的views.py）

from .tasks import createsingletask

createsingletask.apply_async(())

快速測試和監(jiān)控

啟動(dòng)多個(gè)celery worker，-A 指定項(xiàng)目目錄， -P 指定方式，我這里以協(xié)程方式運(yùn)行， -n指定name

celery worker -A voice_quality_assurance_configure --loglevel=info -P eventlet -n worker1celery worker -A voice_quality_assurance_configure --loglevel=info -P eventlet -n worker2celery worker -A voice_quality_assurance_configure --loglevel=info -P eventlet -n worker3celery worker -A voice_quality_assurance_configure --loglevel=info -P eventlet -n worker4celery worker -A voice_quality_assurance_configure --loglevel=info -P eventlet -n worker5

啟動(dòng)flower監(jiān)控

celery flower --broker=amqp://用戶名:密碼@ip:5672 --broker-api=http://用戶名:密碼@ip:15672/api/

查看監(jiān)控,注意這里的監(jiān)控?cái)?shù)據(jù)是不持久化的。

以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
