安装依赖
pip install django-celery-beat pip install django-celery-email pip install celery pip install msgpack-python pip install msgpack
在settings文件中配置
添加app应用到installed_apps中
"djcelery_email", "django_celery_beat"
修改.env文件配置：
#邮箱后端，使用celery email DJANGO_EMAIL_BACKEND=djcelery_email.backends.CeleryEmailBackend DJANGO_EMAIL_HOST=smtp.qq.com DJANGO_EMAIL_HOST_USER=xxx@qq.com # 您的邮箱号 DJANGO_EMAIL_HOST_PASSWORD=你的邮箱密码 DJANGO_DEFAULT_FROM_EMAIL=默认发送的邮箱号 #CELERY CELERY_BROKER_URL=redis://127.0.0.1:6379/1 #使用redis 1作为消息代理 CELERY_RESULT_BACKEND=redis://127.0.0.1:6379/2 #把任务结果放在redis2库中
添加配置项：
# Celery
# ------------------------------------------------------------------------------
if USE_TZ:
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-timezone
CELERY_TIMEZONE = TIME_ZONE
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-broker_url
CELERY_BROKER_URL = env("CELERY_BROKER_URL")
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-result_backend
CELERY_RESULT_BACKEND = env('CELERY_RESULT_BACKEND')
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-accept_content
CELERY_ACCEPT_CONTENT = ["json", 'msgpack']
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-task_serializer
CELERY_TASK_SERIALIZER = "msgpack"
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-result_serializer
CELERY_RESULT_SERIALIZER = "json"
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#task-time-limit
# TODO: set to whatever value is adequate in your circumstances
CELERY_TASK_TIME_LIMIT = 5 * 60
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#task-soft-time-limit
# TODO: set to whatever value is adequate in your circumstances
CELERY_TASK_SOFT_TIME_LIMIT = 60
# http://docs.celeryproject.org/en/latest/userguide/configuration.html#beat-scheduler
CELERY_BEAT_SCHEDULER = "django_celery_beat.schedulers:DatabaseScheduler"
EMAIL_BACKEND = env(
"DJANGO_EMAIL_BACKEND", default="djcelery_email.backends.CeleryEmailBackend"
)添加邮箱配置项：
EMAIL_HOST = env('DJANGO_EMAIL_HOST', default="smtp.qq.com")
EMAIL_USE_SSL = env('DJANGO_EMAIL_USE_SSL', default=True)
EMAIL_PORT = env('DJANGO_EMAIL_PORT', default=465)
EMAIL_HOST_USER = env('DJANGO_EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = env('DJANGO_EMAIL_HOST_PASSWORD')
DEFAULT_FROM_EMAIL = env('DJANGO_DEFAULT_FROM_EMAIL')编写celery文件
在项目配置的目录下新增celery_app.py文件
import os
from celery import Celery
# set the default Django settings module for the 'celery' program.
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")
app = Celery("你的项目名")
# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
# should have a `CELERY_` prefix.
app.config_from_object("django.conf:settings", namespace="CELERY")
# Load task modules from all registered Django app configs.
app.autodiscover_tasks()在某app目录下新增tasks.py文件：
from django.conf import settings from django.core.mail import send_mail from config import celery_app # 打上装饰器celery就会自动搜索到添加到任务中 @celery_app.task() def send_activity_verify_email(): """异步发送新订单邮件""" title = '[学时通] 您有一个新活动等待审核' message = '您有一个新活动等待审核，请进入学时通管理系统查看' send_mail(title, message=message, from_email=settings.DEFAULT_FROM_EMAIL, recipient_list=settings.EMAIL_RECIPIENT_LIST)
启动celery
来到项目目录下：
执行以下命令
其中config为我的项目配置目录，config.celery_app指我项目配置目录下的celery_app文件
$ /usr/local/python3/bin/celery -A config.celery_app worker -l info
当点击发送邮件时，celery会把任务添加到redis 1库中，邮箱发送完毕后，会在redis 2库中显示结果。
