celery在Django中的使用

celery在Django中的使用

version
django==1.11.20
celery==3.1.26
django-celery==3.3.1
redis==2.10.6

window下
1.配置安装redis，手动命令启动redis，保证redis正常运行(嫌麻烦，配置成windows服务，搜索运行，输入services.msc，找到Redis启动即可)
2.在django项目settings同级的目录下创建celery.py文件
3.修改django项目settings同级的目录下__init__.py文件
4.安装django-celery(使用python manage.py 启动celery)
5.配置djcelery
INSTALLED_APPS = [
    ...
    'djcelery',
    ...
    ]
在settings里面写入celery一些配置即可
6.启动celery：python manage.py celery worker -l INFO
