Python3+Django3+Celery4+Rabbirmq 使用Celery，django配置信息
celery 支撑 django-celery-beat启动服务，需安装俩包：
pip install celery pip
install django-celery-beat
记得同步表
python manage.py makemigrations
Python manage migrate
django setting.py 文件配置信息：

启动服务：
celery -A human_drink_yq beat -l info --scheduler # 启动beat，注册任务
django_celery_beat.schedulers:DatabaseScheduler celery worker -A # 启动worker，执行任务
human_drink_yq -P gevent celery flower -A human_drink_yq # 启动flower，监听任务
python manage.py runserver # 启动django服务
