解决办法，启动的时候，使用eventlet 方式，
pip install eventlet
celery -A celery_tasks worker -l info -P eventlet -c 10
##-c是协程的数量，生产环境可以用1000
原因：celery不支持在windows下运行任务，需要借助eventlet来完成……
执行以上命令，如遇到以下报错：
报错内容：DatabaseWrapper objects created in a thread can only be used in that same thread.
DatabaseWrapper objects created in a thread can only be used in that same thread. The object with alias 'default' was created in thread id 2762156319136 and this is thread id 2762243715664.
解决方案：
celery -A celery_tasks worker -l info -P solo -c 10
