学习uwsgi+flask启动方式
1 flask创建最简单的框架
2 编写uwsgi.ini
[uwsgi] http=:5001 wsgi-file=/root/PycharmProjects/untitled2/app.py callable=app
3 启动uwsgi

1 flask+uwsgi+nginx
参考：https://www.cnblogs.com/xingxia/p/python_nginx_uwsgi.html
（分清楚是socket模式，还是http模式. 第一次配置nginx,参考的是一篇nginx中socket模式连接的。我前面uwsgi中配置的是http模式。两个配置没有一致。如果第一次配置成功了，我就不会继续去看另外一种配置方式。纸上得来终觉浅，绝知此事要躬行）
nginx扩展学习：https://www.cnblogs.com/chenyanbin/p/12521296.html
2 flask+uwsgi+nginx+supervisor
pipy: https://pypi.org/project/supervisor/ 目前不支持python 3.8。 （文章当时是3月底写的，7月5日更新发现连接里面已经支持python3.8. 看来跟新速度可以）
