if __name__ == '__main__':
    app.run(host="172.xxx.xxx.xx", port=5000, debug=True)

執行測試
python app.py

uwsgi部署：
uwsgi.ini

[uwsgi]
http=172.xxx.xxx.xxx:5000
#pythonpath ：專案目錄
pythonpath=/home/hayley/flask
#callable：具體執行.run方法的那個實體的名字
callable=app
wsgi-file = /home/hayley/flask/app.py
#processes：伺服器開啟的並行程序個數
processes=1
#threads：每個程序等待處理請求的執行緒個數
threads=4
#daemonize ：日誌檔案
daemonize = /home/hayley/flask/conf/uwsgi.log

linux命令：

#開始執行：
uwsgi uwsgi.ini
#停止uwsgi：
pkill -f -9 uwsgi
