騰訊雲服務器部署flask：一

app.py

from flask import Flask,jsonify
app = Flask(__name__)

app.route("/index")
def index():
    print("進入函數")
    return "hello world"


if __name__ == '__main__':
    app.run(debug=True,host="0.0.0.0")

不能訪問

 原因一：防火牆未關閉

service firewalld stop  關閉防火牆

systemctl status firewall  狀態為關閉狀態

(flask_mini) [root@VM_0_13_centos order]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

 原因二：雲服務器的安全組，為開啟指定端口

flask的app訪問，需要加上app(host="0.0.0.0",port=xxxxx)才可以

通過實例的公網ip加指定端口，訪問獲得輸出字符串 hello world
