Flask 应用程序 IP 重定向在 Ubuntu 上不起作用

Question

我有一个基于 Flask 的网站，当我在本地 PC @ localhost 上运行时工作正常。 我将应用程序克隆到最近构建的 Ubuntu PC 中，并尝试在那里托管网站。 我安装了 Apache2 并设置了conf文件@（ sudo nano /etc/apache2/sites-available/000-default.conf ）如下：

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com
        
ServerName 10.11.220.58

        ServerAdmin webmaster@localhost
        #DocumentRoot /var/www/html
        #DocumentRoot /home/user_name/imageFIFA/frameworks.ai.image-inference

        WSGIScriptAlias / /home/user_name/imageFIFA/frameworks.ai.image-inference/app.wsgi
        <Directory /home/user_name/imageFIFA/frameworks.ai.image-inference>
                Order allow,deny
                Allow from all
        </Directory>

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog /home/user_name/imageFIFA/frameworks.ai.image-inference/logs/error.Log
        CustomLog /home/user_name/imageFIFA/frameworks.ai.image-inference/logs/acess.log comb>

我在 flask 项目文件夹（/home/user_name/imageFIFA/frameworks.ai.image-inference）文件中创建了 app.wsgi，如下所示：

import sys

sys.path.insert(0,'/home/user_name/imageFIFA/frameworks.ai.image-inference')

from interceptor import app as application

我的 flask 位于

/home/ad_pgooneti/imageFIFA/frameworks.ai.image-inference

当我运行我的前端 flask 应用程序并使用 wget 测试响应时，我得到以下信息：

--2022-09-17 12:24:36--  http://localhost:5000/
Resolving localhost (localhost)... 127.0.0.1, ::1

2022-09-17 12:24:36 (236 MB/s) - 'index.html' saved [8943/8943]

但是如果我使用wget 10.11.220.58的服务器IP地址，我得到以下信息：

--2022-09-17 12:29:43--  http://10.11.220.58/
Connecting to 10.11.220.58:80... connected.
HTTP request sent, awaiting response... 403 Forbidden
2022-09-17 12:29:43 ERROR 403: Forbidden.

所以，我觉得重定向不起作用。 Apache2 服务器在我测试其状态时运行良好：

为什么它没有运行有任何帮助吗？ Flask 应用程序在默认端口 5000 上运行，但我不确定我应该在 conf 和 app.wsgi 文件中的哪个位置执行此操作。
