Question

为什么带有 mod_wsgi 的 Apache 强制下载 .py 文件而不是执行它们？

我正在尝试运行 Django，但遇到的第一个问题是 .py 文件无法执行。

我正在关注这里的文档https://docs.djangoproject.com/en/4.0/howto/deployment/wsgi/modwsgi/

• 我正在运行 Ubuntu 20.04.3 LTS
• libapache2-mod-wsgi-py3 已安装并启用
• apachectl configtest语法正确
• 所有文件均归www-data:www-data
• .py 文件是chmod +x
• /var/log/apache2/access.log是空的

/var/log/apache2/error.log包含：

Apache/2.4.41 (Ubuntu) mod_fcgid/2.3.9 OpenSSL/1.1.1k mod_wsgi/4.6.8 Python/3.8 已配置 - 恢复正常操作

根目录中的 .htaccess 文件有

RewriteEngine on
ServerSignature Off

/var/www/html/example.com/public_html 的目录如下：

这是我所看到的；单击 .py 文件会强制下载它。

/etc/apache2/sites-available/default-ssl.conf：

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/html

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        SSLEngine on

        SSLCertificateFile  /etc/ssl/certs/ssl-cert-snakeoil.pem
        SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key

        <FilesMatch "\.(cgi|shtml|phtml|php)$">
                SSLOptions +StdEnvVars
        </FilesMatch>
        <Directory /usr/lib/cgi-bin>
                SSLOptions +StdEnvVars

WSGIScriptAlias没有提供用于单击和查看 Python 服务的方法，您应该使用 Python 定义的路由（路径）来访问您的应用程序。打开.py文件链接可能会通过静态文件服务而不是 WSGI。

因为你将 WSGI 应用程序挂载在根目录，尝试打开 /而不是/contact看看它是否有效。
