请求协助：Flask应用部署至Apache时报Error 10013权限错误

环境信息 #

• Windows 11 x64
• Python 3.10.9、Flask 2.2.2
• Apache 2.4.54、mod_wsgi 4.9.4
• 杀毒软件：ESET 10.0.2045.0

问题描述 #

尝试通过mod_wsgi将Flask HelloWorld应用部署到Apache服务器时，始终报错：Error 10013：An attempt was made to access a socket in a way forbidden by its access permissions。应用可在Werkzeug和WSGIserver正常运行，但部署到Apache后无法启动。

Apache httpd.conf配置 #

LoadFile "C:/users/pvachal/appdata/local/programs/python/python310/python310.dll"
LoadModule wsgi_module "C:/users/pvachal/appdata/local/programs/python/python310/lib/site-packages/mod_wsgi/server/mod_wsgi.cp310-win_amd64.pyd"
WSGIPythonHome "C:/users/pvachal/appdata/local/programs/python/python310"

#WSGIDaemonProcess flaskapp python-path="c:/users/pvachal/appdata/local/programs/python/python310/lib/site-packages"

<VirtualHost *:8000>
#   DocumentRoot "c:/users/pvachal/documents/projekty/flask_app_hello_world"

    <Directory c:/users/pvachal/documents/projekty/flask_app_hello_world>
        <IfVersion < 2.4>
            Order allow,deny
            Allow from all
        </IfVersion>
        <IfVersion >= 2.4>
            Require all granted
        </IfVersion>
    </Directory>

    WSGIScriptAlias / "c:/users/pvachal/documents/projekty/flask_app_hello_world/app.wsgi"

</VirtualHost>

注：WSGI模块已成功加载，VirtualHost监听端口为8000；未加载WSGI模块时Apache可正常显示默认页面。

已尝试的排查操作 #

• 确认端口8000未被占用
• 禁用Internet Connection Sharing (ICS)服务，无变化
• 禁用ESET防火墙及网络保护，无变化
• 通过Python socket模块连接localhost:8000，出现WinError 10061：目标机器主动拒绝连接

Flask应用代码（app.py） #

from flask import Flask, render_template

app = Flask(__name__)
HOST = "localhost"
PORT = 8000

@app.route("/")
def home():
    return render_template("index.html")

if __name__ == "__main__":
    app.run(debug=True, host=HOST, port=PORT)

注：index.html为仅包含HelloWorld标题的简单页面。

app.wsgi代码 #

#! C:/Users/pvachal/AppData/Local/Programs/Python/Python310/python.exe

import sys

sys.path.insert(0, "c:/users/pvachal/documents/projekty/flask_app_hello_world")

activate_this = "c:/users/pvachal/documents/projekty/flask_app_hello_world/venv/scripts/activate_this.py"
with open(activate_this) as file_:
    exec(file_.read(), dict(__file__=activate_this))

from app import app as application

提问 #

已排查一周仍未解决，推测可能与网络权限相关，请问问题出在哪里？如何成功将Flask应用部署到Apache服务器？
