Mod_wsgi 守护进程模式不重新加载网页模板答案

【问题标题】：Mod_wsgi daemon mode not reloading web page templatesMod_wsgi 守护进程模式不重新加载网页模板

【问题描述】：

我无法通过触摸位于我的 django 应用程序根目录/应用程序名称中的 wsgi.py 脚本来重新加载 django 模板。

脚本和项目位于/var/www下，所以我需要sudo来执行touch。

我正在运行生产 apache2 服务器，该服务器运行 django 网站，mod_wsgi 处于守护程序模式。我可以收集静态数据并进行迁移，访问数据库（没有权限问题）。我还可以在设置中更改 DEBUG 标志。如果我触摸 wsgi.py，它将按预期将生产站点置于调试状态，但未加载 html。同样，我可以更新静态文件、收集静态文件或修改底层模型并实时查看更改。同样，我可以使用注释代码来检索 swerver 正在运行的守护程序模式。它只是导致问题的模板。设置文件、wsgi.py、statics 和 python 脚本按预期响应。

有人知道如何调试吗？

virtualenv python3.8.12 apache2.4 为python3.8.12编译的mod_wsgi

wsgi.py

import os
import sys

from django.core.wsgi import get_wsgi_application

sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../../")))
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../")))
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../app/")))

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mb.settings')

application = get_wsgi_application()

#def application(environ, start_response):
#    status = '200 OK'

#    if not environ['mod_wsgi.process_group']:
#      output = u'EMBEDDED MODE'
#    else:
#      output = u'DAEMON MODE'

#    response_headers = [('Content-Type', 'text/plain'),
#                        ('Content-Length', str(len(output)))]

#    start_response(status, response_headers)

#    return [output.encode('UTF-8')]

<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 app

【解决方案1】：

出于某种原因，我使用新的 html 而不是 git push 将 scp 复制到目录中。结果？我在带有 -r 标志的 scp 上使用了递归副本。这会自动创建一个子目录。它混淆了守护进程。删除这个子目录解决了这个问题，并且触摸工作正常。
