Madhav's questions

我目前在 AWS EC2 实例上托管 Django Webapp，为了在生产模式下运行它，我使用 NGINX 和 gunicorn。

我面临的错误是：

无论我做什么，生产服务器似乎都不会更新 urls.py

用于将文件从本地文件传输到实例的应用程序：FileZilla

我为解决该问题而采取的步骤：

1. 删除 urls.py 并重写它

2. 检查其他文件是否也拒绝更新

   第二步的结果：其他文件已成功更新，我使用静态文件和 index.html 进行了测试

3. 使用纳米编辑器检查文件是否在实例中更新

   第 3 步的结果：文件在实例中正确更新，所有更改都被反映

4. 使用（用于开发目的）在实例上运行它python manage.py runserver，并发现使用 runserver 时 urls.py 正在正确更新

其他信息：

1.昨天一切都在正常更新，但突然决定叛逆

2. 我已经使用更新了所有软件包sudo yum install

3. 我已经重新启动了 nginx 和 gunicorn：使用以下命令：

   sudo systemctl start gunicorn

   sudo systemctl enable gunicorn

   sudo systemctl restart nginx

4. 我尝试使用检查错误sudo nginx -t，但没有出现错误

5. 我已经检查了错误日志，使用sudo tail -f /var/log/nginx/error.log，但
   这里也没有显示错误

我该如何解决这个问题？

谢谢

我正在使用letsencrypt，为使用nginx和gunicorn在生产模式下托管的django项目设置ssl

正在使用的操作系统（操作系统）是：amazon Linux 2

每当我尝试运行服务器时，我都会不断获得 amazon Linux 2 默认页面，当我检查错误日志时，我会收到以下错误：

当我运行时sudo nginx -t：我没有收到任何错误

PS：这是我第一次使用letsencrypt和nginx托管ssl，所以如果.conf文件看起来非常集群，我并不抱歉。

任何帮助将不胜感激，谢谢！
