我正在使用 nginx 将请求传递给我的 flask 应用程序的 gunicorn。出于某种原因，我的站点 example.com 路由正确，但没有其他内容，包括 example.com/index 或 example.com/bot/callback 两者都在我的 views.py 中设置。除了 example.com 之外的所有路由都返回 404。
我认为这是我的 nginx 设置的问题，因为 nginx 访问日志记录了我的请求，但 gunicorns 访问日志仅显示对“/”的请求。/etc/nginx/sites-available/example.com (基于 gunicorn 的例子)

stopsignal=INT
我在这里想念什么？谢谢你的帮助。

所有其他日志都是空的，包括 nginx_error。
所有 worker 退出都是因为我重新启动或停止并启动了服务。

显然我的网站仍然以某种方式将 nginx 错误发送到/var/log/nginx/error.log
/var/log/nginx/error.log
2015/12/17 12:56:57 [emerg] 14404#0: "worker_processes" directive is not allowed here in /etc/nginx/sites-enabled/example.com:1
请您参考如下方法:
除非您在 nginx 或 gunicorn 日志中提供任何日志消息，否则这些问题总是很难弄清楚。您可能会很快找到那里的问题。
听起来 nginx 正在工作，但没有正确地将请求代理到您的 gunicorn 服务器。我想问题出在 upstream_app_server nginx 指令...看起来它没有正确连接到 gunicorn。尝试将其更改为:
upstream app_server {
server 127.0.0.1:8001 fail_timeout=0;
}
如果不是这种情况，请根据对您的应用的评论提供这些文件的内容:
/var/www/example.com/logs/nginx_error
/var/www/example.com/logs/gunicorn_error
您很可能有不止一个配置错误。该过程是检查错误日志，修复错误，然后尝试应用程序，然后如果应用程序不工作，请检查错误日志以查找下一个错误:)。
