服务器上NGINX和UWSGI的Flask Python应用程序未知行为

标签: python nginx flask ubuntu-18.04 uwsgi

我已经使用Flask Framework开发了Python应用程序,并使用NGINX和UWSGI将其部署在Ubuntu 18.02 Server上。

服务器功能强大,可以轻松处理大量用户,但是当30至40个用户与之连接时,服务器就会开始出现问题。

我检查了日志,没有看到任何应用程序错误,但是从NGINX和UWSGI方面,我看到了以下错误:

  1. 从上游请求超时
  2. 系统找不到套接字文件,或者找不到文件或系统没有读取文件。

(虽然套接字文件也位于/ tmp /目录中)

我无法确定问题的根本原因是权限级别问题还是其他原因?您还可以在下面检查我的配置和ini文件:

这是我的默认nginx和mynginx配置,带有uwsgi.ini详细信息:

default-nginx.config

    user www-data;
    worker_processes auto;
    pid /run/nginx.pid;

    events {
    worker_connections 768;
    multi_accept on;
    }

任何帮助将不胜感激,它已成为我PRODUCTION应用程序上的一个节目停止器。
