Django-Gunicorn / Nginx-502错误网关

Question

需要有关502 Bad Gateway ngnix / 1.10.3的帮助

我已经使用Nginx / Gunicorn配置了Django应用程序。在我对代码进行一些更改并重新加载服务器之前，它运行良好。

仅供参考：我的settings.py具有ALLOWED_HOSTS = ['*']

错误日志：

更新1：

这是我的Nginx配置。这有什么问题吗？

/ etc / nginx / sites-available / MySite

server {
    listen 80;
    server_name 18.191.255.247;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/ubuntu/www/MySite;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix://home/ubuntu/www/MySite/MySite.sock;
    }
}

如何验证nginx守护程序对项目文件夹（// unix：// home / ubuntu / www / MySite）的权限

Answer 1

尝试手动将代理传递URL设置为端口gunicorn正在服务器上运行项目，例如：

location / {
                proxy_pass         http://localhost:8000;
                proxy_redirect     off;
                proxy_set_header   Host              $http_host;
                proxy_set_header   X-Real-IP         $remote_addr;
                proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
                proxy_connect_timeout 500;
                proxy_read_timeout 600;
        }

Answer 2

是的，存在配置问题

location / {
     include proxy_params;
     proxy_pass http://unix:/home/ubuntu/www/MySite/MySite.sock;
}

/etc/init.d/nginx restart

使用以下命令检查套接字文件的权限

ls -l /home/ubuntu/www/MySite/MySite.sock
