nginx未启动Web2PY应用程序

Question

我用 Web2py 框架创建了一个网站。为了在生产中启动它，按照描述使用了uWSGI应用程序和NGiNX服务器此处。

NGiNX和uWSGI都在运行，Web2py也运行，但网站页面打不开。浏览器返回错误“502 网关错误”。请告诉我如何解决这个问题？

文件 /etc/nginx/sites-available/web2py ：

server {
        listen          80;
        server_name     $hostname;
        root html;
        index index.html index.htm;
        location ~* /(\w+)/static/ {
            root /home/www-data/web2py/applications/;
            #remove next comment on production
            #expires max;
        }
        location / {
            uwsgi_pass      unix:///tmp/web2py.socket;
            include         uwsgi_params;
            uwsgi_param     UWSGI_SCHEME $scheme;
            uwsgi_param     SERVER_SOFTWARE    nginx/$nginx_version;
        }
}
server {
        listen 443 default_server ssl;
        server_name     $hostname;
        ssl_certificate         /etc/nginx/ssl/web2py.crt;
        ssl_certificate_key     /etc/nginx/ssl/web2py.key;
        ssl_prefer_server_ciphers on;
        ssl_session_cache shared:SSL:10m;
        ssl_session_timeout 10m;
        ssl_ciphers ECDHE-RSA-AES256-SHA:DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        keepalive_timeout    70;
        location / {
            uwsgi_pass      unix:///tmp/web2py.socket;
            include         uwsgi_params;
            uwsgi_param     UWSGI_SCHEME $scheme;
            uwsgi_param     SERVER_SOFTWARE    nginx/$nginx_version;
        }

}
