Nginx配置

 server {
            listen       80;
                server_name   test.com;

                #charset utf-8

                access_log  /var/log/nodejs_nginx.log;

             location  /  {
                proxy_set_header    X-Real-IP $remote_addr;
                    proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header    Host  $http_host;
                    proxy_set_header    X-Nginx-Proxy true;
                    proxy_set_header    Connection "";

                    proxy_pass  http://127.0.0.1:3000/;
                }
            }

Nginx配置文件测试正常，express启动正常，但是依然是Nginx默认页面
