server{
       listen 80 ;
        server_name gofly.sopans.com;
        access_log   / var /log/nginx/ gofly.sopans.com.access.log main;
        location / static {
                root / var /www/html/go-fly; // Own deployment path 
        }        
        location / {
                add_header Access -Control-Allow-Origin * ;
                add_header Access -Control-Allow-Methods ' GET, POST, OPTIONS ' ;
                proxy_pass http: // 127.0.0.1:8081; 
                    proxy_http_version 1.1 ;
                    proxy_set_header X -Real- IP $remote_addr;
                    proxy_set_header Upgrade $http_upgrade;
                    proxy_set_header Connection " upgrade " ;
