   server {
   listen 443;
   ssl on;
   ssl_certificate /etc/ssl/domain.pem;
   ssl_certificate_key /etc/ssl/domain.key;
   root /path/to/webroot;
   server_name domain.com;
   }
   access_log /var/log/nginx/nginx.vhost.access.log;
   error_log /var/log/nginx/nginx.vhost.error.log;
   location / {
   root /var/www/;
   root  /home/www/public_html/domain.com/public/;
   index index.html;
