Nginx + varnish configuration for magento site 2 and 1

I have a centos server 7 php7 + nginx + varnish + redis + php-fpm is already installed working with magento to 9 years, I even installed my sites and the server. There is no control panel on the server all installed by me the optimized hand for magento 1 however now have to optimize for both. my server is with varnish on port 80 and nginx on port 8080 and 443. I deleted all magento and reinstalled 3x the problem is not in the magento but server configuration. This setting is working correctly for my magento 1. I am creating another site with magento 2 the same is working I was able to install magento 2 however the screen does not open correctly css and images. I need the best setting for both magentos. I also need to add an additional ip on this same dedicated server.
