Here I have shared a script for creating NGINX virtual host with PHP 7.0. NGINX virtual host with 5.x and 7.0 is very similar but only different is php5-fpm.sock location. To create a NGINX virtual host open the configuration files by running this command.
sudo gedit /etc/nginx/sites-available/default
And then copy-pastes this code snippet and modify it by your configuration (information). Then restart your server. And you are ready to go.
See it for creating virtual host with PHP 5.x
