# include /etc/nginx/sites-enabled/*; # include all the (symlink) files found in sites-enabled folder. do the same as "conf.d" with another approach : you put all your configurations files into a "/etc/nginx/sites-available/" folder, and you put symlinks of a selection of thoses files that you want to use for the site, into "/etc/nginx/sites-enabled/" folder (bad practice : https://serverfault.com/questions/527630/difference-in-sites-available-vs-sites-enabled-vs-conf-d-directories-nginx#answer-870709)
