The sites-available and sites-enabled directories are missing. Are they needed at all and how to put them?

Question

Nginx

Version 1.14.2.
$: /etc/nginx ls
conf.d koi-utf mime.types nginx.conf uwsgi_params
fastcgi_params koi-win modules scgi_params win-utf
$: /etc/nginx/conf.d ls
default.conf

Answer 1

You throw the config into conf.d with the name .conf, restart nginx and everything works

Answer 2

Look at the includes in nginx.conf- configs can be placed in any directory that is in the corresponding directive.
