Howtos/Autoindex on nginx

You can activate autoindex on the main server folder (/var/www/html/) and/or home folders (~/public_html/).

~/public_html/

location ~ ^/~(.+?)(/.*)?$ {
    alias /home/$1/public_html$2;
    index index.php index.html index.htm;
    autoindex on; # this feature automatically lists all files in the public_html folder!
}
