Nginx はデフォルトで「/var/www/html」というディレクトリを作っていますが、今回は /var/www/ の配下にドメイン名のディレクトリ、そしてその配下に html というディレクトリを作ります。(イメージ:/var/www/example.com/html)
vpsadmin@xx1-234-56789:/var/www$ sudo mkdir -p example.com
[sudo] password for vpsadmin:
vpsadmin@xx1-234-56789:/var/www$ ls
html meatthezoo.org
vpsadmin@xx1-234-56789:/var/www$ cd example.com
vpsadmin@xx1-234-56789:/var/www/example.com$ sudo mkdir -p html
