Установка Nginx 

####Статический сайт

apt install nano nginx -y

Давайте поправим defalt config

nano /etc/nginx/sites-available

server {
listen 80;
server_name staticsite.geekslore.ru;

location / {
root /var/www/html; # Directory containing static files
index index.html index.htm;
try_files $uri $uri/ =404; # Return 404 if the file is not found
}
}

Сраничку можно сделать такую

nano /var/www/html

<!doctype html>
<html lang="ru">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
