# Nginx: /etc/nginx/conf.d/example.conf  (Ubuntu: sites-available/example + symlink)
server {
    listen 80;
    listen [::]:80;
    server_name example.com www.example.com;
    root /var/www/example;
    index index.html;
    location / { try_files $uri $uri/ =404; }

# Apache: /etc/httpd/conf.d/example.conf  (Ubuntu: sites-available/example.conf + a2ensite)
<VirtualHost *:80>
    ServerName  example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example
    <Directory /var/www/example>
        Require all granted
    </Directory>
</VirtualHost>

sudo mkdir -p /var/www/example && echo '<h1>example.com is live!</h1>' | sudo tee /var/www/example/index.html
sudo nginx -t && sudo service nginx reload                  # Nginx
sudo apachectl configtest && sudo service httpd reload      # Apache AL2023/CentOS
sudo apache2ctl configtest && sudo service apache2 reload   # Apache Ubuntu
curl -I http://example.com

If you had put the public IP in server_name in Chapter 8, replace it with the domain names now.
