title: Nginx default.conf missing on centOS 7
body: <p>I recently install <code>Nginx</code> on my server lab, after seeing several videos Nginx And The LEMP Stack I saw the teacher navigate to <code>/etc/nginx/conf.d/</code> and vi the <code>default.conf</code>. 
  I try on my server lab but i can't find the <code>default.conf</code> at <code>/etc/nginx/conf.d</code>, the folder was empty but the server is running and i can access the public ip from my internet browser</p>
