title: how to manually restart or stop virtuoso from commandline
body: <p>I have a new installed Virtuoso (from github > 7.2.4) on a <code>Debian jessie</code> system. <strike>It starts properly after boot.</strike></p>
  
  <p>How to stop, start, and restart manually the virtuoso web server? <strike>It starts after reboot.</strike> How can this be achieved from the command line? </p>
  
  <p><strike>How is the automatic restart after boot done? Does it use <code>/etc/init.d/</code> or <code>systemd</code>?</strike></p>
  
  <p>I cannot find files, neither in <code>systemd</code> nor in <code>service</code>? it seems possible to enable in <code>systemd</code> (on a different <code>Debian stretch</code> box), but not on <code>Debian jessie</code>. </p>
  
  <p>thank you for help!</p>
