title: unable to connect to system bus: failed to connect to socket /var/run/dbus/system_bus_socket
body: <p>I started to use a new VPS system with ubuntu 12.04 </p>
  
  <p>After following the commands <a href="http://ubuntuforums.org/showthread.php?t=1977769" rel="noreferrer">here</a> I installed php, mysql, apache2 </p>
  
  <p>PHP and apache are working great but when I run :</p>
  
  <pre><code>service mysql start 
  </code></pre>
  
  <p>I get : <code>unable to connect to system bus: failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory.</code></p>
  
  <p>I googled but didn't find enough to help me.</p>
  
  <p><em>There is no /var/run/dbus/ directory and I don't know what I need to create one or even if this is the problem for mysql.</em></p>
