title: sudo apachectl -k start not work on MacOS HIGH SIERRA
body: <p>I've run <strong>sudo apachectl -k start</strong> , but the httpd process wasn't created.
  And when I've run <strong>apachectl configtest</strong> on terminal, it shows me <em>Syntax OK</em>.
  Also I run other commands:</p>
  <blockquote>
  <p>sudo apachectl -k restart  =&gt; httpd not running, trying to start.</p>
  <p>sudo apachectl -k stop =&gt; httpd (pid 1369?) not running</p>
