title: mac apache start in a terminal failed
body: <p>I want to start Apache in Mac. If I make web sharing enable by checking in <code>system prefs -&gt; web sharing</code>, Apache works. But if I input command in terminal: <code>sudo apachectl start</code>, Apache  doesn't start. In this case, when run <code>http://localhost</code> in Safari, it always said <code>The requested URL / was not found on this server.</code> In both cases, I used the default <code>httpd.conf</code>. </p>
  
  <p>Therefore, How can I start Apache and make it work in Mac by inputting command in a terminal instead of by the graphical config window of mac itself? I prefer to command in a terminal.</p>
  
  <p>Thank you.</p>
