title: How can I stop a symfony process which is listening on http://127.0.0.1:8000
body: <p>I am trying to run a basic Symfony installation which I generated using this command :</p>
  
  <pre><code>$ symfony new basic
  </code></pre>
  
  <p>When I run the following commands :</p>
  
  <pre><code>$ cd basic
  $ php bin/console server:run
  </code></pre>
  
  <p>I get this error message :</p>
  
  <pre><code>[ERROR] A process is already listening on http://127.0.0.1:8000.
  </code></pre>
  
  <p>I suspect that a previous symfony process is causing this but I have no clue how to stop it.</p>
  
  <p>I'm on a Ubuntu 14.04 machine.
  Any help would be appreciated.</p>
