title: Keeping a build process running after Jenkins job
body: <p>I am trying to keep a web process running after the <em>Jenkins</em> job is done. </p>
  
  <p>I looked into <em>ProcessTreeKiller</em> and have tried using <code>BuildId</code> as below, but it doesn't seem to work:</p>
  
  <pre><code>BUILD_ID=dontKillMe /usr/apache/bin/httpd
  </code></pre>
  
  <p>My command (which I want to keep it running):</p>
  
  <pre><code>rails s &amp;
  </code></pre>
  
  <p>How can I fix this issue ? </p>
