title: Updating Jenkins on Centos
body: <p>I'm trying to update <code>Jenkins</code> on <code>Centos7</code></p>
  
  <p>When I run <code>service Jenkins status</code> command I can see that Jenkins is active. </p>
  
  <p>When I try to connect to Jenkins using the browser I'm getting this message:       </p>
  
  <blockquote>
    <p>refused to connect to http://*****:8080.</p>
  </blockquote>
  
  <p>I have followed the following steps but it's not working:</p>
  
  <p>1) Run <code>service Jenkins stop</code> command.</p>
  
  <p>2) Replaced <code>Jenkins.war</code> with the new one.</p>
  
  <p>3) Run <code>service Jenkins start</code> command.</p>
