title: How to customize the Jenkins url without port number in linux
body: <p>I have a jenkins server as <a href="http://domainname.com:8080" rel="nofollow noreferrer">http://domainname.com:8080</a>
  i want that to be changed to <a href="http://domainname.com/jenkins" rel="nofollow noreferrer">http://domainname.com/jenkins</a></p>
  
  <p>I am not sure in linux how to achieve this.
  URL rewrite seems to be solution for windows.</p>
