title: How to change Jenkins config directory?
body: <p>I deployed my <code>Jenkins</code> to <code>Tomcat 7</code>. At that time, my tomcat was running under user <code>root</code> (on <code>CentOS 7</code>). The Jenkins config was placed in <code>/root/.jenkins</code>.</p>
  
  <p>Now I want to run my Tomcat as a different user. The startup resulted in errors obviously because it couldn't access root's home directory.</p>
  
  <p>How can I switch the Jenkins config from root to somewhere accessible by the new user under which Jenkins runs?</p>
