title: How exactly does Tomcat run out of CATALINA_HOME and CATALINA_BASE
body: <p>I'm having trouble finding documentation regarding this. After some googling I find that bin, conf,logs, temp, webapps, work are directories that should exist in <code>CATALINA_BASE</code>. </p>
  
  <p>temp, logs, webapps, bin and work I don't have any trouble understanding. </p>
  
  <p>bin I suppose is just another bin folder, if for some reason both <code>CATALINA_HOME</code> and <code>CATALINA_BASE</code> are in PATH, then scripts in both folders will be available for execution.</p>
  
  <p>But how about conf? Will the content of <code>CATALINA_HOME/conf</code> be totally ignored if <code>CATALINA_BASE</code> is set? Suppose I only would need to customize only a few config files pr. <code>CATALINA_BASE</code>, would I still need to keep a complete set of config files in <code>CATALINA_BASE/conf</code>, or could the standard config files in <code>CATALINA_HOME/conf</code> be shared?</p>
  
  <p>And ditto for <code>CATALINA_BASE/lib</code> ... would this work as a "global" lib folder pr. instance? </p>
