下载完成后拷贝到$TOMCAT_HOME/lib中

修改两tomcat的context.xml:

<Context>  

    <!-- Default set of monitored resources -->  
    <WatchedResource>WEB-INF/web.xml</WatchedResource>  

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->  
    <!-- 
    <Manager pathname="" /> 
    -->  

    <!-- Uncomment this to enable Comet connection tacking (provides events  
         on session expiration as well as webapp lifecycle) -->  
    <!-- 
    <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" /> 
    -->  

  <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />  
  <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"  
   host="10.10.49.20"  
   port="6379"  
   database="0"  
   maxInactiveInterval="60" />  
</Context>

在tomcat/webapps/test放一个index.jsp

<%@ page language="java" %>  
<html>  
  <head><title>TomcatA</title></head>  
  <body>  

    <table align="centre" border="1">  
      <tr>  
        <td>Session ID</td>  
        <td><%= session.getId() %></td>  
      </tr>  
      <tr>  
        <td>Created on</td>  
        <td><%= session.getCreationTime() %></td>  
     </tr>  
    </table>  
  </body>  
</html>  
sessionID:<%=session.getId()%>   
<br>   
SessionIP:<%=request.getServerName()%>   
<br>   
SessionPort:<%=request.getServerPort()%>   
<%   
//为了区分，第二个可以是222  
out.println("This is Tomcat Server 1111");   
%>
