下載tomcat使用redis做爲session存儲的插件
官網地址：https://github.com/jcoleman/tomcat-redis-session-manager，下載tomcat-redis-session-manager-master.zip，上傳至Linux系統，並解壓

編譯構建項目
```
[root@localhost tomcat-redis-session-manager-master]# gradle build -x test copyJars
```
若是發現gradle命令不能識別，請先安裝gradle工具，請參考Linux系統Nginx安裝配置
生成的jar包
拷貝替換jar包
拷貝dist目錄下面全部的jar包及build/libs目錄下的tomcat-redis-session-manager-master-2.0.0.jar包至{tomcat_home} /lib目錄下（兩臺tomcat）

[root@localhost libs]# cp /home/listen/session/tomcat-redis-session-manager-master/dist/*.jar /home/listen/session/tomcat-redis-session-manager-master/build/libs/tomcat-redis-session-manager-master-2.0.0.jar /home/listen/tomcat/apache-tomcat-7.0.52/lib
[root@localhost libs]# cp /home/listen/session/tomcat-redis-session-manager-master/dist/*.jar /home/listen/session/tomcat-redis-session-manager-master/build/libs/tomcat-redis-session-manager-master-2.0.0.jar /home/listen/tomcat/apache-tomcat-7.0.52-02/lib

修改2個tomcat的context.xml配置文件

[root@localhost tomcat]# pwd 
/home/listen/tomcat
[root@localhost tomcat]# vi apache-tomcat-7.0.52/conf/context.xml

內容爲：

能夠看出鏈接的redis爲192.168.75.141:6379github

測試使用Redis實現Tomcat多機的session共享
新建test工程，爲web模式，修改index.jsp的內容爲：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Nginx+tomcat負載均衡+redis會話管理</title>
</head>
<body>
<h1><font color="blue">集羣節點1</font></h1>
    <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>
 <p>
</body>
</html>

第二臺tomcat部署的test工程的index.jsp的內容修改成：web

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Nginx+tomcat負載均衡+redis會話管理</title>
</head>
<body>
<h1><font color="blue">集羣節點2</font></h1>
    <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>
 <p>
</body>
</html>

部署測試session
將兩個test工程分別部署至兩個tomcat實例，而後重啓2個tomcat，啓動Nginx，（Nginx配置可參考Linux系統Nginx安裝配置）而後刷新而後刷新http://192.168.75.141/test/地址
多刷新幾回，便可看到兩臺tomcat的test工程在不一樣的切換，可是session id不變，即實現多機Tomcat使用Redis實現session共享。
