下載tomcat-Redis-session-manager相應的jar包
https://page61.ctfile.com/fs/Vtq167749542
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
下載完成後拷貝到$TOMCAT_HOME/lib中
修改兩tomcat的context.xml:
單點配置
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<ValveclassName="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve"/>
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="192.168.254.10"
port="6379"
database="0"
maxInactiveInterval="60"/>
</Context>
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
基於redis的集羣配置如下：
<ValveclassName="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve"/>
<ManagerclassName="com.orangefunction.tomcat.redissessions.RedisSessionManager"
maxInactiveInterval="60"
sentinelMaster="mymaster"
sentinels="127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381,127.0.0.1:26382"/>
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
在tomcat/webapps/ROOT放一個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()%>
<%
//爲了區分，第二個可以是222
out.println("This is Tomcat Server 1111");
%>
通過訪問http://127.0.0.1/index.jsp
可以看到雖然Server從1111變爲2222，但session的創建時間沒有變化，這就完成了session共享。
