下载tomcat--session-manager相应的jar包

--------------------------------------------------------------------------------------------------------------------------------------------------------------------
下载完成后拷贝到$TOMCAT_HOME/lib中
修改两tomcat的context.xml:
单点配置
<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>
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
基于redis的集群配置如下：
<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放一个index.jsp
<%@ page language="" %> <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"); %>
通过访问http://127.0.0.1/index.jsp
可以看到虽然Server从1111变为2222，但session的创建时间没有变化，这就完成了session共享。
