Nginx+tomcat+redis Complete Session Sharing

This document records the process of Nginx+redis+tomcat implementing session sharing.

Nginx Installation: http://blog.csdn.net/grhlove123/article/details/47834673

Redis Installation: http://blog.csdn.net/grhlove123/article/details/47783471

Prepare two Tomcat, modify the appropriate port

Name	Ip	Port	Tomcat version	Jdk
Tomcat1	10.10.49.23	8080	7.0.40	1.7.0_25
Tomcat2	10.10.49.15	8081	7.0.40	1.7.0_25

Modify nginx.conf Plus:

    Upstream backend {        server 10.10.49.23:8080 Max_fails=1 fail_timeout=10s;        Server 10.10.49.15:8081 Max_fails=1 fail_timeout=10s;    }

Modify the location of the nginx.conf into

    Location/{        root   html;        Index  index.html index.htm;        Proxy_pass http://backend;     }

Start Nginx.

Download Tomcat-redis-session-manager the corresponding jar package, there are three main:

wget https://github.com/downloads/jcoleman/tomcat-redis-session-manager/ Tomcat-redis-session-manager-1.2-tomcat-7-java-7.jar
wget Http://central.maven.org/maven2/redis/clients/jedis/2.5.2/jedis-2.5.2.jar
wget Http://central.maven.org/maven2/org/apache/commons/commons-pool2/2.0/commons-pool2-2.0.jar

Copy to $tomcat_home/lib when download is complete

Modify the Context.xml of two tomcat:

<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 Eve NTS 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= "/></context>"

Put a index.jsp in tomcat/webapps/test.

<%@ page language= "java"%>
Started Tomcat, found an exception: Com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve class could not find
Open three jar packages respectively, do not have this class, the solution can be consulted:

by visiting http://10.10.49.20/test/

Refresh:
You can see that although server has changed from 1111 to 2222, the session creation time has not changed, which completes the session sharing.
