Nginx+tomcat cluster +redis (memcache) session sharing!

The usual way to keep the session:

1 , some agents (such as Nginxip_hash)

1 , using the database to store the session

2 , using cookies to store session

3 , using Redis to store sesssion (Memcache can also)

......

Environment:

192.168.1.220 nginx centos6.6 Port: Version: 1.9.2 192.168.1.224 tomcata centos6.6 Port: 8080 192.168.1.225 TOMCATB centos6.6 Port: 8090 version: jdk:1.7.0_75 Tomcat: 7.0.54 192.168.1.223 Redis 3.0.5 Port: 6379

Configure session hold and test:

nginx.conf配置：upstream www.tomcatcluster.com { zone myapp1 64k; server 192.168.1.224:8080 weight=1 max_fails=2fail_timeout=30s; server 192.168.1.218:8090 weight=1 max_fails=2fail_timeout=30s;}server {       listen 80 default;       server_name  www.tomcat.com;         location / {    proxy_pass http://www.tomcatcluster.com;   }}

Tomcata:TOMCATB

Session hold:

Edit Tomcat configuration file Context.xml (both Tomcata and TOMCATB operations)

1234567891011

<Context><Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve"/><ManagerclassName="com.orangefunction.tomcat.redissessions.RedisSessionManager"   host="192.168.1.223"<!-- Redis地址 -->   port="6379"<!-- Redis端口 -->   paassword="tomcat" <!-- Redis密码 -->   database="0"<!-- 存储Session的Redis库编号 -->   maxInactiveInterval="60"<!-- Session失效的间隔（秒） -->/></Context>mv commons-pool2-2.2.jar  jedis-2.7.2.jar  tomcat-redis-session-manage-tomcat7.jar  /usr/local/tomcat-7.0.54/lib/

How do I test session sessions to maintain?

You can see that although the server changes from Tomcata to TOMCATB, the session creation time has not changed, which completes the session sharing.
