在Apache Tomcat 7设置redis作为session store

在Apache Tomcat 7设置redis作为session store

redis已经有组件支持直接在tomcat7中设置下将redis作为tomcat默认的session存储器，下面介绍下配置过程

1.从http://redis.io/下载redis，按照redis服务端

wget http://download.redis.io/redis-stable.tar.gz tar xvzf redis-stable.tar.gz
cd redis-stable
make

2.启动redis

cd RedisDirectory/src
./redis-server --port 6379

3.从http://tomcat.apache.org/download-70.cgi下载tomcat7，按照tomcat7

4.从https://github.com/xetorthio/jedis/downloads下载jedis作为java的redis客户端，从https://github.com/jcoleman/tomcat-redis-session-manager/downloads下载tomcat的redis session manager插件，从http://commons.apache.org/proper/commons-pool/download_pool.cgi下载apache的common pool包，将这几个jar包拷贝到tomcat7的lib目录下

5.修改tomcat的conf下的context.xml文件，添加或者修改下面的配置

<Valve className="com.radiadesign.catalina.session.RedisSessionHandlerValve" />
<Manager className="com.radiadesign.catalina.session.RedisSessionManager"
host="localhost" <!-- optional: defaults to "localhost" -->
port="6379" <!-- optional: defaults to "6379" -->
database="0" <!-- optional: defaults to "0" -->
maxInactiveInterval="60" <!-- optional: defaults to "60" (in seconds) --> />

6.重启tomcat后就可以看到session存储到redis上了。
