阶段测试
1.访问 index.html 由 Aapche 处理,
2.访问 index.jsp 交给 Tomcat 1 与 Tomcat 2 负载处理,
3.访问 index.jsp 时在 Tomcat 1 与 Tomcat 2 之间进行切换,但是 session_id 也随之变化
部署 Memcache 1 & Memcache 2
# tar xf libevent-2.0.15-stable.tar.gz
# cd libevent-2.0.15-stable
[root@localhost libevent-2.0.15-stable]#./configure && make && make install
# tar xf memcached-1.4.5.tar.gz
# cd memcached-1.4.5
[root@localhost memcached-1.4.5]#./configure && make && make install
# ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5

部署 Tomcat 1 & Tomcat 2 支持连接 Memcached
# cp session/*.jar /usr/local/tomcat/lib
# vim /usr/local/tomcat/conf/context.xml

最终测试
1.访问 index.html 由 Aapche 处理,
2.访问 index.jsp 交给 Tomcat 1 与 Tomcat 2 负载处理,
3.访问 index.jsp 时在 Tomcat 1 与 Tomcat 2 之间进行切换,并且 session_id 不会变化
