部署 Tomcat 1 & Tomcat 2# service httpd stop# cd /tmp# chmod +x jdk-6u27-linux-i586.bin# ./jdk-6u27-linux-i586.bin# mv jdk1.6.0_27/ /usr/local/jdk

部署 Memcache 1 & Memcache 2# tar xf libevent-2.0.15-stable.tar.gz# cd libevent-2.0.15-stable#./configure && make && make install# tar xf memcached-1.4.5.tar.gz# cd 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# memcached-h# memcached-p 11211 -l 192.168.122.40 -u root -m 10 -c 10 -vvv -f 1.2 -n 60 打开监听
部署 Tomcat 1 & Tomcat 2 支持连接 Memcached# cpsession/*.jar/usr/local/tomcat/lib# vim /usr/local/tomcat/conf/context.xml <ManagerclassName="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:192.168.0.115:11211,n2:192.168.0.110:11211" failoverNodes="n1" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" />注意：定义内容要写在<Context></Context>里面#/usr/local/tomcat/bin/shutdown.sh# /usr/local/tomcat/bin/startup.sh
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
