安裝tomcat，jdk，memcache等步驟省略。下面說說tomcat服務中配置memcache的session共享
首先下載tomcat支撐memcache的jar包
具體包名爲kryo-1.04.jar memcached-session-manager-tc6-1.5.1.jar kryo-serializers-0.9.jar minlog-1.2.jar memcached-2.5.jar msm-kryo-serializer-1.5.1.jar memcached-session-manager-1.5.1.jar reflectasm-1.01.jar
並把這些jar包放到tomcat的lib目錄下/usr/local/tomcat/lib
修改tomcat的context.xml配置文件
在<Context>下添加配置
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:172.17.11.242:11211,n2:172.17.11.243:11211"
sticky="false"
sessionBackupAsync="false"
lockingMode="all"
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
前提是memcache要配置正確使用，重啓tomcat即可
