说明：

8080、8081分别为tomcat两实例;

11212、11213分别为memcached两实例;

web应用示例工程casdemo部署在tomcat两实例上。

MSM介绍

传统tomcat统一管理tomcat

sticky根据IP直接绑定到该tomcat实例。

no-sticky:会话非粘连模式。客户端的请求是随机分发，多台tomcat实例均会收到请求。

MSM依赖包

spymemcached-2.11.1.jar

reflectasm-1.01.jar

msm-kryo-serializer-1.8.3.jar

msm-javolution-serializer-1.8.3.jar

msm-flexjson-serializer-1.8.3.jar

minlog-1.2.jar

memcached-session-manager-tc8-1.8.3.jar

memcached-session-manager-1.8.3.jar

kryo-serializers-0.11.jar

kryo-1.04.jar

asm-3.2.jar

放到tomcat/lib下

tomcat配置

修改

<Server port="8005" shutdown="SHUTDOWN"><Connector port="8080" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" /><Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /><Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1"> —非必选，只有选择了sticky模式才加入jvmRoute属性。不同的tomcat实例 jvmRoute取值不能相同。例：8080端口的tomcat实例jvmRoute=tomcat1,8081端口的tomcat实例jvmRoute=tomcat2

2.8081

<Server port="9005" shutdown="SHUTDOWN"><Connector port="8081" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" /><Connector port="9009" protocol="AJP/1.3" redirectPort="8443" /><Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2"> —非必选，只有选择了sticky模式才加入jvmRoute属性。不同的tomcat实例 jvmRoute取值不能相同。例：8080端口的tomcat实例jvmRoute=tomcat1,8081端口的tomcat实例jvmRoute=tomcat2
