3.3Session复制
在Tomcat集群中实现session同步，可以通过session共享和复制来实现，下面以session复制来实现session同步。
3.3
3.3.1编辑hosts文件
注销hosts文件里的回环地址127.0.0.1
3.3.2Session复制配置
在所有Tomcat实例中修改server.xml的配置。
1）编辑server.xml文件
#vi/usr/local/tomcat01/conf/server.xml
2）添加配置
在后面加上以下配置。
Tomcat01:
channelSendOptions="8">
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
address="228.0.0.4"
port="45564"
frequency="500"
dropTime="3000"/>
address="tomsrv01"
port="4000"
autoBind="100"
selectorTimeout="5000"
maxThreads="6"/>
filter=""/>
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
Tomcat02
