기본적으로 Tomcat 은 세가지 세션관리자를 제공한다.
|
Standard Manager |
기본 세션 관리자 |
|
Persistant Manager |

세션 클러스터링 설정 방법
1. Multicast Routing 설정
route add -net 224.0.0.0 net netmask 244.0.0.0 dev eth0
2. server.xml 설정

<Manager className="org.apache.catalina.ha.session.BackupManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/>
<Channel className="org.apache.catalina.tribes.group.GroupChannel">

</Sender>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="4001" <!-- 한 서버에 여러 Tomcat를 구동할 경우 Port 번호를 다르게 설정 -->
autoBind="100"
selectorTimeout="5000"
maxThreads="6"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/>
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>
3. wb.xml 설정
4. 확인
