Session clustering (udp/tcp), sticky session

※ 세션 클러스터링 기본

- JBoss Node Name

Node 별로 Unique하게 설정: -Djboss.node.name

- jvmRoute

Node별로 jvmRout 또는 instance-id 설정

UseJK=true로 설정

 

- 클러스터링 관련 네트웍 설정

Clustering 방식 설정: -Djboss.default.jgroups.stack

UDP멀티캐스트 주소설정: -Djboss.default.multicast.address

UDP멀티캐스트 포트: 45688 (standalone-ha.xml)

최초 연결할 클러스터 멤버: -Djgroups.tcpping.initial_hosts

TCPPING 설정: standalone-ha.xm

 

- 기본 사용포트 확인

※ 세션 클러스터링 설정

1) TCP / UDP 공통사항

NODE_NAME설정

Node별로 Name을 Unique하게 설정을 한다.

env.sh

-Djboss.node.name=$NODE_NAME"

 

jvmRoute 또는 instance-id 설정

env.properties

... jvmRoute=server1




또는 instance-id 지정










설정파일

<subsystem xmlns="urn:jboss:domain:web:2.1" default-virtual-server="default-host" instance-id="server1" native="true">

useJK 설정

env.properties

... UseJK=true

2) UDP방식 설정

env.sh

export MULTICAST_ADDR=230.1.0.1   # Default로 45688 사용 (standalone-ha.xml)   # jgroups setting export JAVA_OPTS=" $JAVA_OPTS -Djboss.default.jgroups.stack=udp" export JAVA_OPTS=" $JAVA_OPTS -Djboss.default.multicast.address=$MULTICAST_ADDR"

 

3) TCP방식 설정

env.sh

# jgroups setting export JAVA_OPTS=" $JAVA_OPTS -Djboss.default.jgroups.stack=tcp" export JAVA_OPTS=" $JAVA_OPTS -Djgroups.tcpping.initial_hosts=192.168.0.56[7600],192.168.0.56[7700], "

standalone-ha.xml

<stack name="tcp">     <transport type="TCP" socket-binding="jgroups-tcp"/>     <protocol type="TCPPING" socket-binding="jgroups-mping">         <property name="initial_hosts">             ${jgroups.tcpping.initial_hosts:localhost:7600,localhost:7600}         </property>         <property name="port_range">             0         </property>         <property name="timeout">             3000         </property>         <property name="num_initial_members">             3         </property>     </protocol>     <protocol type="MERGE2"/>     <protocol type="FD_SOCK" socket-binding="jgroups-tcp-fd"/>     <protocol type="FD"/>     <protocol type="VERIFY_SUSPECT"/>     <protocol type="pbcast.NAKACK"/>     <protocol type="UNICAST2"/>     <protocol type="pbcast.STABLE"/>     <protocol type="pbcast.GMS"/>     <protocol type="UFC"/>     <protocol type="MFC"/>     <protocol type="FRAG2"/>     <protocol type="RSVP"/> </stack>

※ Sticky Session 설정

env.properties

jvmRoute=server1    # 위에 언급된 instance-id를 통해서도 설정 가능 UseJK=true

※ Application별 클러스터링 설정
