mod_cluster 사용을 위한 설정 가이드

module download link  (http://mod-cluster.jboss.org/downloads/1-2-0-Final)

• apache 버전과 mod_cluster 버전 확인 필요

1. mod copy
   mod_advertise.so
   mod_manager.so
   mod_proxy_cluster.so
   mod_slotmem.so
   기본적으로 jboss eap 설치 하고 나면 F:\app\was\jboss\modules\system\layers\base\native\lib64\httpd\modules  의 경로에 살펴 보면
   httpd mod 관련 제공해주는 so 파일들이 존재 한다.
   해당 파일을 webserver module 폴더로 복사 하여 사용한다.
2. mod_cluster.conf 

          샘플 파일은 F:\app\was\jboss\modules\system\layers\base\native\etc\httpd\conf 경로의 mod_cluster.conf 파일을 참조 하여 작성 하면 된다.

          

mod_cluster.conf sample

# mod_proxy_balancer should be disabled when mod_cluster is used LoadModule slotmem_module modules/mod_slotmem.so LoadModule manager_module modules/mod_manager.so LoadModule proxy_cluster_module modules/mod_proxy_cluster.so LoadModule advertise_module modules/mod_advertise.so MemManagerFile "@installroot@/var/cache/mod_cluster" <IfModule manager_module>   Listen 6666   <VirtualHost *:6666>     <Directory />       Order deny,allow       Deny from all       Allow from 127.0.0.1     </Directory>     ServerAdvertise on     EnableMCPMReceive     <Location /mod_cluster_manager>       SetHandler mod_cluster-manager       Order deny,allow       Allow from all    </Location>   </VirtualHost> </IfModule> NameVirtualHost *:80 <VirtualHost *:80>    <Location />       Order deny,allow       Allow from all    </Location>    <Location /mod_cluster_manager>       SetHandler mod_cluster-manager       Order deny,allow       Allow from all    </Location> </VirtualHost>

3. instance-id  (domain mod 기준 작성) standalone 의 경우도 별반 차이가 없다. jboss.server.name 변수가 틀림
   profile 범위의 default-host subsystem 위치에 instance-id 작성

domain.xml 

<subsystem xmlns="urn:jboss:domain:web:2.2" default-virtual-server="default-host"  instance-id="${jboss.server.name}" native="false">                 <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>                 <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>                 <virtual-server name="default-host" enable-welcome-root="true">                     <alias name="localhost"/>                     <alias name="example.com"/>                 </virtual-server>             </subsystem>

** 주의 사항

같은 네트워크 내에 JBOSS EAP 인스턴스가 존재하는 경우 멀티캐스트 주소을 구분을 해주어야 한다.

tcp 통신으로도 클러스터링 구현 가능

                <remote-destination host="localhost" port="25"/>

            </outbound-socket-binding>

        </socket-binding-group>

start shell 에 -Djboss.modcluster.multicast.address=224.10.1.1 와 같은 파라미터을 등록 하여 사용 한다.

multicast-address 주소을 직접 변경 해도 무방.
