JBoss EAP 6.4 설치

JBoss EAP 6.4 설치에 대해 다룬다. JBoss EAP 6.4 설치는 GUI와 Text 기반 설치 두가지를 지원 한다. 여기서는 Linux 터미널에서 Text 기반 설치에 대해서 다룬다.

사전준비

JBoss EAP 6.4 를 설치하기 위해서는 JDK 1.7 이상 필요하다. JDK 1.6도 지원한다고 되어 있지만 현시점(2016. 06) 에서 1.6은 너무나 구형이라 권장하지 않는다.

설치를 위해서는 설치 파일이 필요한데, zip 파일과 installer 파일 형태로 제공된다. zip 파일은 그냥 압축해제하면 되지만 installer 는 인스톨 과정을 거쳐야 한다. 여기서는 installer를 이용한 설치에 대해서만 다룬다.

설치

설치 레이아웃은 다음과 같다.

JBOSS_HOME: /opt/EAP-6.4.0
JAVA_HOME: /opt/jdk1.8.0_40

JBoss EAP 6.4 의 인스톨 파일은 jboss-eap-6.4.0-installer.jar 이다. Text 기반으로 설치를 위해서는 다음과 같이 명령어를 쳐주면 시작된다.

~]$ java -version
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

JBoss 5 MySQL Replication 접속

만일 MySQL 이 Replication 되어 있다고 한다면 Master 는 read/write 를 Slave 는 read Only 만 하도록 접속을 하고 싶을 것이다. MySQL Connector/J 의 최신버전은 이러한 접속을 지원 한다.

다음은 MySQL Replication 접속을 위한 mysql-ds.xml 예제다.

‘connection-url’, ‘driver-class’ 을 유심히 봐야 한다.

mysql-ds 에서의 설정은 MySQL 의 접속을 이중으로 하도록만하고 실제 쿼리를 분기하기 위해서는 DAO 에서 @Transactional(readOnly=true) 를 주어야 한다. 이 어노테이션은 읽기만을 하다는 것을 알려주고 이는 MySQL Slave 에 접속하게 된다.

각 메소드마다 어노테이션을 주기 싫다면 AOP 를 이용하는 방법도 있다.

	<!-- required to connect Slave Server only for get* method on MySQL Replication  -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">    
        <tx:attributes>      
            <tx:method name="*" propagation="REQUIRED"/>     
            <tx:method name="get*" read-only="true"/>    
        </tx:attributes>    
    </tx:advice>    
           
    <aop:config>    
        <aop:pointcut expression="execution (* com.sbhyun.service.*.*(..))" id="services"/>       
        <aop:advisor advice-ref="txAdvice" pointcut-ref="services"/>    
    </aop:config>

<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:attributes>

<tx:method name="*" propagation="REQUIRED"/>

<tx:method name="get*" read-only="true"/>

</tx:attributes>

</tx:advice>

<aop:config>

<aop:pointcut expression="execution (* com.sbhyun.service.*.*(..))" id="services"/>

<aop:advisor advice-ref="txAdvice" pointcut-ref="services"/>

</aop:config>

service 클래스에 get* 메소드들에는 자동으로 read-only=true 가 설정된다. 이렇게 되면 쿼리를 보낼때마다 Slave 서버에 보내게 되어 쿼리연산이 분산된다.

JBoss EAP 5 MySQL JNDI 설정

JNDI 는 자바 애플리케이션 서버라면 거의 다 지원하는 기능이다. 이는 특정한 자원의 접근을 디렉토리 접근하듯이 하도록 해준다. 여기서 자원이라면 대부분 외부 서버에 있는 저장소들을 말한다.

MySQL, PostgreSQL, Oracle, MS SQL 등 외부 저장소에 접속할때마다 저수준의 드라이버를 올리고 인증을 넣는게 아니라 자바 애플리케이션이 구동되면서 접속하을 해놓고 이것을 디렉토리화해서 올려놓으면 자바 애플리케이션에서는 이 디렉토리에 접근하는 것만으로 외부자원에 접속이 끝이 나게 되어 간편해진다.

이 글은 JBoss EAP 5 MySQL JNDI 설정에 관한 글이다.

MySQL Connector/j

MySQL에서는 자바 애플리케이션을 위해서 접속 드라이버를 제공한다. jar 파일로 작성되 배포되고 있어 다운받아서 지정된 위치에 넣기만 하면 된다.

JBoss EAP 5 는 글로벌 library 디렉토리, Node Library 디렉토리가 존재하는데 node 디렉토리에 다운받아 넣는다. 다시말하면, Jboss EAP 5 의 경우에, jboss-as/server 아래에보면 all, default, production, standard 등의 디렉토리가 보이는데 이걸 node 라고 한다. 여기서 나는 all node 에 lib 디렉토리에 MySQL Connector/J 를 넣어주면 된다.

현 시점에서의 버전은 5.1.39 이다.

]# mv mysql-connector-java-5.1.39-bin.jar $JBOSS_HOME/server/all/lib/

1	]# mv mysql-connector-java-5.1.39-bin.jar $JBOSS_HOME/server/all/lib/

MySQL DataSource

이제 JBoss 에 MySQL DataSource 를 설정해준다. 앞에서 잠깐 말했지만 특정 node 에 설정을 해주게되는데 나는 all 노드에 설정을 할 것이다.

일단 mysql-ds.xml 파일을 다음과 같이 작성한다.

<?xml version="1.0" encoding="UTF-8"?>

11번째 줄이 아주 중요하다. JNDI 이름인데, 이 이름을 가지고 자원을 호출하게 된다.
12번째 줄은 접속 서버 정보이다. 호스트네임이나 IP주소, 접속 데이터베이스명을 적어주면 된다. Unicode 와 CharacterEncoding 은 옵션으로 MySQL 서버와 맞게 설정해 주어야 한다.
14번, 15번 줄은 접속을 위한 인증정보를 적어준다.

이걸 mysql-ds.xml 로 저장한 후에 $JBOSS_HOME/server/all/deploy/ 디렉토리에 넣으면 된다.

애플리케이션 WEB-INF/jboss-web.xml 작성

자바 애플리케이션을 작성할때에 WEB-INF 디렉토리를 만나게 된다. Deployment Descriptor 로 정의되는 web.xml 파일이 위치하는 디렉토리다. 여기에 jboss-web.xml 파일을 다음과 같이 작성한다.

<!DOCTYPE jboss-web PUBLIC
   "-//JBoss//DTD Web Application 5.0//EN"
   "http://www.jboss.org/j2ee/dtd/jboss-web_5_0.dtd">

12,13 줄이 아주 중요하다. JNDI 명을 적어주는데, 앞에 mysql-ds.xml 파일에서 설정한 이름만 적어주는게 아니라 jdbc, java: 등을 함께 적어준다. 이거 의외로 안 적어주고 안된다는 사람이 많으니 주의해서 적어주자.

애플리케이션 WEB-INF/web.xml 작성

Deployment Descriptor 파일로 불리우는 web.xml 파일에 다음과 같은 내용을 추가해준다.

<web-app>
....
  <resource-ref>
    <description>MySQL DataSource</description>
    <res-ref-name>jdbc/MySQLDS</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
  </resource-ref>
....
</web-app>

<web-app>

....

<resource-ref>

<description>MySQL DataSource</description>

<res-ref-name>jdbc/MySQLDS</res-ref-name>

<res-type>javax.sql.DataSource</res-type>

<res-auth>Container</res-auth>

</resource-ref>

....

</web-app>

5줄 에 JNDI 이름을 적어준다. jdbc/ 를 꼭 붙여준다.

여기까지가 JNDI 설정에 관한 것이다. 이 이상은 프로그래머가 사용하는 ORM 에 따라서 JNDI 호출 방법이 달라진다. 하지만 JBOSS 에서 JNDI가 잘 설정되어 있는지를 살펴볼 수있다.

root Context 설정

이제 애플리케이션에서 JNDI를 설정해 보면 다음과 같다.

<!-- Root Context: defines shared resources visible to all other web components -->
	<tx:annotation-driven  />
	
	<!-- enable autowire -->
	<context:annotation-config/>

	<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
		<property name="jndiName" value="java:comp/env/jdbc/MySQLDS" />
		<property name="resourceRef" value="true" />		
	</bean> 
	
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>

<tx:annotation-driven />

<context:annotation-config/>

</bean>

<bean id="transactionManager"

class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

</bean>

jndiName 설정을 어떻게 하는지 주의깊게 봐야 한다.

확인하기

설정한 JNDI가 잘 설정되었는지는 맨 처음 JBoss 를 시작할때에 로그에 나온다.

이것은 JNDI 설정 파일을 읽었을 뿐 실제로 접속이 잘되는지를 나오지 않는다. 이는 JBoss Admin Console 를 통해서 가능하다.

위 그림과 같이 Test Connection 을 클릭하면 접속 테스트를 해준다.

위 그림을 보면 Status 가 성공으로 나와서 접속 성공한으로 착각하는데, 이것은 Test Connection 명령이 성공했다는 것이고 그에 대한 결과는 그 아래에 위와같이 나온다. 위 경우에 접속 실패.

이것저것 문제를 해결한 후에 다시 Test Connection 을 하고 성공하면 설정이 정상적으로 된것이다.

TCP 기반 JBoss 5 Clustering 하기

AWS EC2 에서 JBoss EAP 5.2 를 설치하고 운영할때에 보통 클러스터링을 설정하게 된다. 문제는 JBoss EAP 5.2 에서 클러스터링은 JGroup 을 기반으로 작성되어 있다. 중요한 것은 클러스터링을 할때에 Multicast UDP 를 사용한다는 것인데, AWS EC2 에서는 Multicast 자체를 지원하지 않는다. 따라서 JBoss EAP 5.2 를 AWS EC2 에서 운영하면서 클러스터링을 기본 설정값으로 설정하고 실행시키면 클러스터링이 되지 않는다.

이럴때 TCP 를 이용하면 가능해진다. 이 포스트는 AWS EC2 에서 TCP 기반 JBoss Clustering 에 관련된 내용이다.

MPING을 TCPPING으로 바꾸기

Cluster 의 프로토콜 설정은 다음의 파일에 정의되어 있다.

deploy/cluster/jgroups-channelfactory.sar/META-INF/jgroups-channelfactory-stacks.xml

여기에 TCP 스택 부분에 보면 MPING 설정부분을 코멘트처리하고 TCPPING부분을 언코멘트해준다.

    <stack name="tcp"
           description="TCP based stack, with flow control and message bundling.
                        TCP stacks are usually used when IP multicasting cannot
                        be used in a network, e.g. because it is disabled (e.g.
                        routers discard multicast)">
        <config>

                      <!-- Alternative 1: multicast-based automatic discovery. -->
            <!--<MPING timeout="3000"
                   num_initial_members="3"
                   mcast_addr="${jboss.jgroups.tcp.mping_mcast_addr:230.11.11.11}"
                   mcast_port="${jgroups.tcp.mping_mcast_port:45700}"
                   ip_ttl="${jgroups.udp.ip_ttl:2}"/> -->
            <!-- Alternative 2: non multicast-based replacement for MPING. Requires a static configuration
                 of *all* possible cluster members. -->
            <TCPPING timeout="3000"
                     initial_hosts="${jboss.jgroups.tcp.tcpping.initial_hosts:localhost[7600],localhost[7601]}"
                     port_range="1"
                     num_initial_members="3"/>

<stack name="tcp"

description="TCP based stack, with flow control and message bundling.

TCP stacks are usually used when IP multicasting cannot

be used in a network, e.g. because it is disabled (e.g.

routers discard multicast)">

<!--<MPING timeout="3000"

num_initial_members="3"

mcast_addr="${jboss.jgroups.tcp.mping_mcast_addr:230.11.11.11}"

mcast_port="${jgroups.tcp.mping_mcast_port:45700}"

ip_ttl="${jgroups.udp.ip_ttl:2}"/> -->

<!-- Alternative 2: non multicast-based replacement for MPING. Requires a static configuration

of *all* possible cluster members. -->

<TCPPING timeout="3000"

initial_hosts="${jboss.jgroups.tcp.tcpping.initial_hosts:localhost[7600],localhost[7601]}"

port_range="1"

num_initial_members="3"/>

여기서 핵심이 jboss.jgroups.tcp.tcpping.initial_hosts:localhost[7600],localhost[7600] 부분이다. 이부분은 도메인을 입력해줘야 하는데, 대부분 /etc/hosts 파일에 아이피와 짧은 도메인명으로 정의를 해준다.

이렇게 주석을 해제해준 상태에서 JBOSS 옵션으로 -Djboss.jgroups.tcp.tcpping.initial_hosts=node1[7600],node2[7600] 을 주게 되면 두개의 node 가 TCPPING 으로 묶이게 된다.

Cache 매니저에서 jgroup 스택 프로토콜 바꾸기

이것은 다음의 파일에 정의 되어 있다.

deploy/cluster/jboss-cache-manager.sar/META-INF/jboss-cache-manager-jboss-beans.xml

이 파일에서 jboss.default.jgroups.stack:udp 를 jboss.default.jgroups.stack:tcp 로 모두 교체해준다.

하지만 이 방법외에도 JBOSS 옵션으로 -Djboss.default.jgroups.stack=tcp 를 정의해주고 인스턴스를 시작해주면 적용된다.

JBoss Messaging 을 TCP 로 바꾸기

JBoss Messaging 을 TCP 로 바꾸기 위해서 다음 파일을 열어서 다음과 같이 변경해 준다.

- <attribute name="ControlChannelName">jbm-control</attribute>
- <attribute name="DataChannelName">jbm-data</attribute>
+ <attribute name="ControlChannelName">tcp</attribute>
+ <attribute name="DataChannelName">tcp</attribute>

- <attribute name="ControlChannelName">jbm-control</attribute>

- <attribute name="DataChannelName">jbm-data</attribute>

+ <attribute name="ControlChannelName">tcp</attribute>

+ <attribute name="DataChannelName">tcp</attribute>

이 옵션 변경은 커맨드라인으로 제공하지 않기 때문에 반드시 수동으로 이 파일을 편집해 줘야 한다.

JBOSS 시작 옵션으로 설정하기

위 파일들을 바꾸는 대신에 다음과 같이 시작과 같은 옵션만으로 TCPPING 으로 바꿀 수 있다.

JBOSS_OPTS="$JBOSS_OPTS -Djboss.messaging.ServerPeerID=2"
JBOSS_OPTS="$JBOSS_OPTS -Djboss.service.binding.set=ports-01"
JBOSS_OPTS="$JBOSS_OPTS -Djboss.partition.name=systemV"
JBOSS_OPTS="$JBOSS_OPTS -Djboss.default.jgroups.stack=tcp"
JBOSS_OPTS="$JBOSS_OPTS -Djboss.jgroups.tcp.tcpping.initial_hosts=192.168.96.30[7700],192.168.96.31[7701]"
JBOSS_OPTS="$JBOSS_OPTS -Djboss.jgroups.tcp.tcp_port=7600"
JBOSS_OPTS="$JBOSS_OPTS -Djboss.jgroups.bind.address=192.168.96.30"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.messaging.ServerPeerID=2"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.service.binding.set=ports-01"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.partition.name=systemV"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.default.jgroups.stack=tcp"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.jgroups.tcp.tcpping.initial_hosts=192.168.96.30[7700],192.168.96.31[7701]"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.jgroups.tcp.tcp_port=7600"

JBOSS_OPTS="$JBOSS_OPTS -Djboss.jgroups.bind.address=192.168.96.30"

이 옵션 설정은 매우 중요하다.

먼저, jboss.messaging.ServerPeerID 는 반드시 Cluster 내에서 유일해야 한다. 중복되면 서버 시작시에 오류갈 발생된다.

jboss.service.binding.set 은 default 포트를 기준으로 상대적으로 포트를 할당한다. default 는 각종 서비스 포트에 기본 값으로 Cluster 의 경우에는 7600 포트, HTTP 는 8080 이다. ports-01 은 default 보다 100 을 더해서 Cluster 는 7700, HTTP 는 8180 이된다.

위 jboss.service.binding.set 은 jboss.jgroups.tcp.tcp_port 와 혼동이 될 수 있다. 예를들어 ports-01 인상태에서 tcp_port=7600 으로 했다면 100을 더해서 7700 이 된다. 하지만 ports-01 인 상태에서 tcp_port=7700 이면 실제 Cluster TCP 포트는 100을 더한 7800 이 된다. 결론적으로 tcp_port 의 실제 값은 지정한 값에 binding.set 값을 더한 값으로 된다.

jboss.jgroups.tcp.tcpping.initial_hosts 는 binding.set 과 tcp_port 값을 더한 포트 값을 적어주면 된다. 왜냐하면 이게 실제로 사용되어지는 포트가 되니까 결국에는 이곳의 포트값은 실제로 서버에서 사용되어지는 Cluster Port 값을 적으면 된다.

주의사항

이 설정을 테스트 하기위해서는 서로 다른 머신이 있어야 한다. 같은 서버상에 인스턴스를 두개를 실행시켜서하면 안된다. 반드시 서로 다른 서버에 인스턴스와 테스트를 해야지 성공한다. 이유는 아직 나도 잘 모르겠다.
