JBoss EAP 設置 Domain Mode

JBoss EAP 設置 Domain Mode

JBoss 提供免費版 WildFly 和商業版 JBoss EAP ，可以讓 Java 的應用系統 war 檔執行在此平台上，若是架設正式環境則建議使用 商業版 JBoss EAP ，不然就必需要有非常高深的功力了。商業版 JBoss EAP 提供有 Standalone Mode 與 Domain Mode 兩種，若希望 Java 的 war 檔可以自動佈署在不同的主機上，使用 Domain Mode 是一個不錯的建議。在建置 JBoss EAP 的 Domain Mode 前，本人還是比較傾向先規劃好架構，這樣才知道整體的運作。下面是規劃建置圖：

• 設定 Domain Control 主機 Hostname: dc-master / IP: 192.168.2.4

Host: 192.168.2.4 裡面裝兩個角色，一個角色是 Domain Controller 用來控制 server-one、server-two 及 server-three，另一個角色是 server-one。JBoss EAP 的 ZIP 壓縮檔解開放在 d:\AppServ\jboss-eap-6.2，所以修改d:\AppServ\jboss-eap-6.2\domain\configuration\host.xml，注意：host name 的值必需是唯一值。

<host name="EAP-Domain-Master" xmlns="urn:jboss:domain:1.5">
    ......
    <domain-controller>
        <local/>
    </domain-controller>

    <servers>
        <server name="server-one" group="main-server-group"/>
    </servers>

</host>

• 建立 Domain Mode 主機間溝通用專用的帳號

在 Domain Control 主機 Host name: dc-master / ip: 192.168.2.4 建立 Domain Mode 主機間溝通用專用的帳號：domainMaster，並取得 secret key：UEBzc3cwcmQ=。

D:\AppServ\jboss-eap-6.2\bin>add-user.bat

What type of user do you wish to add?
 a) Management User (mgmt-users.properties)
 b) Application User (application-users.properties)
(a): a

Enter the details of the new user to add.
Using realm 'ManagementRealm' as discovered from the existing property files.
Username : domainMaster
Password : xxxxx
Re-enter Password : xxxxx
What groups do you want this user to belong to? (Please enter a comma separated list, or leave blank for none)[  ]:
About to add user 'domainMaster' for realm 'ManagementRealm' Is this correct yes/no? yes
Added user 'domainMaster' to file 'D:\AppServ\jboss-eap-6.2\standalone\configuration\mgmt-users.properties'
Added user 'domainMaster' to file 'D:\AppServ\jboss-eap-6.2\domain\configuration\mgmt-users.properties'
Added user 'domainMaster' with groups  to file 'D:\AppServ\jboss-eap-6.2\standalone\configuration\mgmt-groups.properties'
Added user 'domainMaster' with groups  to file 'D:\AppServ\jboss-eap-6.2\domain\configuration\mgmt-groups.properties'
Is this new user going to be used for one AS process to connect to another AS process?
e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls. yes/no? yes
To represent the user add the following to the server-identities definition <secret value="UEBzc3cwcmQ=" />
Press any key to continue . . .

• 設定 Slave 主機 Hostname: dc-slave / IP: 192.168.3.118 上的第一個 EAP 主機： EAP-instance-two

修改 D:\AppServ\jboss-eap-6.2-1\domain\configuration\host.xml，因為 EAP-instance-two & EAP-instance-three 是在同一台主機 Hostname: dc-slave / IP: 192.168.3.118 上，所以 management port 要作變動。修改 D:\AppServ\jboss-eap-6.2-1\domain\configuration\host.xml

<host name="EAP-instance-two" xmlns="urn:jboss:domain:1.5">
...
    <management>

        <security-realms>
            <security-realm name="ManagementRealm">
                <server-identities>
                    <secret value="UEBzc3cwcmQ="/>
                </server-identities>
...
        <management-interfaces>
            <native-interface security-realm="ManagementRealm">
                <socket interface="management" port="${jboss.management.native.port:9998}"/>
            </native-interface>
            <http-interface security-realm="ManagementRealm">
                <socket interface="management" port="${jboss.management.http.port:9991}"/>
            </http-interface>
        </management-interfaces>
    </management>

    <domain-controller>
        <remote host="192.168.2.4"  port="9999" security-realm="ManagementRealm" username="domainMaster" />        
    </domain-controller>

        <server name="server-two" group="main-server-group" auto-start="true">
            <socket-bindings port-offset="100"/>
        </server>

</host>

• 設定 Slave 主機 Hostname: dc-slave / IP: 192.168.3.118 上的第二個EAP主機： EAP-instance-three

因為在此 EAP Instance 上有兩個 server：server-three & server-four 所以要作 port-offset，修改 D:\AppServ\jboss-eap-6.2-1\domain\configuration\host.xml

<host name="EAP-instance-three" xmlns="urn:jboss:domain:1.5">
...
    <management>

        <security-realms>
            <security-realm name="ManagementRealm">
                <server-identities>
                    <secret value="UEBzc3cwcmQ="/>
                </server-identities>
...
        <management-interfaces>
            <native-interface security-realm="ManagementRealm">
                <socket interface="management" port="${jboss.management.native.port:9997}"/>
            </native-interface>
            <http-interface security-realm="ManagementRealm">
                <socket interface="management" port="${jboss.management.http.port:9992}"/>
            </http-interface>
        </management-interfaces>
    </management>

    <domain-controller>
        <remote host="192.168.2.4"  port="9999" security-realm="ManagementRealm" username="domainMaster" />        
    </domain-controller>

    <servers>
        <server name="server-three" group="main-server-group" auto-start="true">
            <socket-bindings port-offset="200"/>
        </server>
        <server name="server-four" group="main-server-group" auto-start="true">
            <socket-bindings socket-binding-group="ha-sockets" port-offset="300"/>
        </server>
    </servers>

</host>

• 啟動 Domain Control 主機 Hostname: dc-master / IP: 192.168.2.4

d:/>domain.bat -b YourMasterHostName -bmanagement YourMasterHostName

例: d:/>domain.bat -b dc-master -bmanagement dc-master
或: d:/>domain.bat -b 192.168.2.4  -bmanagement 192.168.2.4

• 啟動 Slave 主機 Hostname: dc-slave / IP: 192.168.3.118 上的兩個EAP主機

在 Linux 平台執行的指令

./domain.sh -Djboss.domain.master.address=YourMasterHostName -b SlaveHostName -bmanagement SlaveHostName

在 Window 平台執行的指令

D:\>AppServ\jboss-eap-6.2-1\bin\domain.bat -Djboss.domain.master.address=192.168.2.4 -b 192.168.3.118 -bmanagement 192.168.3.118
與
D:\>AppServ\jboss-eap-6.2-2\bin\domain.bat -Djboss.domain.master.address=192.168.2.4 -b 192.168.3.118 -bmanagement 192.168.3.118

• 進入管理介面 http://192.168.2.4:9990/console 查看是否有依架構執行

若都有正常運行，那麼 JBoss EAP 的 Domain Mode 代表設置正常。
