JBoss4 应用服务器Web开发人员参考手册(7)：设置虚拟主机

虚拟主机允许按照运行JBoss机器的不同DNS名称对Web应用进行分组。例如，Example 7.1, “A virtual host configuration.”给出的server.xml配置文件，除了定义一个缺省虚拟主机vhost1.mydot.com外，还定义了第二个虚拟主机vhost2.mydot.com及其别名www.mydot.com.

Example 7.1. A virtual host configuration.

<Server>

   <Service name="jboss.web"

      className="org.jboss.web.tomcat.tc5.StandardService">

      <!-- A HTTP/1.1 Connector on port 8080 -->

      <Connector port="8080" address="${jboss.bind.address}"

                 maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

                 enableLookups="false" redirectPort="8443" acceptCount="100"

                 connectionTimeout="20000" disableUploadTimeout="true"/>

      <Engine name="jboss.web" defaultHost="vhost1">

         <Realm className="org.jboss.web.tomcat.security.JBossSecurityMgrRealm"

                certificatePrincipal="org.jboss.security.auth.certs.SubjectDNMapping"

            />

         <Logger className="org.jboss.web.tomcat.Log4jLogger"

                 verbosityLevel="WARNING"

                 category="org.jboss.web.localhost.Engine"/>

            <Host name="vhost1" autoDeploy="false"

                  deployOnStartup="false" deployXML="false">

                <Alias>vhost1.mydot.com</Alias>

                <Valve className="org.apache.catalina.valves.AccessLogValve"

                       prefix="vhost1" suffix=".log" pattern="common"

                       directory="${jboss.server.home.dir}/log"/>

                <DefaultContext cookies="true" crossContext="true" override="true"/>

            </Host>   

            <Host name="vhost2" autoDeploy="false" 

                  deployOnStartup="false" deployXML="false">

                <Alias>vhost2.mydot.com</Alias>

                <Alias>www.mydot.com</Alias>  

                <Valve className="org.apache.catalina.valves.AccessLogValve"

                       prefix="vhost2" suffix=".log" pattern="common" 

                       directory="${jboss.server.home.dir}/log"/>

                <DefaultContext cookies="true" crossContext="true" override="true"/>

            </Host>

      </Engine>

   </Service>

</Server>

在缺省情况下，部署的WAR包将会绑定到Engine元素defaultHost属性匹配的虚拟主机. 为了将WAR包部署到指定的虚拟主机上，必须在jboss-web.xml描述文件中指定合适的virtual-host. 下面的 jboss-web.xml 描述文件演示了怎样将一个WAR包部署到特定的虚拟主机 www.mydot.com上. 值得注意的是，在配置文件中既可以使用虚拟主机名，也可以使用真实的主机名.

<jboss-web>

    <context-root>/</context-root>

    <virtual-host>www.mydot.com</virtual-host>

</jboss-web>
