将CNAME转发给Tomcat

我有一个带有DIY盒带的OpenShift实例，在这里我个人配置了ApacheTomcat。这是我的

server.xml

：

<?xml version='1.0' encoding='utf-8'?>
<Server port="15005" shutdown="SHUTDOWN" address="OPENSHIFT_DEV_IP">

 <Listener className="org.apache.catalina.security.SecurityListener" />
 <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
 <Listener className="org.apache.catalina.core.JasperListener" />
 <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
 <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
 <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

 <GlobalNamingResources>

            username="####"
            password="####"
            maxActive="20"
            maxIdle="5"
            maxWait="-1"
            description="SSU TT database"
            />  

<Resource name="UserDatabase" auth="Container"
          type="org.apache.catalina.UserDatabase"
          description="User database that can be updated and saved"
          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
          pathname="conf/tomcat-users.xml" />
   </GlobalNamingResources>

 <Service name="Catalina">


<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           address="OPENSHIFT_DEV_IP"
           redirectPort="15443" />
<Connector port="15009" protocol="AJP/1.3" redirectPort="8443" address="OPENSHIFT_DEV_IP"/>


<Engine name="Catalina" defaultHost="OPENSHIFT_DEV_IP">

  <Realm className="org.apache.catalina.realm.LockOutRealm">
    <!-- This Realm uses the UserDatabase configured in the global JNDI
         resources under the key "UserDatabase".  Any edits
         that are performed against this UserDatabase are immediately
         available for use by the Realm.  -->
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
           resourceName="UserDatabase"/>
  </Realm>

  <Host name="backend-ssutt.rhcloud.com"  appBase="webapps"
        unpackWARs="true" autoDeploy="true">

    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
           prefix="localhost_access_log." suffix=".txt"
           pattern="%h %l %u %t &quot;%r&quot; %s %b" />

  </Host>

 </Engine>
 </Service>
</Server>

我可以通过

后端ssutt.rhcloud.com

访问它。没关系。奇怪的是，我不能通过其他地址访问它，比如

api.ssutt.org

，但是我添加了别名和DNS CNAME记录

奇怪的是，它正在使用默认的Tomcat7/EWS盒式磁带。如何将Tomcat或我的DNS记录配置为可通过其他地址访问。

通过向Tomcat配置添加

别名解决了此问题
