将CNAME转发给Tomcat

Question

我有一个使用DIY盒式磁带的OpenShift实例，我亲自配置了Apache Tomcat。这里是我的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> 
<Resource name="jdbc_ttDS" auth="Container" 
     type="javax.sql.DataSource" 
      driverClassName="org.h2.Driver" 
      url="jdbc:h2:ssutt;INIT=RUNSCRIPT FROM './initTT.sql'" 

      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backend-ssutt.rhcloud.com访问它。没关系。奇怪的是，我不能通过其他地址如api.ssutt.org访问它，但我添加了实例和DNS CNAME记录的别名。

奇怪的是，它正在使用默认的Tomcat 7/EWS盒式磁带。我如何配置Tomcat或我的DNS记录，以便通过其他地址访问。

该问题已通过将Alias添加到Tomcat配置中解决。 Official documentation
