server.xml引入子文件配置（tomcat虚拟主机）

在配置tomcat虚拟主机时候，如何每一个虚拟主机写成单独文件，server.xml包含这些子文件？ 如以下《OneinStack》中，添加JAVA环境虚拟主机后tomcat配置文件详情：

/usr/local/tomcat/conf/server.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE server-xml [
<!ENTITY localhost-vhost SYSTEM "file:///usr/local/tomcat/conf/vhost/localhost.xml">
<!ENTITY java.linuxeye.com-vhost SYSTEM "file:///usr/local/tomcat/conf/vhost/java.linuxeye.com.xml">
<!ENTITY demo.linuxeye.com-vhost SYSTEM "file:///usr/local/tomcat/conf/vhost/demo.linuxeye.com.xml">
]>
<Server port="8006" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener"/>
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/>
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener"/>
  <Listener className="org.apache.catalina.core.AprLifecycleListener"/>
<!--
  <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="8081" rmiServerPortPlatform="8082" />
-->
  <GlobalNamingResources>
    <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="org.apache.coyote.http11.Http11AprProtocol"
              connectionTimeout="20000"
              redirectPort="8443"
              maxThreads="1000"
              minSpareThreads="20"
              acceptCount="1000"
              debug="0"
              disableUploadTimeout="true"
              useBodyEncodingForURI="true"
              enableLookups="false"
              URIEncoding="UTF-8" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      &localhost-vhost;
      &java.linuxeye.com-vhost;
      &demo.linuxeye.com-vhost;
    </Engine>
  </Service>
</Server>
注：在<server>元素前添加如下格式：

<!DOCTYPE server-xml [
  <!ENTITY localhost-vhost SYSTEM "file:///usr/local/tomcat/conf/vhost/localhost.xml">
]>
并在<Engine>...</Engine]引用它（localhost-vhost，注：不能以数字开头）即可。

下面是每个单独虚拟主机文件：/usr/local/tomcat/conf/vhost/localhost.xml

<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
  <Context path="" docBase="/data/wwwroot/default" debug="0" reloadable="true" crossContext="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" />
/usr/local/tomcat/conf/vhost/demo.linuxeye.com.xml

<Host name="demo.linuxeye.com" appBase="webapps" unpackWARs="true" autoDeploy="true">
  <Context path="" docBase="/data/wwwroot/demo.linuxeye.com" debug="0" reloadable="true" crossContext="true"/>
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
         prefix="demo.linuxeye.com_access_log." suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />
/usr/local/tomcat/conf/vhost/java.linuxeye.com.xml

<Host name="java.linuxeye.com" appBase="webapps" unpackWARs="true" autoDeploy="true"> <Alias>java1.linuxeye.com</Alias>
  <Context path="" docBase="/data/wwwroot/java.linuxeye.com" debug="0" reloadable="true" crossContext="true"/>
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
         prefix="java.linuxeye.com_access_log." suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>
