conf/server.xml
移除注释内容后，类似内容如下：
<Server>
……
……
……
<Service name="Catalina">
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true"

</Service>
</Server>
多个虚拟主机的配置，即增加 <service> 或 <host> 标签段。
一、端口方式：<Service>
在</Service>与</Server>之间增加
</Host>
</Engine>
</Service> <!-- 虚拟主机：端口方式 须修改三个地方： Service name / Connetor port / Host appBase
appBase可为相对路径，也可为绝对路径
--> <Service name="Catalina2">
<Connector port="6038" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="6444" />
<Connector port="6010" protocol="AJP/1.3" redirectPort="6444" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
<Host name="localhost" appBase="webapps2"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
</Engine>
</Service>
</Server>
http://localhost:8080/
http://locathost:6037/
二、域名方式：<Host>
在</Host>与</Engine>之间增加
</Host>
<!--虚拟主机：域名方式，需修改 Host name/appBase
-->
<Host name="a.b.c" appBase="webapps2"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
</Engine>
</Service>
</Server>
http://locathost:8080/
http://a.b.c:8080/
