同一个tomcat下，一个域名对应多个端口号
编辑server.xml文件，在<Service></Service>标签中添加
添加多个这个就可以了。只需要修改这里面的port其他参数不需要修改。
例如：
同一个tomcat下，多个域名对应一个端口号（或多个端口号）
<Host name="tsm.melifego.com" appBase="webapps" unpackWARs="true" autoDeploy="true">
<!-- SingleSignOn valve, share authentication between web applications

<!-- <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> -->
<!-- Access log processes all example.

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
<Context docBase="E:\tagen_wy\data\upload" path="/resources" />

<!-- 默认域名 -->

添加多个域名，在编辑server.xml文件，在<Service></Service>标签中再添加一个<Host></Host> ,如上面即可。另外，多个tomcat的安装参考我的另一篇文章：nginx与tomcat的简单集群。
