在一个tomcat下，一域名对应多端口，一端口对应多域名;在多个tomcat下，不同域名对应不同端口的配置

一.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。

eg.

二。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
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->
        <!-- Access log processes all example.

             Note: The pattern used is equivalent to using pattern="common" -->
        <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" />
<Context docBase="E:\tagen_wy\data\upload" path="/resources" />
         <!--
        <Context docBase="E:\tagen_wy\data\property-management" path="/property-management" />
  <Context docBase="E:\tagen_wy\data\property-wechat-service" path="/property-wechat-service"  />
<Context docBase="E:\tagen_wy\data\property-wechat-wap" path="/property-wechat-wap" />
         -->
        <Context docBase="E:\tagen_wy\data\st-imgs" path="/st-imgs"  /> 
      </Host>


 <Host     name="wechat.tagen-pm.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->
        <!-- Access log processes all example.

             Note: The pattern used is equivalent to using pattern="common" -->
        <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" />
<Context docBase="E:\tagen_wy\data\upload" path="/resources" />
         <!--
        <Context docBase="E:\tagen_wy\data\property-management" path="/property-management" />
  <Context docBase="E:\tagen_wy\data\property-wechat-service" path="/property-wechat-service"  />
<Context docBase="E:\tagen_wy\data\property-wechat-wap" path="/property-wechat-wap" />
         -->
        <Context docBase="E:\tagen_wy\data\st-imgs" path="/st-imgs"  />
      </Host>

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，
