在網(wǎng)上找了半天也沒找到相關(guān)的資料,都說的太含糊.
本人對(duì)tomcat下配置 一ip對(duì)多域名的方法具體例如以下,按以下配置一定能成功,經(jīng)過測(cè)試了.

      <Host name="localhost" debug="0" appBase="D://Tomcat 5.0//webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
       <Alias>localhost.com</Alias> 
       <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs"  prefix="localhost_log." suffix=".txt"
            timestamp="true"/>
        <Context path="" docBase="D://Tomcat 5.0//webapps//gg"  reloadable="true" caseSensitive="false" debug="0"></Context>
</Host>
<Host name="one.localhost" debug="0" appBase="D://Tomcat 5.0//webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
       <Alias>one.localhost.com</Alias> 
       <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs"  prefix="localhost_log." suffix=".txt"
            timestamp="true"/>
       <Context path="" docBase="D://Tomcat 5.0//webapps//kk//a"  reloadable="true" caseSensitive="false" debug="0"></Context>
</Host>
<Host name="two.localhost" debug="0" appBase="D://Tomcat 5.0//webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
       <Alias>two.localhost.com</Alias> 
       <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs"  prefix="localhost_log." suffix=".txt"
            timestamp="true"/>
        <Context path="" docBase="D://Tomcat 5.0//webapps//kk//b"  reloadable="true" caseSensitive="false" debug="0"></Context>
</Host>
    

因無域名解析server,所以在hosts上配,來模擬dns解析.

10.1.1.241? localhost?????????? 指向gg目錄
10.1.1.241? localhost.com?????? 指向gg目錄
10.1.1.241? one.localhost?????? 指向a目錄
10.1.1.241? one.localhost.com?? 指向a目錄
10.1.1.241? two.localhost?????? 指向b目錄
10.1.1.241? two.localhost.com?? 指向b目錄

經(jīng)過多方面嘗試,最終在tomcat下配置成功了.

?

改動(dòng)默認(rèn)的應(yīng)用時(shí)：改defaulthost,并將context的path置為空。

?

?

配置多個(gè)應(yīng)用時(shí)：

如： http://localhost:8080/

???????? http://localhost:8080/first

???????? http://localhost:8080/second

相應(yīng)的配置例如以下：

      <Host name="localhost" debug="0" appBase="D://Tomcat 5.0//webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">
       <Alias>localhost.com</Alias> 
       <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs"  prefix="localhost_log." suffix=".txt"
            timestamp="true"/>
        <Context path="" docBase="D://Tomcat 5.0//webapps//Root"  reloadable="true" caseSensitive="false" debug="0"></Context>
        <Context path="/first" docBase="D://Tomcat 5.0//webapps//first"  reloadable="true" caseSensitive="false" debug="0"></Context>
        <Context path="/second" docBase="D://Tomcat 5.0//webapps//second"  reloadable="true" caseSensitive="false" debug="0"></Context>
</Host>
