配置虚拟主机！！！

server.xml里面：

<Engine name="Catalina" defaultHost="localhost"> 是唯一的。

在Engine里面加一个Host（Host可以用多个）

 

<Host name="ing" debug="0" appBase="D:/webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context path="/hello" docBase="D:/webapps/hello.war" debug="0" reloadable="true"/> </Host>

以上这段代码可能平时没怎么注意，但是看见之后，用屁股想也知道是什么作用了吧，我就不解释了。

还需要改操作系统的一个dns域名解释，让系统知道ing是要访问本地主机。

 

winXP系统: //WINDOWS/system32/drivers/etc/hosts
Win2K系统:  //WINNT/system32/drivers/etc/hosts
Linux系统:  /etc/hosts
文件中增加下面内容，然后检查一下这两个域名是否解析正确。
hosts是没有后缀名的

# Copyright (c) 1993-1999 Microsoft Corp.## This is a sample HOSTS file used by Microsoft TCP/IP for Windows.## This file contains the mappings of IP addresses to host names. Each# entry should be kept on an individual line. The IP address should# be placed in the first column followed by the corresponding host name.# The IP address and the host name should be separated by at least one# space.## Additionally, comments (such as these) may be inserted on individual# lines or following the machine name denoted by a '#' symbol.## For example:## 102.54.94.97 rhino.acme.com # source server# 38.25.63.10 x.acme.com # x client host127.0.0.1 localhost127.0.0.1 ing

 

就这样完了，在浏览器中输入：http://ing/test/

注意虚拟主机名字（ing）的取名别太随意了。我在实验的时候开始取名为：www.ing.cn实验老师失败呢！！！
