打开tomhome/conf/下的server.xml
添加以下内容：
<Host appBase="C:/aaaa" autoDeploy="true" debug="0" deployXML="true" liveDeploy="true" name="www.xxxxxxxx.com" unpackWARs="true">
<Context cachingAllowed="true" cookies="true" crossContext="true" debug="0" docBase="C:/aaa/bbb" path="" privileged="false" reloadable="true" swallowOutput="false" useNaming="true" >
</Context>
</Host>
仅仅这样还是不够的，配置后，现在输入http://localhost:8080/以及你的IP：8080是没有问题，可是要想从外网访问就必需配置你的hosts文件了。
windows服务器在：C:\WINNT\system32\drivers\etc\下，直接用记事本打开就可以了
例：
# 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 host 127.0.0.1 localhost
*.*.*.* www.***.com |
linux服务器在/etc/下,命令行下：vi hosts
例：
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost lkpor1
*.*.*.* www.***.com |
如果在Tomcat下面配置域名（如：
www.***.com）的时候，同时又不希望客户通过我们网站的IP或者域名访问到Tomcat默认的ROOT，配制方法如下：
1、打开Tomcat安装目录下的\conf\server.xml文件
2、在server.xml中将原有的<Host name=“localhost“ appBase=“webapps“ ……>修改为<Host name=“您要配置的域名“ appBase=“webapps“……>
3、在\conf\Catalina目录下建立目录“<您要配置的域名的名称>”,然后建立ROOT.xml文件，其格式和\conf\localhost目录下的ROOT.xml一致，但是内容如下：
<?xml version='1.0' encoding='utf-8'?>
<Context displayName="Welcome to 56World!" docBase="D:\workplace\inbuilding" path="">
</Context>
其中docBase中的内容就是你希望的打开您的域名（
www.***.com） 的时候映射到的目录和默认的网页（如：index.jsp）
4、启动Tomcat服务器，就可以直接敲入域名访问你要访问的地址了。
