Apache 的虚拟主机就是在一台服务器上运行多个网站，每个虚拟主机都可以绑定独立的域名，为这些域名可以指定单独的目录，访问这些域名的时候，Apache 会打开对应目录里面的东西。配置 Apache 的虚拟主机，只需要去修改 Apache 的配置文件。虚拟主机的英文是 virtual host，所以，你的 Apache 配置虚拟主机的文件可能是 httpd.conf ，也可能是跟 virtual host 这个名字相关的文件，比如 vhost.conf ，具体要使用哪一个配置文件，你需要自己去判断。
新浪微博虚拟机开发配置步骤及介绍。
1、由于后面虚拟机中需要用到Rewrite所以先编辑Apache的conf目录下的httpd.conf文件。（可根据实际需要操作）
添加mod_rewrite.so模块支持。去掉下列行中前面的#号。
LoadModule rewrite_module modules/mod_rewrite.so
2、配置apache支持虚拟机。这一步很重要。
复制代码 代码如下:
# Virtual hosts
#Include conf/extra/httpd-vhosts.conf
找到 上面相关文本，去掉#Include conf/extra/httpd-vhosts.conf前的#。
复制代码 代码如下:
# Virtual hosts
Include conf/extra/httpd-vhosts.conf
保存退出。
3、编辑conf目录下extra文件夹下的httpd-vhosts.conf。
去掉实例配置，添加新有配置。以新浪微博为例，配置文件如下：
## Virtual Hosts## If you want to maintain multiple domains/hostnames on your# machine you can setup VirtualHost containers for them. Most configurations# use only name-based virtual hosts so the server doesn't need to worry about# IP addresses. This is indicated by the asterisks in the directives below.## Please see the documentation at# <URL:http://httpd.apache.org/docs/2.2/vhosts/># for further details before you try to setup virtual hosts.## You may use the command line option '-S' to verify your virtual host# configuration.## Use name-based virtual hosting.#NameVirtualHost *:80## VirtualHost example:# Almost any Apache directive may go into a VirtualHost container.# The first VirtualHost section is used for all requests that do not# match a ServerName or ServerAlias in any <VirtualHost> block.#<VirtualHost *:80>#管理员邮箱ServerAdmin [email protected] #项目根目录 DocumentRoot "D:/htdocs/frame_export" #域名 ServerName test.t.sina.com.cn #别名 ServerAlias test.t.sina.com.cn#错误日志路径ErrorLog "logs/test.t.sins.com.cn-error.log"CustomLog "logs/test.t.sins.com.cn-access.log" commonRewriteEngine on#重写规则，可根据实际需要添加RewriteRule ^/(.*)$ /apps/index.php [L]</VirtualHost>
4、编辑本地host文件，以windows为例
进入C:/Windows/System32/drivers/etchttp://www.bbqmw.net/宝宝起名网
记事本打开hosts文件
最后添加
127.0.0.1 localhost
127.0.0.1 test.t.sina.com.cn
例子：
# Copyright (c) 1993-2009 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# localhost name resolution is handled within DNS itself.127.0.0.1 localhost# ::1 localhost127.0.0.1 test.t.sina.com.cn
