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 jiangfeng3@staff.sina.com.cn 
#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" common
RewriteEngine 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/etc

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 localhost
127.0.0.1 test.t.sina.com.cn
