Windows 7 旗舰版真是好，可惜的是不知道为什么近来变慢了，特别是浏览网页时，系统老是卡卡的，真难受。万不得已只好重装了系统，重装了Apache 2.2.17, PHP 5.3.6，安装包文件名如下： 

  httpd-2.2.17-win32-x86-openssl-0.9.8o.msi
  php-5.3.6-Win32-VC9-x86.msi

注意，PHP 5.3.5.6和Apache 2.2.15不相匹配，刚开始下载了个Apache 2.2.14来安装，结果爆出错误，浪费了半个小时时间来找错误，NND。 

错误应用程序名称: httpd.exe，版本: 2.2.15.0，时间戳: 0x4b8fed95
错误模块名称: php5ts.dll，版本: 5.3.6.0，时间戳: 0x4d81e545

我的MySQL 不用重新安装，因为之前建立了很多数据库，担心重装丢失数据，于是通过下面的命令来启动mysqld： 

  D:\MySQL51\bin\mysqld" --defaults-file="D:\MySQL51\my.ini"

Apache 虚拟主机（Virtual Host）配置实例： 

  # apache/conf/extra/httpd-vhosts.conf
  
     DocumentRoot "I:/webroot/toy"
     ServerName toy.local

     # This should be omitted in the production environment
     SetEnv APPLICATION_ENV development

     
         Options Indexes MultiViews FollowSymLinks
         AllowOverride All
         Order allow,deny
         Allow from all

同时，不要忘记在apche/conf/httd.conf中加载httpd-vhosts.conf文件： 

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

下面的是注册表中的MySQL Service信息：
