假设apache和mysql都安装在非系统盘上，重装windows，apache、mysql当然都不能启动了。不甘心傻乎乎的用安装文件重新安装，开源软件一般不使用windows自己的COM等组件，安装不用做复杂的注册表操作，只要将它们的主程序注册为windows的服务就可以了，windows的sc命令可以帮助我们完成这个工作，格式是这样的:
sc create apache binPath="D:\apache2\bin\httpd.exe"
把D:\apache2\bin\httpd.exe注册为名为apache的服务。不过呢，apache和mysql自身就有注册成windows服务的功能，嘿嘿！
D:\Apache2\bin>httpd /?
Usage: httpd [-D name] [-d directory] [-f file]
[-C "directive"] [-c "directive"]
[-w] [-k start|restart|stop|shutdown]
[-k install|config|uninstall] [-n service_name]
[-v] [-V] [-h] [-l] [-L] [-t] [-S]
Options:
-D name : define a name for use in <IfDefine name> directives
-d directory : specify an alternate initial ServerRoot
-f file : specify an alternate ServerConfigFile
-C "directive" : process directive before reading config files
-c "directive" : process directive after reading config files
-n name : set service name and use its ServerConfigFile
-k start : tell Apache to start
-k restart : tell running Apache to do a graceful restart
-k stop|shutdown : tell running Apache to shutdown
-k install : install an Apache service
-k config : change startup Options of an Apache service
-k uninstall : uninstall an Apache service
-w : hold open the console window on error
-e level : show startup errors of level (see LogLevel)
-E file : log startup errors to file
-v : show version number
-V : show compile settings
-h : list available command line options (this page)
-l : list compiled in modules
-L : list available configuration directives
-t -D DUMP_VHOSTS : show parsed settings (currently only vhost settings)
-S : a synonym for -t -D DUMP_VHOSTS
-t -D DUMP_MODULES : show all loaded modules
-M : a synonym for -t -D DUMP_MODULES
-t : run syntax check for config files
D:\Apache2\bin>
根据帮助信息，执行
D:\Apache2\bin\httpd.exe -k install
apache就注册成为windows的服务了，用
D:\Apache2\bin\net start apache2.2
启动它。配合httpd.conf中的PHPIniDir "D:/php"指令php也可以继续使用
照例,MySQL的是
D:\MySQL\bin\mysqld-nt.ext --install MySQL --defaults-extra-file=D:\srv\mysql\my.ini
D:\MySQL\bin\net start mysql
