 @echo off 

title mysql 

::从注册表找到Mysql的安装路径写入文件mysql.txt 
reg query HKLM\SYSTEM\ControlSet001\Services\MySQL | find /I "ImagePath">C:\mysql.txt 
if %errorlevel% neq 0 ( 
echo MySQL not found 
pause 
exit 
) 

::以”为分隔符,截取第二段内容保存到变量mysqlPath 
FOR /F tokens^=2^ delims^=^" %%i in (C:\mysql.txt) do set mysqlPath=%%i 
del C:\mysql.txt /f 

::路径中/替换为\ 
set mysqlPath=%mysqlPath:/=\% 

::删除路径最后一个字符(该字符不可见,可能是回车换行之类的) 
set mysqlPath=%mysqlPath:~0,-1% 

:BACKTOMAIN 

::取得路径最后一个字符看等不等于\ 
set character=%mysqlPath:~-1,1% 

::如果最后一个字符不等于\,那么跳转到GETPATH删除mysqlPath的最后一个字符 
if not %character% == \ goto GETPATH 

::进入mysql安装路径C:\Program Files\MySQL\MySQL Server 5.0\bin 
cd /d "%mysqlPath%" 

::echo %mysqlPath% 

if %errorlevel% neq 0 ( 
echo MySQL not found 
pause 
exit 
) 

::禁用mysql服务,跳过权限验证修改密码 
taskkill /F /IM mysqld-nt.exe 
net stop mysql >nul 
start /b mysqld-nt --skip-grant-tables 
ping -n 2 127.0.0.1 >nul 
echo use mysql >c:\config.tmp 
echo update user set password=password("") where user="root";>>C:\config.tmp 
echo flush privileges; >>C:\config.tmp 
echo exit >>C:\config.tmp 

::因为是交互式,所以从文件读取内容 
mysql nul 
net start mysql 
del C:\config.tmp /F 
pause 
exit 

::删除路径最后一个字符,跳回主程序 
:GETPATH 
set mysqlPath=%mysqlPath:~0,-1% 
goto BACKTOMAIN

如果是用wamp一键安装需要改一些脚本,主要是注册表搜索路径改变,返回值改变,服务名改变了,mysql安装路径变成D:\wamp\bin\mysql\mysql5.5.24\bin,少了mysqld-nt这个东西,进程里面也没有mysqld-nt.exe

@echo off 

title mysql 

reg query HKLM\SYSTEM\ControlSet001\Services\wampmysqld | find /I "ImagePath">C:\mysql.txt 

if %errorlevel% neq 0 ( 
echo MySQL not found 
pause 
exit 
) 

FOR /F "tokens=3 delims= " %%i in (C:\mysql.txt) do set mysqlPath=%%i 
del C:\mysql.txt /f 
set mysqlPath=%mysqlPath:/=\% 
set mysqlPath=%mysqlPath:~0,-1% 

:BACKTOMAIN 
set character=%mysqlPath:~-1,1% 
if not %character% == \ goto GETPATH 
cd /d "%mysqlPath%" 

::echo %mysqlPath% 

if %errorlevel% neq 0 ( 
echo MySQL not found 
pause 
exit 
) 

taskkill /F /IM mysqld.exe 
net stop wampmysqld >nul 
start /b mysqld -nt --skip-grant-tables 
ping -n 2 127.0.0.1 >nul 
echo use mysql >c:\config.tmp 
echo update user set password=password("") where user="root";>>C:\config.tmp 
echo flush privileges; >>C:\config.tmp 
echo exit >>C:\config.tmp 

mysql nul 
net start wampmysqld 
del C:\config.tmp /F 

pause 
exit 

:GETPATH 
set mysqlPath=%mysqlPath:~0,-1% 
goto BACKTOMAIN
