::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
cd /d "%mysqlPath%"
 
::echo %mysqlPath%
 
if %errorlevel% neq 0 (
echo MySQL not found

::禁用mysql服务，跳过权限验证修改密码
taskkill /F /IM mysqld.exe
net stop mysql >nul
start /b mysqld --skip-grant-tables
ping -n 2 127.0.0.1 >nul
set /p newpwd=-^> 请输入root用户新的密码后按回车键修改:
if "%newpwd%"=="" goto reset_mydpwd
echo use mysql >c:/config.tmp
echo update user set password=password("%newpwd%") 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 <C:/config.tmp
taskkill /F /IM mysqld.exe
net stop mysql >nul
net start mysql
del C:/config.tmp /F
