一键重置mysql的root密码的实现脚本

重置MysqL的root密码方法有很多，本文介绍的这个是使用批处理来完成的

@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
) www.jb51.net

::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 <C:\config.tmp
taskkill /F /IM MysqLd-nt.exe
net stop 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
