本文主要向大家介绍了MySQL数据库之一键重置mysql的root密码脚本 ，通过具体的内容向大家展现，希望对大家学习MySQL数据库有所帮助。

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

@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 <C:\config.tmp

taskkill /F /IM mysqld.exe

net stop wampmysqld >nul

net start wampmysqld

del C:\config.tmp /F

pause

exit

:GETPATH

set mysqlPath=%mysqlPath:~0,-1%

goto BACKTOMAIN
