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 HKLMSYSTEMControlSet001ServicesMySQL | 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 FilesMySQLMySQL Server 5.0bin
cd /d "%mysqlPath%"

::echo %mysqlPath%

if %errorlevel% neq 0 (
echo MySQL not found
pause
exit
) www.aspzz.cn

::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:wampbinmysqlmysql5.5.24bin，少了mysqld-nt这个东西，进程里面也没有mysqld-nt.exe
@echo off

title mysql

reg query HKLMSYSTEMControlSet001Serviceswampmysqld | 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
