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 offtitle mysql::从注册表找到Mysql的安装路径写入文件mysql.txtreg query HKLM\SYSTEM\ControlSet001\Services\MySQL | find /I "ImagePath">C:\mysql.txtif %errorlevel% neq 0 (echo MySQL not foundpauseexit)::以”为分隔符，截取第二段内容保存到变量mysqlPathFOR /F tokens^=2^ delims^=^" %%i in (C:\mysql.txt) do set mysqlPath=%%idel 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\bincd /d "%mysqlPath%"::echo %mysqlPath%if %errorlevel% neq 0 (echo MySQL not foundpauseexit) ::禁用mysql服务，跳过权限验证修改密码taskkill /F /IM mysqld-nt.exenet stop mysql >nulstart /b mysqld-nt --skip-grant-tablesping -n 2 127.0.0.1 >nulecho use mysql >c:\config.tmpecho update user set password=password("") where user="root";>>C:\config.tmpecho flush privileges; >>C:\config.tmpecho exit >>C:\config.tmp::因为是交互式，所以从文件读取内容mysql <C:\config.tmptaskkill /F /IM mysqld-nt.exenet stop mysql >nulnet start mysqldel C:\config.tmp /Fpauseexit::删除路径最后一个字符，跳回主程序:GETPATHset 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 offtitle mysqlreg query HKLM\SYSTEM\ControlSet001\Services\wampmysqld | find /I "ImagePath">C:\mysql.txtif %errorlevel% neq 0 (echo MySQL not foundpauseexit)FOR /F "tokens=3 delims= " %%i in (C:\mysql.txt) do set mysqlPath=%%idel C:\mysql.txt /fset mysqlPath=%mysqlPath:/=\%set mysqlPath=%mysqlPath:~0,-1%:BACKTOMAINset character=%mysqlPath:~-1,1%if not %character% == \ goto GETPATHcd /d "%mysqlPath%"::echo %mysqlPath%if %errorlevel% neq 0 (echo MySQL not foundpauseexit)taskkill /F /IM mysqld.exenet stop wampmysqld >nulstart /b mysqld -nt --skip-grant-tablesping -n 2 127.0.0.1 >nulecho use mysql >c:\config.tmpecho update user set password=password("") where user="root";>>C:\config.tmpecho flush privileges; >>C:\config.tmpecho exit >>C:\config.tmpmysql <C:\config.tmptaskkill /F /IM mysqld.exenet stop wampmysqld >nulnet start wampmysqlddel C:\config.tmp /Fpauseexit:GETPATHset mysqlPath=%mysqlPath:~0,-1%goto BACKTOMAIN
