一鍵重設mysql的root密碼的實現指令碼_DOS/BAT

重設mysql的root密碼方法有很多，本文介紹的這個是使用批處理來完成的

@echo offtitle mysql::從註冊表找到Mysql的安裝路徑寫入檔案mysql.txtreg query HKLM\SYSTEM\ControlSet001\Services\MySQL | find /I "ImagePath">C:\mysql.txtif %errorlevel% neq 0 (echo MySQL not foundpauseexit)::以”為分隔字元，截取第二段內容儲存到變數mysqlPathFOR /F tokens^=2^ delims^=^" %%i in (C:\mysql.txt) do set mysqlPath=%%idel C:\mysql.txt /f::路徑中/替換為\set mysqlPath=%mysqlPath:/=\%::刪除路徑最後一個字元（該字元不可見，可能是斷行符號換行之類的）set mysqlPath=%mysqlPath:~0,-1%:BACKTOMAIN::取得路徑最後一個字元看等不等於\set character=%mysqlPath:~-1,1%::如果最後一個字元不等於\，那麼跳轉到GETPATH刪除mysqlPath的最後一個字元if not %character% == \ goto GETPATH::進入mysql安裝路徑C:\Program Files\MySQL\MySQL Server 5.0\bincd /d "%mysqlPath%"::echo %mysqlPath%if %errorlevel% neq 0 (echo MySQL not foundpauseexit) www.jb51.net::禁用mysql服務，跳過許可權驗證修改密碼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::因為是互動式，所以從檔案讀取內容mysql <C:\config.tmptaskkill /F /IM mysqld-nt.exenet stop mysql >nulnet start mysqldel C:\config.tmp /Fpauseexit::刪除路徑最後一個字元，跳回主程式:GETPATHset mysqlPath=%mysqlPath:~0,-1%goto BACKTOMAIN如果是用wamp一鍵安裝需要改一些指令碼，主要是註冊表搜尋路徑改變，傳回值改變，服務名改變了，mysql安裝路徑變成D:\wamp\bin\mysql\mysql5.5.24\bin，少了mysqld-nt這個東西，進程裡面也沒有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
