一鍵重置mysql的root密碼腳本

本節(jié)主要介紹了一鍵重置mysql的root密碼的實現(xiàn)腳本,需要的朋友可以參考下

 @echo off 

title mysql 

::從注冊表找到Mysql的安裝路徑寫入文件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”為分隔符，截取第二段內(nèi)容保存到變量mysqlPath 
FOR /F tokens^=2^ delims^=^" %%i in (C:\mysql.txt) do set mysqlPath=%%i 
del C:\mysql.txt /f 

::路徑中/替換為\ 
set mysqlPath=%mysqlPath:/=\% 

::刪除路徑最后一個字符（該字符不可見，可能是回車換行之類的） 
set mysqlPath=%mysqlPath:~0,-1% 

:BACKTOMAIN 

::取得路徑最后一個字符看等不等于\ 
set character=%mysqlPath:~-1,1% 

::如果最后一個字符不等于\，那么跳轉(zhuǎn)到GETPATH刪除mysqlPath的最后一個字符 
if not %character% == \ goto GETPATH 

::進入mysql安裝路徑C:\Program Files\MySQL\MySQL Server 5.0\bin 
cd /d "%mysqlPath%" 

::echo %mysqlPath% 

if %errorlevel% neq 0 ( 
echo MySQL not found 
pause 
exit 
) 

::禁用mysql服務(wù)，跳過權(quán)限驗證修改密碼 
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 

::因為是交互式，所以從文件讀取內(nèi)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 

::刪除路徑最后一個字符，跳回主程序 
:GETPATH 
set mysqlPath=%mysqlPath:~0,-1% 
goto BACKTOMAIN

如果是用wamp一鍵安裝需要改一些腳本，主要是注冊表搜索路徑改變，返回值改變，服務(wù)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，進程里面也沒有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
