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
@echooff
titlemysql
::从注册表找到Mysql的安装路径写入文件mysql.txt
regqueryHKLM\SYSTEM\ControlSet001\Services\MySQL|find/I"ImagePath">C:\mysql.txt
if%errorlevel%neq0(
echoMySQLnotfound
pause
exit
)
::以”为分隔符，截取第二段内容保存到变量mysqlPath
FOR/Ftokens^=2^delims^=^"%%iin(C:\mysql.txt)dosetmysqlPath=%%i
delC:\mysql.txt/f
::路径中/替换为\
setmysqlPath=%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）
setmysqlPath=%mysqlPath:~0,-1%
:BACKTOMAIN
::取得路径最后一个字符看等不等于\
setcharacter=%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
ifnot%character%==\gotoGETPATH
::进入mysql安装路径C:\ProgramFiles\MySQL\MySQLServer5.0\bin
cd/d"%mysqlPath%"
::echo%mysqlPath%
if%errorlevel%neq0(
echoMySQLnotfound
pause
exit
)www.nhooo.com
::禁用mysql服务，跳过权限验证修改密码
taskkill/F/IMmysqld-nt.exe
netstopmysql>nul
start/bmysqld-nt--skip-grant-tables
ping-n2127.0.0.1>nul
echousemysql>c:\config.tmp
echoupdateusersetpassword=password("")whereuser="root";>>C:\config.tmp
echoflushprivileges;>>C:\config.tmp
echoexit>>C:\config.tmp
::因为是交互式，所以从文件读取内容
mysql<C:\config.tmp
taskkill/F/IMmysqld-nt.exe
netstopmysql>nul
netstartmysql
delC:\config.tmp/F
pause
exit
::删除路径最后一个字符，跳回主程序
:GETPATH
setmysqlPath=%mysqlPath:~0,-1%
gotoBACKTOMAIN
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
