方法一:在my.ini的[mysqld]字段加入:
skip-grant-tables
重啟mysql服務,這時的mysql不需要密碼即可登錄數據庫然后進入mysql
mysql>use mysql;mysql>更新 user set password=password('新密碼') WHERE User='root';
mysql>flush privileges;運行之后最后去掉my.ini中的skip-grant-tables,重啟mysqld即可。方法二:不使用修改my.ini重啟服務的方法,通過非服務方式加skip-grant-tables運行mysql來修改mysql密碼停止mysql服務打開命令行窗口,在bin目錄下使用mysqld-nt.exe啟動,即在命令行窗口執行: mysqld-nt --skip-grant-tables然后另外打開一個命令行窗口,登錄mysql,此時無需輸入mysql密碼即可進入。按以上方法修改好密碼后,關閉命令行運行mysql的那個窗口,此時即關閉了mysql,如果發現mysql仍在運行的話可以結束掉對應進程來關閉。啟動mysql服務
