本来mysql运行得好好的,修改了一次root密码,貌似没成功,当时也没在意,mysql也没出问题。到了第二天,启动时报了这个错误“access denied for user 'root'@'localhost' using password yes”。网上解决的方法很多,试了几个都不行,下面就贴出自己实践成功后的方法,
以下内容根据论坛“http://topic.csdn.net/u/20090515/21/2b3c9a12-d8a5-4bb1-9895-6069cef5aef8.html”整理,使得解决方法有个更清晰的步骤.
1.停止Mysql的服务:c:\>sc stop mysql(net stop mysql/net start mysql)
2.首先进入windows命令行模式,本人的mysql安装在D盘,切换到mysql bin目录下。命令格式如下:cd D:/mysql/bin
然后敲下面的粗体的命令。注意你的my.ini位置。
D:/MySQL\bin>mysqld --defaults-file="D:\MySQL\\my.ini" --console --skip-grant-tables

n 5.0 and above. It is replaced by the binary log. Now starting MySQL with --log
-bin='' instead.

看到这个结果就说明MySQL已经起来了。
3.再打开一个dos窗口,同样切换到bin目录下
D:\MySQL\bin>mysql -uroot mysql 显示结果如下:
4.继续下面这个步骤,输入:
