连接到Mysql失败-错误1045 - windows 8

Question

我确信我有正确的密码。当我重新启动我的PC时，即使从命令提示符，我也无法连接到MYSQLn。

错误是：ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

这可能是WIN 8的问题吗？

更新：

甚至我也使用过这个命令行(，它在XP上工作)

mysqld --defaults-file="C:/Program Files/MySQL/MySQL Server 5.6/my-default.ini" --init-file="C:\config/init.txt"

但徒劳无功

init.txt的内容如下：

UPDATE mysql.user SET Password=PASSWORD('123') WHERE User='root';
FLUSH PRIVILEGES;

日志输出是：

ted. Please use --explicit_defaults_for_timestamp server option (see documentati
on for more details).

平定也很好

显然，您正在遵循如何重置根密码手册中的MySQL章节，这是一个很好的主意。但是您的日志显示，MySQL无法编写自己的文件：

InnoDB:系统表空间必须是可写的！

问题是手册中仍然没有提到用户帐户控制(UAC)，这是Windows在2007年左右引入的一种安全机制。即使您的用户是管理员，也需要在需要时显式授予管理权限。

我不知道Windows 8中的情况，但在Windows 7中，您需要在“开始”菜单中找到“命令提示符”图标，右键单击它并选择“”：

这称为提升的命令提示符。
