我确信我有正确的密码。当我重新启动电脑时，我甚至无法从命令提示符连接到MYSQLn

错误是：

error 1045（28000）：拒绝用户'root'@'localhost'的访问（使用密码：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上运行）
但这是徒劳的
init.txt的内容是：

UPDATE mysql.user SET Password=PASSWORD('123') WHERE User='root'; FLUSH PRIVILEGES;
日志输出为：

更新：

ping也可以很好地工作
很明显，您正在遵循MySQL手册中的章节，这是一个好主意。但您的日志表明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，该手册仍然没有提到用户帐户控制（UAC），这是WindowsVista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
我不知道在Windows 8中是什么样子，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“以管理员身份运行”：

这称为提升的命令提示符。

您描述了两个不同的问题：1）您似乎不知道您的根密码是什么2）您无法从命令行启动MySQL服务器，可能是因为您的命令行没有提升没有我有正确的根用户密码。我可以从服务启动MySQL服务器。但我可以访问itI我也面临同样的问题，你可以在这里找到答案[1][1]：
