mysql - 错误 1045 (28000) : Access denied for user 'root' @'localhost' (using password: NO)

Question

我失去了对 MySQL v. 5.6.14 的访问权限。我有访问权限，但突然我失去了它。

寻找笔记我发现了下面的网址。我做了这些步骤，但没有成功。 http://dev.mysql.com/doc/refman/5.5/en/resetting-permissions.html

C:\Program Files\MySQL\bin>mysqld

2013-11-14 19:46:01 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details)

C:\Program Files\MySQL\bin>mysql -u root mysql1

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

注意:我在 MySQL 版本中没有 mysqld_safe 或 safe_mysqld 文件

你能帮帮我吗？下面可以看到命令生成的转储文件:

C:\mysqld --init-file=C:\\mysql-init.txt

---

C:\Program Files\MySQL\bin>mysqld --init-file=C:\\mysql-init.txt --console

我遇到了同样的问题。 mysql -u root -p 对我有用。稍后它会要求您输入密码。然后你应该输入你为 mysql 设置的密码。默认密码可以是 password，如果你没有设置的话。更多信息 here .
