MySQL 访问被拒绝错误

Question

我正在尝试在 Mac OS 10.8 上安装 mySQL 并设置用户帐户。注意在终端窗口中使用命令行时，我是一个绝对的初学者。

我使用这些说明来安装: http://www.macminivault.com/mysql-mountain-lion/

我在这里为所有用户设置了自己的密码:

 GRANT ALL ON *.* TO 'root'@'localhost' IDENTIFIED BY 'mypass' WITH GRANT OPTION;
quit

每次我尝试在命令行上以 root 用户身份执行 mySQL 时，我都会得到以下信息:

Ciarans-MacBook-Pro:~ callanmooneys$ mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

我在网上阅读并尝试了各种方法，包括尝试更改密码:

mysqladmin -u root -pyourcurrentmysqlrootpassword password yournewmysqlrootpassword,
it returns -> 
    -> USE mysql
    -> 

如果我只是输入“mysql”并启动 mySQL 监视器，然后尝试创建一个用户帐户:

mysql> USE mysql
ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mysql'
mysql> 

还尝试了论坛上的答案:access is denied for user 'root'@localhost mysql error 1045返回'root@127.0.0.1 命令未找到

和MySQL - ERROR 1045 - Access denied :

Ciarans-MacBook-Pro:~ callanmooneys$ mysqld_safe --skip-grant-tables
131105 21:44:41 mysqld_safe Logging to '/usr/local/mysql/data/Ciarans-MacBook-Pro.local.err'.

感谢反馈。

有点令人困惑，但删除了 mySQL 和所有相关文件，重新安装，设置 root 密码，登录为mysql -u root -p(密码)而且效果很好。

网上有很多资源可能会令人困惑，对于遇到类似问题的任何人，我建议使用这里的官方网站:
