Question

我一直在尝试重置MySQL的密码，但我找到的所有解决方案似乎都没有用。我正在使用OSX Yosemite和MAMP以及MySQL 5.6.20

我尝试通过MAMP将密码重置为pass但不起作用

$mysql -u root -p
Enter password: pass
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
$

并且这一切都不起作用

$mysql -uroot
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
$mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
$mysql -u root@localhost

Answer 1

您可以使用--skip-grant-tables选项停止mysql服务器并重新启动它。这样，在打开mysql shell时它不会查看凭据

之后，

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

停止mysql服务器，然后重新启动

Answer 2

只需在Justin的Kiang回答中添加一些细节（这对我有所帮助，谢谢！）。在我的OS X机器上：

sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server start --skip-grant-tables
mysql -u root

然后根据Justin的回答SQL代码：

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

再次重启MySQL服务器：

sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server start

根据需要调整mysql文件夹的路径。

重置mysql root pass
