MYSQL 访问被拒绝用户 'root' @'localhost'

Question

我做了以下步骤在 Ubuntu 中使用 MySQL:

sudo aptitude install php5-mysql mysql-server
sudo service mysql stop
sudo mysqld_safe --skip-grant-tables &
sudo mysql -u root mysql

修改root密码:

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

修改/etc/mysql/my.cnf:

[client]
user=root
password=SecurePassword
[mysqld]
...
default-time-zone = '+0:00'

然后:

sudo service mysql start
mysql -u root
mysql> SHOW GRANTS FOR root@localhost
+--------------------------------------------------------------------------------------------------+
 | Grants for root@localhost | 
+--------------------------------------------------------------------------------------------------+
 | GRANT USAGE ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '[here is the Securepassword]' |
 +-------------------------------------------------------------------------------------------------+
 1 row in set (0.00 sec) 

mysql>
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost'  WITH GRANT OPTION;

我收到一个错误:

Access denied for user 'root'@'localhost' (using password: YES)

Answer 1

你所做的绝对正确，但我想它不起作用是因为一个小原因。

当你要授予这样的权限时，你应该使用 identified by password:

mysql> GRANT ALL PRIVILEGES ONE `*`.`*` TO 'root'@'localhost' IDENTIFIED BY PASSWORD
'*A4B6157319038724E3560894F7F932C8886EBFCF' WITH GRANT OPTION;
