用户'root'@'localhost'的MYSQL访问被拒绝 [英] MYSQL Access denied for user 'root'@'localhost'

问题描述

我执行了以下步骤以在Ubuntu中使用MySQL:

I did the following steps to use MySQL in Ubuntu:

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

更改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:

Modify /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:

拒绝用户'root'@'localhost'的访问(使用密码:是)

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

推荐答案

您所做的工作绝对正确，但是我认为它不起作用的原因有一个.

It was absolutely correct what you did, but I guess it's not working for one small reason.

要授予这样的特权时，应使用identified by password:

You should use identified by password when you are going to grant privileges like this:

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