错误 1044 (42000)：用户访问被拒绝

Question

我在 MySQL 中创建了一个带有密码的新用户。

mysql> GRANT ALL PRIVILEGES ON simple_cms_development.*
    -> TO 'simple_cms'@'localhost'
    -> IDENTIFIED BY 'xxxxxxx';
Query OK, 0 rows affected (0.04 sec)

我检查了它是否已创建：

mysql> SHOW GRANTS FOR 'simple_cms'@'localhost';
+-------------------------------------------------------------------------------------------------------------------+
| Grants for simple_cms@localhost                                                                                   |
+-------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'simple_cms'@'localhost' IDENTIFIED BY PASSWORD '*CA931C969BFB20B345B153F9AE0B3EBC543B48EF' |
| GRANT ALL PRIVILEGES ON `simple_cms_development`.* TO 'simple_cms'@'localhost'                                    |
+-------------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

我尝试以该用户身份登录并收到 1044 错误：

 Macintosh-2:simple_cms kmcrayton7$ mysql -u simple_cms -p simple_csm_development;
    Enter password: 
    ERROR 1044 (42000): Access denied for user 'simple_cms'@'localhost' to database 'simple_csm_development'

按照答案#1 和 #6 中的步骤进行操作，结果如下：

mysql> select user,host,password from mysql.user;
+------------+-----------+-------------------------------------------+
| user       | host      | password                                  |
+------------+-----------+-------------------------------------------+
| root       | localhost | *986BD1453A6B2F3CCF85DC695B981EE516B7613D |
| root       | macintosh | *986BD1453A6B2F3CCF85DC695B981EE516B7613D |

|            | macintosh |                                           |
| simple_csm | localhost | *CA931C969BFB20B345B153F9AE0B3EBC543B48EF |
| simple_cms | localhost | *CA931C969BFB20B345B153F9AE0B3EBC543B48EF |
+------------+-----------+-------------------------------------------+
8 rows in set (0.04 sec)

mysql> exit
Bye
Macintosh-2:simple_cms kmcrayton7$ mysql -u simple_cms -p simple_csm_development;
Enter password: 
ERROR 1044 (42000): Access denied for user 'simple_cms'@'localhost' to database 'simple_csm_development'

我不知道我在哪里犯了我的错误

我试图遵循以下建议，但现在我似乎根本无法访问：

Macintosh-2:simple_cms kmcrayton7$ mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Macintosh-2:simple_cms kmcrayton7$ mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Macintosh-2:simple_cms kmcrayton7$ mysql -u root 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
Macintosh-2:simple_cms kmcrayton7$ mysql -u root 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
Macintosh-2:simple_cms kmcrayton7$ mysql -u root

Macintosh-2:simple_cms kmcrayton7$ mysql -u root -p
Enter password:

Macintosh-2:simple_cms kmcrayton7$ mysql -u root -p
Enter password:

Macintosh-2:simple_cms kmcrayton7$ 

Answer 1

我有同样的问题，它解决了：

GRANT ALL PRIVILEGES ON DBName.* TO 'UserName'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
