ERROR 1044 (42000): 拒绝用户访问

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'

按照回答#1 and #6中的步骤，结果如下：

mysql> select user,host,password from mysql.user;
+------------+-----------+-------------------------------------------+
| user       | host      | password                                  |

我不知道我在哪里犯错误

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:

Answer 1

我遇到了同样的问题，它解决了：

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

Answer 2

您的用户没有访问 simple_csm_development 数据库的权限。您需要使用授权语法来授予权限：

授予 priv_type [(column_list)] [, priv_type [(column_list)]] ... ON [object_type] priv_level TO user_specification [, user_specification] ... [要求{无| ssl_option [[AND] ssl_option] ...}] [有{授予选项|资源选项} ...]

在 user_specification 上授予代理 TO user_specification [, user_specification] ... [有授权选项]

对象类型：{ 表 |功能 |程序}

priv_level: { * | . | db_name.* | db_name.tbl_name | tbl_name | db_name.routine_name }

用户规格： 用户 [ auth_option ]

auth_option: { # MySQL 5.7.6 之前 由'auth_string'识别|由密码“hash_string”识别 |用 auth_plugin 识别 |标识为 auth_plugin AS 'hash_string' }

auth_option: { # 从 MySQL 5.7.6 开始 由'auth_string'识别|由密码“hash_string”识别 |用 auth_plugin 识别 |标识为 auth_plugin BY 'auth_string' |用 auth_plugin 标识为 '哈希字符串' }

ssl_option: { SSL | X509 |密码'密码' | ISSUER '发行人' | SUBJECT '主题' }

resource_option: { | MAX_QUERIES_PER_HOUR 计数 | MAX_UPDATES_PER_HOUR 计数 | MAX_CONNECTIONS_PER_HOUR 计数 | MAX_USER_CONNECTIONS 个 }

老实说，我不知道发生了什么变化，但是当我再次完成所有步骤时，它起作用了。我确定我这边有错误，但我现在找不到。谢谢！
