Question

我有一个安装了mysql的ubuntu服务器，有一次我看到服务器上运行的php代码可以访问mysql，但我无法远程访问mysql，另一台服务器或sequal pro。

$ mysql -u root -p
mysql> GRANT ALL on *.* TO 'thomas'@'%';
mysql> exit
$ mysql -u thomas -p
mysql> show grants;
+------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for thomas@localhost                                                                                                              |
+------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'thomas'@'localhost' IDENTIFIED BY PASSWORD '[ENCRYPTEDPASSWORD]' WITH GRANT OPTION |
+------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> exit
$ mysql -u thomas -p -h [SERVERIP]
ERROR 1045 (28000): Access denied for user 'thomas'@'[SERVERNAME]' (using password: YES)

更新

我进入并删除所有用户（有些没有密码）的用户我在mysql.user表并使用drop user命令。

CREATE USER 'thomas'@'localhost' IDENTIFIED BY '[PASSWORD]';
GRANT ALL PRIVILEGES ON *.* TO 'thomas'@'localhost' IDENTIFIED BY '[PASSWORD]';
GRANT ALL PRIVILEGES ON *.* TO 'thomas'@'[SERVERIP]' IDENTIFIED BY '[PASSWORD]';
GRANT ALL PRIVILEGES ON *.* TO 'thomas'@'%' IDENTIFIED BY '[PASSWORD]';

表现在看起来像这样：

+--------------+------------------+
| Host         | User             | 
+--------------+------------------+
| localhost    | root             | 
| localhost    | phpmyadmin       | 
| 127.0.0.1    | root             | 
| ::1          | root             | 
| localhost    | debian-sys-maint | 
| localhost    | thomas           | 
| [SERVERIP]   | thomas           | 
| %            | thomas           | 
+--------------+------------------+

Answer 1

嗯，你有

GRANT ALL PRIVILEGES ON *.* TO 'thomas'@'localhost'

但你不在localhost。您可能想尝试

GRANT ALL PRIVILEGES ON *.* TO 'thomas'@'%'

当然，如果你愿意，你必须添加IDENTIFIED BY 'password'

远程访问数据库
