授予数据库上的所有权限，这并不授予我特定IP的任何特权

Question

我正在尝试将所有特权授予特定的IP，但是当我尝试获取特权IP的列表时，它始终仅显示本地主机，我按照此问题中的说明进行操作，但未做任何更改，我在做什么错？

MariaDB [(none)]> GRANT ALL ON database.* TO 'root'@'192.168.3.1' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> show grants;
+---------------------------------------------------------------------+
| Grants for root@localhost                                           |
+---------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION |
| GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION        |
+---------------------------------------------------------------------+
2 rows in set (0.00 sec)

mysql> show slave status;
ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER,REPLICATION CLIENT privilege(s) for this operation
mysql> show grants;
+------------------------------------------------------------------+
| Grants for root@192.168.1.5                                      |
+------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'root'@'192.168.1.5'                       |
| GRANT ALL PRIVILEGES ON `western_star`.* TO 'root'@'192.168.1.5' |
+------------------------------------------------------------------+
2 rows in set (0.00 sec)

注意：

即使我以我的用户远程登录并且拥有权限，我仍然会被拒绝。

mysql> show slave status;
ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER,REPLICATION CLIENT privilege(s) for this operation
mysql> show grants;
+------------------------------------------------------------------+
| Grants for root@192.168.1.5                                      |
+------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'root'@'192.168.1.5'                       |
| GRANT ALL PRIVILEGES ON `western_star`.* TO 'root'@'192.168.1.5' |

Answer 1

尝试运行以下语句：

SHOW GRANTS FOR 'root'@'192.168.3.1' ;

并与从中得到的回报进行比较：

SHOW GRANTS FOR 'root'@'localhost' ; 

SHOW GRANTS显示当前用户的授权。

请注意，“ root @ localhost” 和“ root@192.168.3.1” 不是同一用户。MySQL通过用户和主机识别用户。（这是两个不同的用户。）

SUPER和REPLICATION CLIENT特权是全局特权，而不是数据库特权。授予这些特权的语法为ON *.*。例如：

GRANT REPLICATION CLIENT ON *.* TO 'root'@'192.168.1.5' ;
