mysql將某數據庫的全部權限賦給某用戶，提示1044錯誤Access denied

 

mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';
ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'zabbix'

 

 

查看root用戶有沒有授權權限

 

mysql> select host,user,grant_priv,Super_priv from mysql.user;
+-----------+----------+------------+------------+
| host      | user     | grant_priv | Super_priv |
+-----------+----------+------------+------------+
| 127.0.0.1 | root     | Y          | Y          |
| localhost | root     | N          | Y          |
| 10.0.3.%  | repluser | N          | N          |
+-----------+----------+------------+------------+
3 rows in set (0.00 sec)

可以看到localhost的grant_priv的值為N，也就是說root用戶不能授權給其他用戶，所以我們需要把這個值改為Y

 

 

mysql> update mysql.user set grant_priv='N' where host='localhost';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 1  Changed: 0  Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

改完之后最好重啟一下服務器（我沒重啟，所以還是報那個錯，重啟后就正常了）

 

 

mysql> select user,host,Grant_priv,super_priv from mysql.user;
+----------+-----------+------------+------------+
| user     | host      | Grant_priv | super_priv |
+----------+-----------+------------+------------+
| root     | 127.0.0.1 | Y          | Y          |
| root     | localhost | Y          | Y          |
| repluser | 10.0.3.%  | N          | N          |
