Mysql - GRANT ALL PRIVILEGES结果为ERROR 1044（42000）：拒绝访问用户＆root;＆＃39; @＆＃39; localhost＆＃39;

Question

我创建了一个MySQL数据库＆＃34; gefdb＆＃34;和用户＆＃34; testuser＆＃34; 我完成的用户创建：

> CREATE USER 'testuser'@'localhost' IDENTIFIED BY '********'; 
> CREATE USER 'testuser'@'%' IDENTIFIED BY '********';

我登录为＆＃34; root＆＃34;为了授予＆＃34; gefdb＆＃34;的所有权限用户＆＃34; testuser＆＃34;。

mysql -h localhost -u root -p

mysql> GRANT ALL PRIVILEGES ON `gefdb`.* TO 'testuser'@'localhost' WITH GRANT OPTION;
ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'gefdb'

我试图验证一些事情：

mysql> use mysql;
mysql> SELECT user,host FROM db WHERE db='gefdb';
+----------+-----------+
| user     | host      |
+----------+-----------+
| testuser | %         |
| testuser | localhost |
+----------+-----------+

mysql> SELECT host,user,Grant_priv,Super_priv FROM mysql.user;
+-------------------+------------+------------+------------+
| host              | user       | Grant_priv | Super_priv |
+-------------------+------------+------------+------------+
| localhost         | root       | Y          | Y          |

mysql> select user(), current_user();
+----------------+----------------+
| user()         | current_user() |
+----------------+----------------+
| root@localhost | root@localhost |
+----------------+----------------+

我不知道为什么我不能将gefdb上的PRIVILEGES设置为testuser。任何的想法？ 问题是我用＆＃34; testuser＆＃34;

登录后无法使用gefdb

mysql -h localhost -u testuser -p

mysql> use gefdb;
#1044 - Access denied for user 'testuser'@'localhost' to database 'gefdb'

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
+--------------------+
1 row in set (0.00 sec)

似乎用户＆＃34; testuser＆＃34;无法访问＆＃34; gefdb＆＃34;但我不知道自己做错了什么。
