1、创建用户时报错

grant select on lon.* to 'data'@'%' identified by 'Bi';
[Err] 1044 - Access denied for user 'lon'@'%' to database 'lon'

以root用户登录mysql的，怎么还会遇到这问题

2、查看权限

mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;+--------------+---------+-------------------------------------------+------------+------------+| host         | user    | password                                  | Grant_priv | Super_priv |+--------------+---------+-------------------------------------------+------------+------------+| 192.168.28.% | oozie   | *FED29C14B2E900D70B11B1F1B370F953BA51A6A0 | N          | Y          || 192.168.28.% | hive    | *FED29C14B2E900D70B11B1F1B370F953BA51A6A0 | N          | Y          || 192.168.28.% | root    | *FED29C14B2E900D70B11B1F1B370F953BA51A6A0 | Y          | Y          || localhost    | ranger  | *84BB87F6BF7F61703B24CE1C9AA9C0E3F2286900 | N          | N          || localhost    | root    | 0                                         | Y          | Y          || %            | root    | *FED29C14B2E900D70B11B1F1B370F953BA51A6A0 | N          | Y          || 127.0.0.1    | root    | *FED29C14B2E900D70B11B1F1B370F953BA51A6A0 | Y          | Y          || %            | ranger  | *84BB87F6BF7F61703B24CE1C9AA9C0E3F2286900 | N          | Y          |+--------------+---------+-------------------------------------------+------------+------------+

可以看到授权的权限没有打开： Grant_priv is set to N for root@%. 修复下

3、打开权限

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';FLUSH PRIVILEGES; 4、重新创建用户即可；
