今天游戏和服，发现数据备份好后，导入不到目标库中，

mysql -h10.66.125.733 --port 3306 -u sanda -pX12234455 --default-character-set=utf8 sanda_s10 < /data/mysql/8/user.sql

返回

ERROR 1044 (42000) at line 20: Access denied for user 'sanda'@'10.105.%' to database 'sanda_s10'

经查缺少了，以下两个权限：

mysql> grant LOCK TABLES on *.* to sanda@'10.105.%';
mysql> grant alter on *.* to sanda@'10.105.%';

或者就授予全部权限

grant all privileges on *.* to 'sanda'@'%' identified by 'X12234455';<..
