mysql报错ERROR 1045 (28000)

新安装了一个mysql,创建了一个新的用户dadmin,授予ALL权限

mysql>GRANT ALL ON *.* TO ‘dadmin‘@‘localhost‘ IDENTIFIED BY ‘123456‘;

mysql>DROP USER ‘root‘@‘localhost‘;

mysql>DROP USER ‘root‘@‘localhost.localdomain‘;

mysql>DROP USER ‘root‘@‘::1‘;

mysql>DROP USER ‘root‘@‘127.0.0.1‘;

后面才想起来,忘记给‘dbaadmin‘@‘%‘远程权限，然后开始授权

mysql> GRANT ALL ON *.* TO ‘dadmin‘@‘%‘ IDENTIFIED BY ‘123456‘;

ERROR 1045 (28000): Access denied for user ‘dadmin‘@‘localhost‘ (using password: YES)

出现这个问题，这样解决：

mysql>use mysql

mysql> update user set grant_priv = ‘Y‘ where user = ‘dadmin‘;

[root@localhost ~]# mysql -udadmin -p
