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‘;

mysql> quit //退出，再次连接
Bye
