1.创建用户的时候报错ERROR 1396 (HY000): Operation CREATE USER failed for 'user1'@'%'
mysql> create user user1 IDENTIFIED by '';
ERROR 1396 (HY000): Operation CREATE USER failed for 'user1'@'%'
2.上网查了一下说是没有这个用户之前有创建过,删除了,但是可能没有刷新权限,执行刷新权限, 发现还是创建不了
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec) mysql>
mysql>
mysql> create user user1 IDENTIFIED by '';
3.再次删除用户,再刷新,再创建就可以了
mysql> drop user user1;
Query OK, 0 rows affected (0.02 sec) mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec) mysql> create user user1 IDENTIFIED by '';
Query OK, 0 rows affected (0.01 sec)
完!
