【MYSQL用户创建报错】ERROR 1396 (HY000): Operation CREATE USER failed for 'user1'@'%'

原文参考自：http://blog.csdn.net/u011575570/article/details/51438841

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 '123456';
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 '123456';

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 '123456';
Query OK, 0 rows affected (0.01 sec)

完！
