MySQL创建用户报错：ERROR 1396 (HY000): Operation CREATE USER failed for 'slave'@'%'

创建命令: 

CREATE USER 'slave'@'%' IDENTIFIED BY '123456';

 

报错：

mysql> CREATE USER 'slave'@'%' IDENTIFIED BY '123456';
ERROR 1396 (HY000): Operation CREATE USER failed for 'slave'@'%'

 

查看后数据库不存在，回忆了一下操作，手动删除过slave这用户，可能是这个操作引起的，现在执行命令重新删除一下

mysql> drop user 'slave'@'%';
Query OK, 0 rows affected (0.10 sec)
