MySQL报错ERROR 1396 (HY000): Operation CREATE USER failed for 'zabbix'@'localhost'

解决方法：

mysql> create user zabbix@localhost identified by '1076128880';
ERROR 1396 (HY000): Operation CREATE USER failed for 'zabbix'@'localhost'
mysql> drop user zabbix@localhost;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> create user zabbix@localhost identified by '1076128880';
Query OK, 0 rows affected (0.01 sec)
官方说这是MySQL的一个bug
