You must SET PASSWORD before executing this statement的解决方法

参考前文利用安全模式成功登陆，然后修改密码，等于给MySql设置了密码。登陆进去后，想创建一个数据库测试下。得到的结果确实：

ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

非常诡异啊，明明用密码登陆进去了，怎么还提示需要密码。

mysql> create database yan1;

ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

mysql> SET PASSWORD = PASSWORD('123456');

Query OK, 0 rows affected (0.03 sec)

mysql> create database yan1;

Query OK, 1 row affected (0.00 sec)

也就是用mysql> SET PASSWORD = PASSWORD('123456');这句话重新设置一次密
