mysql>中创建密码报错，解决办法：

 mysql> create user identified by password "12345qwert";
ERROR 1372 (HY000): Password hash should be a 41-digit hexadecimal number
注释：密码哈希算法为41位十六进制加密算法。
也就是说密码应该为加密的密码。

解决措施：查找到明文的密码加密后的对应值

mysql> select password('12345qwert');
+-------------------------------------------+
| password('12345qwert')                    |
+-------------------------------------------+
| *41DA2FB717B0761640FBDD9C889C372DC8CB6FAA |
+-------------------------------------------+
然后再去创建用户：
mysql>  create user identified by password '*41DA2FB717B0761640FBDD9C889C372DC8CB6FAA';
Query OK, 0 rows affected (0.00 sec)

mysql> select host,user,password from mysql.user;
