MySQL some pain in the comprehension

1.mysql> CREATE DATABASE AA;

ERROR 1044 (42000): Access denied for user "@ ' localhost ' to database ' AA '

This is the meaning of the anonymous user ~ ~ ~ Although you think you are the root login

Workaround: Change to Real root login

F:\softwares\mysql5\mysql-5.6.24-winx64\bin>mysql--user=root-penter password:welcome to the MySQL monitor.

Note that MySQL--user=root-p is to allow you to log in as root, so the following password is the root password, default is null, direct enter.

F:\softwares\mysql5\mysql-5.6.24-winx64\bin>mysql--user=root-penter Password: ******error 1045 (28000): Access Denied for user ' root ' @ ' localhost ' (using Password:yes)

This means that the password is incorrect.
