此时创建完了用户之后，我们用数据库连接工具连接：

mysql创建用户并且授予权限

此时创建数据：

mysql创建用户并且授予权限

授予权限

说明没有创建数据库的权限，此时进入root用户，创建好数据库，然后授予权限，如下所示：

mysql>CREATE DATABASE bd-portal DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
mysql>GRANT ALL PRIVILEGES ON `bd-portal`.* TO 'bd-portal'@'%' IDENTIFIED BY 'bd-portal';
mysql>FLUSH PRIVILEGES;

备注：mysql56同样有这方面限制。
