当然出于安全考虑，程序也可以不连接数据库的root用户，可以使用其他用户操作，这里新建一个用户：
use mysql;
select host, user from user;
create user apm identified by 'paasapm';
grant all on ShoppingMallDB.* to apm@'%' identified by 'paasapm' with grant option;
flush privileges;

use information_schema;
show variables like 'validate_password%;

set global validate_password_length=6;
set global validate_password_policy=0;
