Mysql添加用户和数据库

1. 先创建数据库
2. 创建用户并赋予一个数据库的所有权限

use mysql;
create database databaseName character set utf8;
grant all privileges on databaseName.* to username@'ip' identified by 'password';

举例:

use mysql;
create database test_db character set utf8;
grant all privileges on test_db.* to testuser@'localhost' identified by '123456';
