记录一下本次为新应用新建数据库用户以及给新建用户分配权限的过程。

（1）新建一个数据库 travel_db

CREATE DATABASE `travel_db` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

（2）新建一个用户 travelUser1，只允许该用户 访问 travel_db 库

create user `travelUser1`;

update mysql.user set password=password('pwd123#.O') where User='travelUser1';

flush privileges;

show grants for `travelUser1`;

grant select,update,delete,insert on travel_db.* to `travelUser1`;

flush privileges;

show grants for `travelUser1`;

（3）设置 rijiAppUser 能够对 travel_db 库进行所有操作

flush privileges;

grant all on travel_db.* to `travelUser1`;

show grants for `travelUser1`;
