一、创建用户并授权

1. 登录mysql


mysql -u root -q

输入密码

2. 创建数据库(已有数据库就不需要建立)


create database newDB;//以创建newDB为例

3. 创建用户

创建userone,只能本地访问


create user userone@'localhost' identified by 'password';

创建usertwo,可以远程访问

create user usertwo@'%' identified by 'password';

4. 修改用户密码

以userone为例:


set password for 'userone'@'%'=password('1234')

5. 为用户授权

授予userone管理newDB的全部权限

grant all privileges on dbdata.*@'%' to userone identified by '1234';

授予userone全部数据库权限,并修改密码


grant all on *.* to 'usertwo'@'%' identified by '123456';
