1、用管理員登陸mysql

2、創建數據庫create database db01;

3、創建用戶

user01只能本地訪問

CREATE USER user01@'localhost' IDENTIFIED BY 'password1';

user02可以遠程訪問

CREATE USER user02@'%' IDENTIFIED BY 'password1';

4、修改user01密碼

SET PASSWORD FOR 'user01'@'localhost' = PASSWORD('password2');

5、授權

a)、user01管理db01全部權限

GRANT ALL PRIVILEGES ON db01.* TO user01;

b)、user02查看權限，并修改密碼

GRANT SELECT ON *.* TO 'user02'@'%' IDENTIFIED by 'password2';
