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';

新建普通用戶：CREATE USER 'test1'@'localhost' IDENTIFIED BY 'test1'
數據庫創建：CREATE DATABASE example
表的創建：CREATE TABLE example0(id INT,
name VARCHAR(20),
sex BOOLEAN
)

DROP DATABASE IF EXISTS userdb;
CREATE DATABASE userdb;
USE userdb;
CREATE TABLE user(
id int(11)NOT NULL AUTO_INCREMENT,
userName varchar(20) DEFAULT NULL,
userPwd varchar(20) DEFAULT NULL,
PRIMARY KEY (id)
)ENGINE=MyISAM DEFAULT CHARSET=latin1;
INSERT INTO user(id,userName,userPwd)VALUES(1,'admin','admin');
