环境

问题

MySQL用户创建和授权

 

解决

 

1.以root用户登录创建新用户

 

C:\Users\Wentasy>mysql -uroot -p

mysql> CREATE USER music IDENTIFIED BY 'music';

 

2.以root用户登录创建数据库

 

create database music default charset utf8;

create table tb_user
(
	tb_user_id int(11) primary key auto_increment,
	tb_user_account varchar(32) not null,
	tb_user_password varchar(16) not null,
	tb_user_nick varchar(16) not null,
	tb_user_name varchar(32) not null,
	tb_user_gender bit(1),
	tb_user_phone varchar(16) ,
	tb_user_email varchar(40),
	check(tb_user_gender in('0', '1'))
);

create table tb_playlist
(
	tb_playlist_id int(11) primary key auto_increment,
	tb_user_id int(11) not null,
	tb_playlist_title varchar(255) not null,
	constraint FK_TB_USER_ID foreign key(tb_user_id) references tb_user(tb_user_id)
);

create table tb_records
(
	tb_records_id int(11) primary key auto_increment,
	tb_playlist_id int(11) not null,
	tb_records_name varchar(40) not null,
	constraint FK_TB_PLAYLIST_ID foreign key(tb_playlist_id) references tb_playlist(tb_playlist_id)
);

3.以root用户登录为用户授权

 

mysql> GRANT ALL PRIVILEGES ON music.* TO music@localhost IDENTIFIED BY 'music';

4.以新创建的用户登录查看数据库

 

C:\Users\Wentasy>mysql -umusic -p

C:\Users\Wentasy>mysql -umusic -p
