MySQL 基础操作

Mysql 新建用户，授权，让某个用户只能访问指定的数据库
localhost版，只能在本地登录使用：
insert into mysql.user(Host,User,Password) values("localhost","test3",password("test3"));
grant select on ‘kuaibei‘.* to test3@localhost identified by ‘test3‘;
flush privileges;
%版，任何IP地址都能登录使用：

insert into mysql.user(Host,User,Password) values("%","test3",password("test3"));

grant select on ‘kuaibei‘.* to test3@"%" identified by ‘test3‘;

flush privileges;

MySQL修改root密码???
mysql -u root
mysql> use mysql;
mysql> UPDATE user SET Password = PASSWORD(‘newpass‘) WHERE user = ‘root‘;
mysql> FLUSH PRIVILEGES;
