MySQ权限控制语句
1.使用root账号登陆到MySQL服务器:
mysql -u root -pmypass;
2.切换到mysql数据库实例:
use mysql;
3.查看用户表:
select host, user, password from user;
4.创建一个只允许从本机登录的用户“yang”,密码为“yangpass”:
create user 'yang'@'localhost' identified by 'yangpass';
5.删除一个名为“yang”的本机登录用户:
drop user 'yang'@'localhost';
6.创建一个允许从任何主机登录的用户“yang”,密码为“yangpass”:
create user 'yang'@'%' identified by 'yangpass';
7.修改允许从任何主机登录的用户“yang”的密码,新密码为“yan”:
set password for 'yang'@'%' = password('yan');
8.向允许从任意主机登录的名为“yang”的用户,授予yang_test的库的所有权限:
grant all privileges on yang_test.* to 'yang'@"%";
9.刷新权限,使权限修改生效:
flush privileges;
10.创建一个允许从任何主机登录的用户“remote”,密码为“app”:
create user 'remote'@'%' identifed by 'app';
11.给“remote”用户授予库“yang_test”上的“t_weapon”表的CRUD权限:
grant select, delete, update, insert on yang_test.t_weapon to 'remote';
12.撤销用户“yang”在“yang_test”库上的所有权限:
revoke all privileges on yang_test.* from 'yang'@'%';
