1、用户创建
CREATE DATABASE db_test; CREATE USER user IDENTIFIED BY 'passwd';
?? ?注:user为用户名, passwd为密码
?? ?这样创建的用户是不限制用户访问的IP,也就是'%',上面等价于:
CREATE USER utel@'%' IDENTIFIED BY 'utel789';
?? ?如果只能本地访问,可以
CREATE USER utel@'localhost' IDENTIFIED BY 'utel789';
2、授权
GRANT ALL PRIVILEGES on db_test.* TO user@'%';?? ?授权user可以操作db_test库的所有权限
3、删除用户
?? ?1)删除授权
revoke privileges (columns) on what from user;??? ?2)删除用户
delete from mysql.user where user='user' and host='%';?4、查看
select host, user from mysql.user;?
5、修改密码
set password for user@'%'=Password('passwd_new');?
