mysql 用户权限管理(账户创建,授权,删除,查看,撤销)

mysql grant,mysql revoke

账户权限管理

首先进入Mysql控制台：

mysql -uroot -p

grant授权格式：grant 权限列表 on 库.表 to 'user_name'@'host name' identified by "密码";

user_name是用户名，host_name为主机名，即用户连接Mysql时所在主机的名字。

创建一个新用户(user)并为此用户分配权限（这里先分配对所有数据库的表增删改查的权限），identified by 后面填入你新用户的密码

grant select,insert,update,delete on *.* to 'user'@'%' identified by 'your password';

如果是给予全部权限那么就这样

grant all privileges on *.* to 'user'@'%' identified by 'your password';

记得每次操作完要刷新授权

flush privileges;

查看用户权限

 show grants for user;

权限的撤销

当要撤销一个用户的权限。而又不希望将该用户从系统中删除时，可以使用revoke语句来实现

回收某些特定的权限

revoke回收权限格式：revoke 权限列表 on 库.表 from 用户名@'ip';

revoke select,insert,update,delete ON *.* from 'user'@'%';

回收特定用户的所有权限

revoke ALL PRIVILEGES ON *.* from 'user'@'%';
