mysql 命令集

1、查看mysql所有用戶及權限
SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;


2、查看數據庫中具體某個用戶的權限
show grants for 'root'@'%';


3、刷新權限
flush privileges;


4、創建用戶
create user 'datauser'@'10.10.11.%' identified by 'db-password';


5、顯示當前用戶
select user();


6、權限
grant all privileges on *.* to 'user'@'%' identified by 'password' with grant option;
grant all privileges on database.table to 'user'@'%' identified by 'password' with grant option;


7、修改密碼：
mysqladmin -u root -p 123 password 456 （使用mysqladmin語法：mysqladmin -u用戶名 -p舊密碼 password 新密碼）
set password for root@localhost=password('');


8、刪除用戶和撤銷權限
drop user username@'%'
delete from user where user='sss' and host='localhost';
