Mysql 8.0 用戶授權命令

錯誤的寫法： 

GRANT ALL PRIVILEGES ON . TO ‘bbb’@’localhost’ IDENTIFIED BY ‘1qaz@WSX’;

 

正確的寫法：

create user ‘bbb’@’localhost’ identified by ‘1qaz@WSX’; 

grant all privileges on . to ‘bbb’@’localhost’ ;

 

在授權的語句中需要去掉 IDENTIFIED BY ‘password’;

 

授予某種權限： 

GRANT SELECT ON oilsystem.input TO ‘aaa’@’localhost’

 

刷新權限： 

FLUSH PRIVILEGES; 

 

查看權限：

SHOW GRANTS FOR 'bbb'@'localhost';

 

收回某種權限： 

REVOKE SELECT ON *.*  FROM ‘bbb’@’localhost’;
