MySQL root用戶不能爲普通用戶賦權限

MySQL root用戶不能爲普通用戶賦權限，

報錯：Error Code: 1044. Access denied for user ‘root’@’%’ to database

mysql> select host,user,password,Grant_priv,Super_priv FROM mysql.user;

可以看到root遠程授權的權限沒有打開：

 %            | root  | N   

賦值一下權限即可。

update mysql.user set Grant_priv='Y', Super_priv='Y' where User='root';
flush privileges;
