mysql - 如何在 MySQL 8.0 中授予 root 用户所有权限

Question

试过

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

得到

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'root' WITH GRANT OPTION' at line 1.

注意:在以前的版本中尝试时也是如此。

也试过了

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

得到

ERROR 1410 (42000): You are not allowed to create a user with GRANT

MySQL (8.0.11.0) 用户名​​/密码是 root/root。

Answer 1

从 MySQL 8 开始，您不再可以(隐式)使用 GRANT 命令创建用户。使用CREATE USER相反，后跟 GRANT声明:

mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'PASSWORD';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

注意关于WITH GRANT OPTION的安全风险，参见:

• Grant all privileges on database
