如何在 MySQL 8.0 中授予 root 用户所有权限

问题描述

尝试过

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

获取

ERROR 1064 (42000):您的 SQL 语法有错误；检查手册对应于您的 MySQL 服务器版本，以便在第 1 行的IDENTIFIED BY 'root' WITH GRANT OPTION"附近使用正确的语法.

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.

Note: The same is working when tried in previous versions.

也试过了

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

获取

ERROR 1410 (42000):您不能使用 GRANT 创建用户

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.

MySQL (8.0.11.0) username/password is root/root.

推荐答案

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

Starting with MySQL 8 you no longer can (implicitly) create a user using the GRANT command. Use CREATE USER instead, followed by the GRANT statement:

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

注意有关WITH GRANT OPTION的安全风险，请参阅:
