MySQL8创建密码无效的新用户

我使用MySQL已有好几年了,创建新用户的命令直到MySQL 5.x版本如下:

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';

最近我安装了MySQL 8.在那,这个命令不起作用.

在触发上述命令时抛出以下错误:

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 'password'' at line 1

MySQL 8中的语法有什么变化吗？在MySQL 8中创建新用户命令的正确语法是什么？

注意:我在MySQL 5.x版本中尝试了这种语法.它正常工作.

试试这个:

use mysql;
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'@'localhost';
flush privileges;
