推荐答案

从 MySQL 8.0.4 开始，他们更改了默认值MySQL 服务器的身份验证插件从 mysql_native_password 到caching_sha2_password.

您可以运行以下命令来解决问题.

You can run the below command to resolve the issue.

示例用户名/密码 => student/pass123

sample username / password => student / pass123

ALTER USER 'student'@'localhost' IDENTIFIED WITH mysql_native_password BY 'pass123';
