MYSQL设置密码时显示Failed! Error: SET PASSWORD has no significance for user 'root'@'localhost' as the authentication method used doesn't store authentication d

​

 用这个命令进入mysql

sudo mysql

在sql命令行输入以下命令回车，你就可以把密码改成mynewpassword

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password by 'mynewpassword';

exit回到终端命令行，输入：

sudo mysql_secure_installation

输入刚才的密码即可。
出现的问题都选n.
