Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication解决办法

node连接数据库报错。

Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server;

数据库版本

mysql --version
mysql  Ver 8.0.21 for Linux on x86_64 (MySQL Community Server - GPL)

原因
mysql8.0以上加密方式，Node还不支持。

alter user 'root'@'localhost' identified with mysql_native_password by 'xxx';

登陆mysql，执行这个命令就好了。
