mysql 报错Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client
起因：mysql8.0加密方式的原因报错。
解决办法：
执行指令
mysql -u root -p
123456
use mysql;
alter user 'root'@'localhost' identified with mysql_native_password by '123456';
flush privileges;
注意：123456是我自己连接数据库的密码哈
