解決方案

修改plugin欄位為mysql_native_password

mysql> alter user 'root'@'%' identified with mysql_native_password by 'you password';
Query OK, 0 rows affected (0.27 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


mysql> select user,host,plugin from user where user='root';
+------+-----------+-----------------------+
| user | host      | plugin                |
+------+-----------+-----------------------+
| root | %         | mysql_native_password |
| root | localhost | mysql_native_password |
+------+-----------+-----------------------+
