我有 StarCluster 配置文件，如下所示：

我启动集群没有问题：
AWS_REGION_NAME = us-east-1
AWS_REGION_HOST = ec2.us-east-1.amazonaws.com
但是当我将其更改为：
AWS_REGION_NAME = ap-northeast-1
AWS_REGION_HOST = ec2.ap-northeast-1.amazonaws.com
我收到此错误：
$ starcluster start mycluster

正确的方法是什么？
密钥对分别存储在每个区域中。您需要在ap-northeast-1区域中创建新的密钥对，或在该区域中导入密钥对。
您将需要私钥(.pem文件(来导入密钥对。
