我有StarCluster配置文件，如下所示：

[aws info]
AWS_ACCESS_KEY_ID = AKXXXXXXXXXXXXXXXXRQ

# replace this with your account number
AWS_USER_ID=006171111111
# Uncomment to specify a different Amazon AWS region (OPTIONAL)
# (defaults to us-east-1 if not specified)
# NOTE: AMIs have to be migrated!
AWS_REGION_NAME = ap-northeast-1
AWS_REGION_HOST = ec2.ap-northeast-1.amazonaws.com

## Defining EC2 Keypairs ##
###########################
# Sections starting with "key" define your keypairs. See "starcluster createkey

[key mykey]

# optionally specify shell (defaults to bash)
# (options: tcsh, zsh, csh, bash, ksh)

NODE_IMAGE_ID = ami-3393a45a
NODE_INSTANCE_TYPE = m1.small
使用以下命令启动群集没有问题：
AWS_REGION_NAME = us-east-1
AWS_REGION_HOST = ec2.us-east-1.amazonaws.com
但是当我把它改为：
AWS_REGION_NAME = ap-northeast-1
AWS_REGION_HOST = ec2.ap-northeast-1.amazonaws.com
我收到此错误：
$ starcluster start mycluster

>>> Using default cluster template: smallcluster

!!! ERROR - Cluster settings are not valid:
!!! ERROR - Keypair 'mykey' does not exist in region 'ap-northeast-1'
做正确的方法是什么？
答案 0 :(得分：1)
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，或者在该区域中导入密钥对。
您需要私钥（.pem文件）才能导入密钥对。
