调用HeadObject操作时发生客户端错误(301):

我使用IAM角色、托管策略和实例配置文件来为s3 bucket提供实例可访问性:

Moved Permanently 通常表示您被重定向到对象的位置。这通常是因为请求被发送到位于 不同地区 .

添加 --region 参数,其中区域与存储桶的区域匹配。例如:

aws s3 cp s3://mybucket/login.keytab destination_directory/ --region ap-southeast-2

/root/.aws/credentials 文件和添加类似区域 region = ap-southeast-2
