当我试图通过SSH连接。 没关系，但经过我的一些操作： – [我已经下载密钥对，复制到.ec2，chmod到600，ssh-keygen -y -f〜/ .ec2 / gsg-keypair>〜/ .ec2 / gsg -keypair.pub我正在使用MacOS。 我认为这是权限的问题…但我已经尝试了所有组合和所有build议）

你需要修复你的sshdconfiguration。 您可以按照http://aws.amazon.com/instance-help/#no-response中的“EBS-Backed Instances :: Instance Recovery”部分执行此操作。
第4步：“更正旧的根卷上的configuration”。 是你需要去操纵你的sshd_config的地方。
由于实例和卷的操作是痛苦的缓慢，你应该testing你的去sird_config工作，通过使用configuration在不同的端口上启动sshd。 确保实例的安全组允许连接到该端口。
假设您正在使用Amazon Linux AMI，则会禁用rootlogin。 试试ssh -i gsg-keypair [email protected] -v
