我使用 Ubuntu 16.04。
我想通过单独的配置文件建立与亚马逊服务的 ssh 连接。
我还需要将文件从一台服务器传输到另一台服务器，这个帖子建议使用单独的配置文件。
当我使用它时它连接
ssh -i ~/Desktop/ssh_keys/prod.pem ec2-user@***.***.***.***
但当我使用单独的配置时则不然：
ssh -F ~/Desktop/ssh_keys/scp_config prod
scp_配置：
Host prod
HostName ***.***.***.***
User ec2-user
CertificateFile ~/Desktop/ssh_keys/prod.pem

我的设置有什么问题？
答案1
您应该使用 IdentityFile 参数来指定您的私钥。
身份文件 指定从中读取用户 RSA 身份验证身份的文件。
scp_配置：
Host prod
HostName ***.***.***.***
User ec2-user
IdentityFile ~/Desktop/ssh_keys/prod.pem
CertificationFile 指定从中读取用户证书的文件。必须单独提供相应的私钥才能从 IdentityFile 指令或 -i 标志将此证书用于 ssh
IdentityFile 还可以与 CertificationFile 结合使用，以提供身份认证所需的任何证书。
