AWS Ec2 ubuntu实例

Question

I am getting this error while connecting(through ssh) to an EC2 instance: No authentication methods available(server sent public key) and I am not able to locate the .PEM file stored in ubuntu Ec2 instance? Please help me to solve this problem.

Answer 1

I found answer for the above question..We have to transfer the downloaded .PEM file from local filesystem (ie Windows) to Amazon Ec2 instance (ie Ubuntu) using SCP or Filezilla . Check the below link

http://angus.readthedocs.org/en/2014/amazon/transfer-files-between-instance.html

After moving .PEM file to specific location ( For Ex: home/ubuntu/.ssh or ~/.ssh ) in ubuntu.. use following command to SSH

ssh -i /path/to/.PEM username@DNS-name-of-instance

OR

ssh -i /path/to/.PEM username@private-ip-of-instance

Answer 2

EC2机器不包含.PEM文件。用户必须在创建EC2实例时下载它，它是一个可下载的文件。使用此文件的用户可以与EC2机器通信。对于Windows用户，将.pem文件转换为。 ppk文件使用putty keygen.for linux用户，可以直接使用。
