如何使用 AWS 上的密钥对访问 SFTP 服务器上的客户端以进行 s3 存储桶访问？

Question

我们想通过基于公钥认证的AWS SFTP服务器来访问客户端访问AWS上的s3存储桶，如何基于公钥认证访问客户端，我们将遵循哪些步骤？

Answer 1

If you are using AWS Transfer for SFTP , then you should:

• Ask the user to generate an RSA keypair and provide you with the public key
• Create a user in the AWS Transfer server and attach the public key

The user should then be able to connect to the server by using their private key.

I think you'll also need to create an IAM Role that grants the user access to the appropriate S3 bucket. See: Working with service-managed users - AWS Transfer Family

Answer 2

I created the key pair using ssh-keygen, then these two keys are store in same folder. following script is passed then file is automatically transferred to cliet folder

echo " Privatekey,PublicKey (copied)"
               
           chmod 600 $folder/id_rsa
# private key permission changed    
           filechmod_result=`echo $?`
        if [[ $filechmod_result -eq  0 ]];
                then
                     echo "chmod is success 12345678"
                else
                 echo "chmod is fail"
                 fi 
             
 sftp -o Port=8022 -o IdentityFile=$folder/id_rsa -o StrictHostKeyChecking=no $username@$servername << !
            cd client folder
            put $folder/$client folder
            ls
