我想使用Perl访问一个AWS实例。我可以像这样从命令行访问实例:
ssh -i my-key-pair.pem ubuntu@ec2-**-***-***-***.us-west-2.compute.amazonaws.com
但是我的代码不工作:
#! usr/bin/perl
use Net::SSH::Perl;
$user = "ubuntu";
$host = "ec2-**-***-***-***.us-west-2.compute.amazonaws.com";
@KEYFILE = "my-key-pair.pem";
$ssh = Net::SSH::Perl->new($host, debug=>1, identity_files=>@KEYFILE);
$ssh->login($user);
正如我提到的，我对这个概念很陌生，这可能是一个简单的解决方案，我在网上找不到解决方案，希望你能帮助我。
输出如下:

似乎指向了这个问题。您的私钥由密码短语保护，当您尝试使用它时，它想要向您询问它，但不能在批处理模式下。
我认为你必须从你的私钥中删除密码短语才能使用这个模块。有许多工具，包括OpenSSL，可以为您做到这一点。只需在文档中搜索从密钥中删除密码短语。
