运行 Capistrano 上限生产部署时 SSH 身份验证失败
SSH Authentication fails when running Capistrano cap production deploy
这是我第一次尝试使用 Capistrano 部署 Rails 应用程序。我正在按照 https://ogdenstudios.xyz/blog/how-do-i-deploy-a-rails-6-app-to-amazon-ec-2/ 上的教程部署到 AWS EC2 实例。我的应用程序在 Rails 6 和 运行s 上顺利地在本地主机上运行。我按照教程进行操作，但我在最后一步中存货，当我 运行 cap production deploy 出现以下错误时：

我是部署新手，不知道问题出在哪里。我创建了 SSH 密钥，并将其保存在我的 ubuntu 虚拟机和我的 Github 帐户中。
AWS ec2 实例需要 pem 密钥才能连接到它，所以你必须告诉 capistrano 使用什么密钥，我认为你需要将此配置添加到你的部署文件中：
set :ssh_options, { forward_agent: true, user: fetch(:user), keys: path_to_pem_key }
