Rails Capistrano 身份验证失败错误

Question

我正在关注tutorial，使用Capistrano3、Puma Web 服务器和nginx 在AWS 上托管我的Rails 6 应用程序。我处于最后阶段，但是当我尝试使用 Capistrano 部署我的 Ruby on Rails 应用程序时，不断收到 Authentication failed 错误。我使用的命令是cap production deploy。我创建了一个 ssh 密钥对，将公钥添加到包含应用程序代码的 Github 存储库中，并将私钥文件路径添加到文件中的以下 sn-p：/Users/edward/Project/EdwardBlog/blog/config/deploy/production.rb

set :ssh_options, { 
  forward_agent: true, 
  auth_methods: %w[publickey],
  keys: %w[/Users/edward/.ssh/id_rsa]
}

我可以像ssh -T git@github.com 那样通过 ssh 进入 github，并且我仔细检查了密钥对是否与我添加到我的 github 帐户的公共 SSH 密钥匹配。我还使用 ssh-add -l 将私钥添加到 ssh-agent

我也尝试使用我的密码部署应用程序，但是当我在提示符处输入我的 github 帐户密码时仍然没有运气：

set :ssh_options, {
   keys: %w(/Users/edward/.ssh/id_rsa),
   forward_agent: true,
   auth_methods: %w(password)
 }

我不知道为什么它不使用本地凭据进行身份验证。将不胜感激任何可能的解决方案或解决方法。

这是我在运行命令 cap production deploy --trace 时的消息：

Answer 1

用户 ubuntu@18.191.247.244 认证失败

这个问题是在你的部署目标中以ubuntu 进行炮击，它与 Github 无关。确保您可以使用ubuntu 用户访问该 IP，如果可以，请尝试将您的 SSH 密钥添加到您的代理（ssh-add ~/.ssh/id_rsa 或其他），以确保 Capistrano 可以与您的部署目标计算机建立 SSH 连接。
