【问题描述】：

我正在尝试将我的应用程序部署到 ubuntu 服务器，但出现错误。我已在服务器授权密钥中添加了我的密钥。我将 Google 计算机服务器用于服务器目的。我无法找到任何解决方案，所有解决方案都导致服务器 ssh 文件夹中的授权密钥，我已经添加了它。有没有人面临同样的问题？这是一个代码：

Ayazs-MBP:peatio_exchange ayaz$ cap production deploy
00:00 rbenv:validate
      rbenv: rbenv_ruby is not set; ruby version will be defined by the remote …
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy@35.190.186.40: Authentication failed for user deploy@35.190.186.40


Caused by:
Net::SSH::AuthenticationFailed: Authentication failed for user deploy@35.190.186.40

【解决方案1】：

这可能是很多事情，但从外观上看，您可能添加的公钥不适合deploy 用户。确保它存在于/home/deploy/.ssh（或其主目录中）

确保您能够使用ssh deploy@35.190.186.40 登录到服务器——如果您为部署用户生成了单独的密钥，您可以使用-i 标志来指定密钥文件的路径。

ssh -i ~/Desktop/deploy_id_rsa.pub deploy@35.190.186.40
