Question

我一直在尝试使用Capistrano部署Rails应用程序但是当我运行cap production deploy时，我得到了：

(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as 
deploy@12.34.56.789: Authentication failed for user deploy@12.34.56.789

Net::SSH::AuthenticationFailed: Authentication failed for user 
deploy@12.34.56.789

Tasks: TOP => rvm:check
(See full trace by running task with --trace)

我试图运行cap production rvm:check --trace而我得到了这个

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke bundler:map_bins (first_time)
** Execute bundler:map_bins
** Invoke rvm:hook (first_time)

** Invoke rvm:check (first_time)
** Execute rvm:check

Tasks: TOP => rvm:check

这是deploy.rb的ssh部分：

set :keep_releases, 5
set :rvm_type, :user
set :rvm_ruby_version, 'ruby-2.3.1'
set :ssh_options, { forward_agent: true }
# set :ssh_options, { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/mykey.pem) }

我在config/deploy/production.rb

中有这一行

server "12.34.56.789", user: "deploy", roles: %w{app db web}, my_property: :my_value

当我运行eval ssh-agent``和ssh-add ~/.ssh/id_rsa时，它运行正常。

我在这里遗漏了什么？我该如何解决这个问题？

谢谢。

我有一个类似的问题。该答案总结了@PavelS和@Kehinde的上述评论，并使其更普遍适用：

请确保您可以ssh 使用日志文件或stderr中的凭据。在这个问题中，这必须起作用：ssh deploy@12.34.56.789。如果这不起作用，则可能有多种原因。
在OP的情况下，他显然需要启用ssh ，如此处详细说明：不使用密码的SSH登录：{{3 }}。
在我的情况下，我们用于部署的一台服务器已关闭，并且部署代码使用了此无法正常运行的服务器。因此ssh显然不起作用，但是原因有所不同。我将代码更改为使用备用的有效部署服务器，对此有效：ssh deploy@another.server.that.works。
