Rails 應用程序中的 Capistrano 部署錯誤

Question

我在我的 Rails 應用程序中進行 cap 生產部署時遇到此錯誤，我的 net-ssh 版本是 5.0.2，誰能幫我解決這個問題。 我的服務器是彪馬

Answer 1

對我來說只是在終端上執行

ssh-add

這奏效了。

Answer 2

至少在 Mac OS 上，如果您在系統啟動后不 ssh-add [yourkey]，您將收到此錯誤。

Answer 3

盡管您可以通過添加其他答案建議的 gem 來解決此錯誤，但您不一定需要這樣做。

另一種方法是遵循 Puppet 的 Bolt 工具的已知問題中給出的建議，尤其是這個。

以防萬一鏈接消失，解決方案是以 PEM 格式而不是 OpenSSH 生成您的 SSH 密鑰。 您可以通過向ssh-keygen命令添加一個額外選項來實現此目的：

ssh-keygen -t rsa -m PEM

我已經能夠成功地使用這種技術來避免添加額外的寶石。

Answer 4

我的工作解決方案：

文件

  gem 'net-ssh', '>= 6.0.2'
  gem 'ed25519', '>= 1.2', '< 2.0'
  gem 'bcrypt_pbkdf', '>= 1.0', '< 2.0'

Answer 5

將這些寶石添加到您的 Gemfile 中，

gem 'rbnacl', '< 5.0', :require => false                                                                                                                                                                
gem 'rbnacl-libsodium', :require => false                                                                                                                                                               
gem 'bcrypt_pbkdf', '< 2.0', :require => false

然后運行bundle install並重試。

Answer 6

這與我解決了同樣的問題

ssh-agent -s  && ssh-add ~/.ssh/id_rsa

Answer 7

在多用戶開發服務器中，沒有root權限，這解決了：

eval `ssh-agent -s`
ssh-add

Answer 8

gem install ed25519 bcrypt_pbkdf

對於使用 ed25519 算法生成的新密鑰，這修復了它
