capistrano问题

Question

我在将应用程序部署到服务器时遇到了问题。

我已经安装了msysgit，github和capistrano并正常工作。

我已经成功地将我的应用程序推送到github上，并且可以成功地从我的本地计算机上运行cap deploy:setup在我的服务器上进行设置。

但是..。

当我运行cap deploy:cold时，它会要求我提供密码以连接到github存储库，然后再次要求它连接到我的服务器，但随后它会给我一个错误，权限被拒绝(公钥)并返回。

这似乎是我的密钥的一个错误，但它如何连接到我的服务器进行cap deplo:setup？

我的公钥在github和我的服务器中是相同的，这是正确的吗？

另外，当运行cap deploy:setup时，它会询问我的用户服务器密码，这样做正确吗？

请帮帮忙，这件事已经拖了我好几天了

这是错误：

如果我将此代码添加到deploy.rb文件中

set :ssh_options, {:forward_agent => true}
on :start do    
  `ssh-add`
end

我得到了这个不同的错误

这个问题真的很老了，但我刚刚在windows7机器上又遇到了同样的问题。您应该添加forward_agent 并将ssh密钥的位置部署到您的部署配置文件中:以下是我在/.rb中的修复：

set :ssh_options,   :forward_agent => true 
set :ssh_options,   :keys => %w(c:/Users/USERNAME/.ssh/id_rsa)

除此之外，最好的解决方案是在linux环境中开发rails应用程序(并使用capistrano)。这将避免大量的此类技巧和单词，并将节省大量时间:)

访问部署主机上的存储库服务器不需要ssh密钥。您可以激活SSH forward_agent，让ssh_agent跟随您从一台机器到另一台mache。要使用capistrano执行此操作，可以将以下行添加到deploy.rb文件中

ssh_options:forward_agent =真
