Ruby on rails 卡皮斯特拉诺问题

我在将应用程序部署到服务器时遇到问题

我已经安装了msysgit、github和capistrano并开始工作

我已成功将我的应用程序推送到github，并且可以成功运行

cap deploy:setup

从本地计算机在我的服务器上安装

但是

当我运行

cap deploy:cold

时，它会询问我要连接的密码短语 github repo然后它再次要求它连接到我的服务器，但是 给我一个错误权限被拒绝（公钥）并返回

看来这是我钥匙的错误，但怎么可能呢 连接到我的服务器以执行

cap deplo:setup

我的公钥在github和我的服务器中都是相同的，是这样吗 对吗

另外，在运行

cap deploy:setup

时，它会询问我的用户服务器 密码正确吗

请帮忙，因为这已经耽搁了我好几天了

这就是错误：

非常感谢rick，你应该在你的服务器（你想要部署的地方）上安装你的git服务器访问密钥

您应该拥有您的密钥文件（使用chmod 600）：

id_rsa id_rsa.pub 在部署用户主页的服务器上的~/.ssh目录中（使用chmod 700）

您可能只有本地开发计算机上才有该密钥

您可以为“setup:cold”添加部署文件钩子，其中将自动

---

上载本地密钥文件

如果我将其添加到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

不需要ssh密钥就可以访问deploy mahcine上的存储库服务器。您可以激活SSH转发代理，使SSH代理跟随您从机器到机器。要使用capistrano执行此操作，可以将此行添加到deploy.rb文件中

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

ssh_选项[：转发_代理]=真

---

这个问题真的很老了，但我在Windows7机器上又遇到了同样的问题。您应该将转发代理和ssh密钥的位置添加到部署配置文件中：这是我在config/deploy.rb上的修复程序：

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）。这将避免大量此类恶作剧，节省大量时间：）

为什么您在我的本地计算机和服务器上都有公钥和私钥？这些应该完全相同吗？我以为你只是在本地机器上有公共-私有，然后把pulic复制到服务器上？问题是我可以用sshuser@server然后输入我的密码，它将以这种方式连接到服务器？？？您希望使用git部署，capistrano不希望从服务器端而不是从您的计算机上获取代码，这就是为什么您应该在服务器帐户上拥有git访问密钥的原因。您必须将ssh从您的计算机访问服务器的权限和从服务器访问git服务器的权限分开（以获取最后的源代码）。您不需要从本地计算机上载源，而是通过服务器端的git请求部署。理论上，capistrano支持ssh代理，这样就可以使用本地密钥，而不需要在部署服务器上使用自己的密钥。事实上，这是理想的情况。然而，capistrano似乎在这一特性上有点破绽
