ruby-on-rails - Rails : Capistrano. 权限被拒绝(公钥)

Question

我一直在寻找一种使用 capistrano 部署我的应用程序的方法。我目前在 github 和本地服务器上托管一个小型私有(private)仓库来尝试部署我的测试。我在下面遇到问题和错误消息。

我做了以下

在服务器上生成一个 ssh key 并成功添加它以在 repo 中部署 key 并测试(git@github.com)

在客户端生成 ssh key 并成功添加以在 repo

中部署 key

设置一个私有(private)存储库。并拥有拥有部署权限的帐户部署者

配置 deploy.rb 和 production rb 以模仿许多其他模板。

我仍然无法弄清楚为什么它会给我这样的错误

我有一个类似的问题。事实证明 SSH 代理没有运行。我在查看 Capistrano 文档时发现了这一点:http://capistranorb.com/documentation/getting-started/authentication-and-authorisation/

运行此命令:

$ ssh-add -l

显示我的公钥没有添加到代理中，所以我必须添加它:

$ ssh-add

添加的身份:/Users/me/.ssh/id_rsa (/Users/me/.ssh/id_rsa)

在此之后，我的 Capistrano 部署成功了。
