通過SSH連接到使用Capistrano的Bitbucket時出錯

Question

我是初學者，Rails,Git和Capistrano試圖部署我的第一個應用程序。

我已經安裝了一個VPS，安裝了Ubuntu,Nginx和Unicorn，現在想用Capistrano進行部署。我的應用存儲在Bitbucket存儲庫中。

爲了檢查我是否正確設置Capistrano我運行了以下命令。

$ cap production git:check和 $ cap production deploy:check

然而這些，給了我以下錯誤：

好像不順心的事與SSH認證，標準Git命令爲push或pull我的混帳存儲庫工作正常。

格羅姆我的本地機器$ ssh -T git@bitbucket.com告訴我：

Warning: Permanently added the RSA host key for IP address '104.192.143.7' to the list of known hosts. 
logged in as [USER]. 
You can use git or hg to connect to Bitbucket. Shell access is disabled. 

從我developer@vps帳戶：ssh -T git@bitbucket.com

Warning: Permanently added the RSA host key for IP address '104.192.143.7' to the list of known hosts. 
Permission denied (publickey). 

任何想法的？

Capistrano試圖在部署目標處檢出git存儲庫，即在VPS。因此，您需要獲得從VPS機器上的bitbucket的ssh連接。

我想你的ssh身份在你的本地主機和VPS上是不同的，而且你只配置了本地機器的ssh密鑰在bitbucket中。

您可以在您的本地機器上比較~/.ssh/id_rsa.pub，並在您的VPS上登錄爲developer？如果密鑰不同，則需要將VPS中的公用ssh密鑰（id_rsa.pub文件）添加到bitbucket配置，以便您可以使用ssh從VPS連接到bitbucket。
