通过SSH连接到使用Capistrano的Bitbucket时出错

Question

我是初学者，Rails,Git和Capistrano试图部署我的第一个应用程序。

我已经安装了一个VPS，安装了Ubuntu,Nginx和Unicorn，现在想用Capistrano进行部署。我的应用存储在Bitbucket存储库中。

为了检查我是否正确设置Capistrano我运行了以下命令。

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

然而这些，给了我以下错误：

好像不顺心的事与SSH认证，标准Git命令为push或pull我的混帐存储库工作正常。

格罗姆我的本地机器$ ssh -T git@bitbucket.com告诉我：

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. 

从我developer@vps帐户：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试图在部署目标处检出git存储库，即在VPS。因此，您需要获得从VPS机器上的bitbucket的ssh连接。

我想你的ssh身份在你的本地主机和VPS上是不同的，而且你只配置了本地机器的ssh密钥在bitbucket中。

您可以在您的本地机器上比较~/.ssh/id_rsa.pub，并在您的VPS上登录为developer？如果密钥不同，则需要将VPS中的公用ssh密钥（id_rsa.pub文件）添加到bitbucket配置，以便您可以使用ssh从VPS连接到bitbucket。
