使用Capistrano通过SSH连接Bitbucket时出错

Question

我是一个初学者，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，现在需要使用Capistrano进行部署。我的应用程序存储在Bitbucket存储库中。

为了检查是否正确设置了Capistrano，我运行了以下命令。

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

然而，这些错误给了我以下错误：

对于我的git存储库来说，SSH认证、标准git命令(如push或pull )似乎出了问题。

Grom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.

从我的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).

有什么想法吗？

Capistrano试图在部署目标(即VPS )上签出git存储库。因此，您需要从VPS机器获得到bitbucket的ssh连接。

我想您的ssh标识在本地主机和VPS上是不同的，并且您只在bitbucket中配置了本地机器ssh密钥。

您能比较一下本地机器上的~/.ssh/id_rsa.pub和VPS作为developer登录时的情况吗？如果密钥不同，则需要将VPS中的公共ssh密钥( id_rsa.pub文件)添加到bitbucket配置中，以便可以使用ssh从VPS连接到bitbucket。
