Capistrano和几个SSH密钥

Question

我需要Capistrano使用2个不同的SSH密钥.一个用于git存储库,一个用于服务器部署到.

无论我在.ssh文件夹中重命名为id_rsa的哪个键都有效.另一个没有.如果我将git键重命名为id_rsa,Capistrano可以连接到git存储库,但是无法在服务器上进行身份验证以进行部署.如果我称之为其他东西,它将无法连接到git repo.我知道其他密钥有效,因为我可以执行ssh -i~/.ssh/otherKey.pem并且它将成功连接到服务器.

这就是我在deploy.rb Capistrano文件中的内容.

ssh_options[:keys] = [
        File.join(ENV["HOME"], ".ssh", "id_rsa"),
        File.join(ENV["HOME"], ".ssh", "deploy")
    ]

ssh_options[:forward_agent] = true 

我如何告诉Capistrano使用钥匙？它似乎只使用名为id_rsa的那个.

这是Capistrano的输出,错误信息如下:

另一件事:它完全可以从我的本地机器上运行,而不是在部署服务器上 - 具有完全相同的配置文件!似乎Capistrano在我的本地机器上使用了正确的密钥,但在部署机器上却没有.

Answer 1

免责声明:我对Capistrano一无所知.

如果它只是执行正常ssh调用(或调用git此操作),则可以~/.ssh/config在每个主机(或每个主机别名)的基础上配置正确的密钥.

例如,我在我的~/.ssh/config文件中有这些行:

# Git bei Github
Host github.com
User git
IdentityFile ~/.ssh/svn_id_rsa

#  Andere Mathe-Hosts
Host *.math.hu-berlin.de
User ebermann
IdentityFile ~/.ssh/id_rsa
ControlMaster auto

Answer 2

我在deploy.rb中有这一行:

ssh_options[:keys] = %w(/Users/victor.pudeyev/ec2/MBP-2.pem)

这表明密钥文件名是空格分隔的,例如

ssh_options[:keys] = %w(/Users/victor.pudeyev/ec2/MBP-1.pem /Users/victor.pudeyev/ec2/MBP-2.pem)
