的〜/ .ssh /配置

# User_A
Host github.com-User_A
HostName github.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes

# User_B
Host github.com-User_B
HostName github.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_user_b
IdentitiesOnly yes

# http://serverfault.com/questions/400633/capistrano-deploying-to-different-servers-with-different-authentication-methods
Host example.com
IdentityFile ~/.ssh_keys/example_env.pem
ForwardAgent yes

在本地计算机上:

  $ ssh -T git@github.com
  Hi User_B! You've successfully authenticated, but GitHub does not provide shell access.

在远程计算机上

    ~$ ssh remote_user@example.com

    [remote_user@example ~]$ ssh -T git@github.com
    Hi User_A! You've successfully authenticated, but GitHub does not provide shell access.

注意:

  • ssh-add -l显示所有提到的密钥
  • deploy.rb包含:

     set :repository,  "git@User_B:<REPO_NAME>"
    
     ssh_options[:forward_agent] = true
    

我正在尝试使用Capistrano将我的应用程序部署到Amazon EC2实例,我已经使用ssh-add将.pem文件添加到我的本地计算机,并且可以看到 ssh-add的输出中已登记-l 。但是在部署时我遇到了以下错误:

** [example.com :: err] ERROR: Repository not found.
** fatal: The remote end hung up unexpectedly

以下是我的cap deploy命令的完整输出:

$ cap bat deploy

所以我猜这个错误是由于多个SSH密钥被检测到之间的冲突引起的,即在本地机器上User_B(谁是存储库的成员)被用作默认设置但是在远程机器User_A(无法访问使用存储库。

如果我的假设是正确的,有人可以帮助我解决这个问题吗?有没有什么方法可以在代理转发时使用特定的用户配置?如果不是那么可能是什么解决方案?

感谢。

好吧,似乎〜/ .ssh / config中列出键的顺序很重要。

最初是

    # User_A
    Host github.com-User_A
    HostName github.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa
    IdentitiesOnly yes

    # User_B
    Host github.com-User_B
    HostName github.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_user_b
    IdentitiesOnly yes

    # http://serverfault.com/questions/400633/capistrano-deploying-to-different-servers-with-different-authentication-methods
    Host example.com
    IdentityFile ~/.ssh_keys/example_env.pem
    ForwardAgent yes

之后我做了这个:

    # User_B
    Host github.com-User_B
    HostName github.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_user_b
    IdentitiesOnly yes

    # User_A
    Host github.com-User_A
    HostName github.com
    User git
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa
    IdentitiesOnly yes


    # http://serverfault.com/questions/400633/capistrano-deploying-to-different-servers-with-different-authentication-methods
    Host example.com
    IdentityFile ~/.ssh_keys/example_env.pem
    ForwardAgent yes

但在这之后我没有重新启动机器,因此更改没有生效。

今天早上我在发布上述问题后启动机器后发现它正在运行:

在本地计算机上:

  $ ssh -T git@github.com
  Hi User_B! You've successfully authenticated, but GitHub does not provide shell access.

在远程计算机上

  $ ssh -T git@github.com
  Hi User_B! You've successfully authenticated, but GitHub does not provide shell access.

希望这有助于其他人,以防他面临类似的问题。

感谢。
