包含多個SSH密鑰Capistrano的部署Github的SSH配置失敗，沒有找到話說庫

Question

的〜/ .ssh/config中

# 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 

在本地機器上：

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

在遠程機器

~$ 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. 

備註：

• SSH-添加-l顯示所有提到的鍵入伍

• deploy.rb包含：

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

我試圖部署使用Capistrano的到Amazon EC2實例我有關申請我已經使用ssh-add將.pem文件添加到本地計算機上，並且可以看到輸入爲ssh-add -l。但是，在部署時遇到以下錯誤：

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

以下是我的帽子部署命令的完整輸出：

$ cap bat deploy

    triggering start callbacks for `deploy'

    servers: ["example.com"] 
    [example.com] executing command

    servers: ["example.com"]

    command finished in 477ms 
    failed: "sh -c 'if [ -d /srv/<APP_NAME>/shared/cached-copy ]; then cd /srv/<APP_NAME>/shared/cached-copy && git fetch -q origin && git fetch --tags -q origin && git reset -q --hard df84fadff305e1729991caddde47f6802e424d57 && git clean -q -d -x -f; else git clone -q git@User_B:<REPO_NAME> /srv/<APP_NAME>/shared/cached-copy && cd /srv/<APP_NAME>/shared/cached-copy && git checkout -q -b deploy df84fadff305e1729991caddde47f6802e424d57; fi'" on example.com 

所以我想這個錯誤是由於多個SSH密鑰之間發生衝突造成越來越本地機器USER_B（即檢測出誰是成員）作爲默認值使用，但在遠程計算機上使用User_A（無權訪問存儲庫）。

如果我的假設是正確的，任何人都可以幫助我解決這個問題嗎？代理轉發時可以使用特定用戶配置嗎？如果不是，那麼解決方案是什麼？

謝謝。

好吧，好像它在〜/ .ssh/config中列出鍵的順序很重要。

最初，它是

# 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 

後來我這樣做：

# 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 

但這樣做，我沒有重新啓動機器後，因此變化並不生效。

今天上午後，我開始我的機器上張貼上述問題，我發現，這是工作後：

在本地機器上：

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

在遠程機器

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

希望這有助於別人也會遇到類似的問題。

謝謝。
