当我在CentOS上使用capistrano'限制生产部署'时，我会遇到以下错误。
我确信我的git和服务器的pirvate密钥都是完美的原始文件，公钥通常在服务器上。
我有 ssh_options [：keys] = [File.join（ENV [“HOME”]，“。ssh”，“example-rsa”）] 在我的production.rb中，我正确地将文件作为/root/.ssh/example-rsa。 我 ssh-add ed我的git和服务器的私钥。
奇怪的是，即使两个文件都需要密码短语，我的终端也要求我输入git的密码，但不是服务器的密码。
我用服务器，opeenssh等同步了我的ruby版本。

通过删除newline中ssh-rsa之后的$HOME/.ssh/id_rsa.pub字符解决问题。
如果您使用其他公钥文件，请更改该文件。
答案 1 :(得分：0)
我的问题是我的本地~/.ssh/known_hosts文件中有很多不同的密钥，因为每次我的VPS在救援模式下重新启动它都会改变。
所以我删除了所有这些并正常连接到ssh（而不是通过capistrano），然后我尝试使用capistrano并且它有效。
其他详细信息：当ssh无法读取密钥文件时，会发生这种情况，您可以运行ssh -v user@host来查看正在进行的操作
（请参阅第一个答案中的评论：https://serverfault.com/questions/613756/how-to-stop-ssh-passphrase-prompt）
答案 2 :(得分：0)
就我而言，我得到
cap aborted!
Z?.?.D??'entedError: unsupported key type `??c=M?#HF?:??
当我尝试使用capistrano在puma服务器上重启prod时：
bundle exec cap production puma:restart --trace
这是一个非常奇怪的问题，我花了几分钟时间才找到要解决的问题...我想检查哪个文件失败，capistrano将运行常规的ssh命令，而我我可以肯定地说，我可以ssh服务器正常运行，我确认：
ssh -v -i my_key.pem ec2-user@6.66.666.666我能够做到。
在我看来，一切似乎都net-ssh并未解析其中一个文件，这就是我查找多少文件以及可以使用哪些文件的方法。
使用：
ls ~/.ssh
我看到了所有这些
my_key.pem config id_rsa id_rsa.pub known_hosts
我不得不逐个重命名每个文件，以查找将导致不同错误的文件，直到发现其他错误消息我才这么做：
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as
....
Authentication failed for user
....
**这是known_hosts **文件!!!由于此文件是自动生成的，因此我仅创建了一个备份（mv ~/.ssh/known_hosts ~/.ssh/known_hosts.BAK）并继续前进！ :)终于能够重新启动产品的服务器puma流程，这使Web应用程序可以像以前一样运行（AWS EC2实例出现问题，因此必须重新启动该框）
