Capistrano销毁ssh公钥授权

我遇到了一个问题，在我使用Capistrano部署到的两个不同服务器上，我遇到了两个不同的ssh用户，我对此感到非常困惑。我相信我不是唯一一个遇到这种情况的人：

我使用远程服务器已知的公钥，通过无密码身份验证从命令行设置ssh连接。这样做有效：我可以登录到远程系统

我执行»cap部署：设置«。令人惊讶的是，我必须输入ssh用户的密码，然后每次通过ssh在命令行上登录服务器时，我都必须再次输入密码。不再接受公钥，如ssh的-v选项生成的输出所示：

_

它可以在远程端无密码地拉取git存储库

如何防止Capistrano筛选SSH设置并再次使用公钥身份验证

非常感谢您的帮助

编辑：问题是服务器端：我刚刚发现我不能使用其他系统无密码登录到我的远程系统。我如何知道服务器出了什么问题？

显然cap已经破坏了服务器上的.ssh/authorized_密钥，无论是内容还是模式。authorized_密钥对所有人都是可读的，并且包含我的公钥。刚刚和系统管理员谈过。他说，他为SSH用户设置的监狱可能存在配置问题。所以我们可以先检查一下。无论如何谢谢你的帮助！如果.ssh目录和授权的_密钥文件是组或世界可读的，则ssh公钥登录将不起作用。
