我让 Jenkins 在我的本地机器上运行，试图找出我在服务器上遇到的远程 ssh 问题。我收到此权限被拒绝错误，这表明密钥有问题，但从 shell 上的同一用户帐户，我绝对可以连接。

这是在 shell 上运行的：

Jasons-MacBook-Air:~ jgoodwin$ echo $HOME
/Users/jgoodwin
Jasons-MacBook-Air:~ jgoodwin$ whoami
jgoodwin
Jasons-MacBook-Air:~ jgoodwin$ ssh -i /Users/jgoodwin/.ssh/id_rsa remoteuser@server 'echo success'
success

我很困惑——过去我和哈德森一起做过很多工作，我认为我在做这类工作时没有任何问题。该错误表明密钥有问题，但它们显然很好。

多种原因可能导致此行为，例如使用代理/钥匙串管理器进行密钥缓存等。

我建议使用 -v 参数来比较 2 个输出：

ssh -v -i /Users/jgoodwin/.ssh/id_rsa remoteuser@server

这将使您以更详细的方式比较正在发生的事情。如果您仍然无法解决它，请发布您的详细输出以进行比较。

注意：您最多可以添加 3 个 -v 参数以增加详细程度。

更新：

@JasonG 从我看到的失败细节是：

debug1：提供 RSA 公钥：/Users/jgoodwin/.ssh/id_rsa debug1：服务器接受密钥：pkalg ssh-rsa blen 279 debug1：key_parse_private_pem：PEM_read_PrivateKey 失败 debug1：读取 PEM 私钥完成：键入 debug1：read_passphrase：不能打开 /dev/tty：设备未配置

看起来您的密钥有一个密码，并且无法输入密码，因为我们不在交互式 shell 中。您的标准 shell 中的命令行可能会受益于 Keycahin，它会为您“输入密码”。

如果您可以为成功的命令生成相同的详细程度，以便我们可以比较......

Jenkins 运行 shell 脚本与环境中的 cmd 行略有不同

您的情况存在一些环境差异，我们没有注意到。像初始脚本，路径设置。

除了@coffeebreaks提供的方法，试试下面

  • 检查系统环境，如 show 命令env
  • 将上述步骤写入 bash 脚本并在 cmd 行和 jenkins 作业中运行脚本
  • 使用另一个用户而不是启动 jenkins 实例的初始用户

看起来 /Users/jgoodwin/.ssh/id_rsa.pub 下缺少公钥，而不是 id_rsa 那里....您能否仔细检查并为该文件提供权限 600 并重新运行您的詹金斯作业

在我的情况下，我使用的是一个钥匙串（正如@coffeebreaks 建议的那样），当我在 jenkins 用户 .bashrc 文件中获取时正在设置它。不幸的是，jenkins 后端似乎不像标准 shell 登录那样获取这个文件。

解决方案是在 Jenkins 管道中的 scp 调用之前添加以下代码：

. ~/.bashrc
