解释：
它不起作用是因为服务器需要密码进行身份验证，但是 ssh 由 Jenkins 执行，因此 ssh 的 stdin 连接到 Jenkins 而不是您的终端，所以 ssh 不可能要求输入密码。您需要配置服务器以接受基于 RSA 密钥的身份验证，这样您就可以向 ssh 提供密钥，以便能够在没有用户交互的情况下进行身份验证。
如何使用 RSA 密钥对进行身份验证：
- 在本地计算机上打开终端
- 执行
ssh-keygen -t rsa，对于位置只需按回车键，对于密码也只需按回车键。 - 执行（替换“
ssh-copy-id [email protected][电子邮件保护]“使用您的远程用户名和服务器 IP 地址） - 对于“确定要连接”的问题，请回答“是”。
- 输入您的服务器的密码。
- 现在您可以使用您的 RSA 密钥登录服务器。
