我有我的SSH密钥正确设置，我可以SSH密码进入远程机器。
然而，我的结构部署脚本，可以自动validation，直到几个小时前，每当我试图部署到远程机器开始问我的私钥密码。
即使我input密码，似乎也不在乎我是否给出了正确的密码，并提示系统login，就好像我根本没有ssh密钥。
请记住，我是一名开发人员，而不是系统工程师，他们不熟悉Fabric的工作原理。 我错过了一些明显的可能性相当高。 任何解决scheme，甚至指针的地方，将不胜感激。
这是我从真实部署脚本中获得的校对脚本：
#!/usr/bin/env python2 import sys from fabric.api import * from fabric.network import ssh ssh.util.log_to_file("paramiko.log", 10) @hosts(['host-ip-address']) def boot(): env.use_ssh_config = True env.user = 'userlogin' env.key_filename = ['~/.ssh/some-public-key.pem'] env.gateway = '[email protected]' execute(a) def a(): run('ls') boot() 这里是来自paramiko的日志消息：

我的~/.ssh/config
Host gateway HostName gateway.com User user Port 22 IdentityFile ~/.ssh/some-public-key.pem Host remote-machine HostName host-ip-address User userlogin IdentityFile ~/.ssh/remote-machine.pem ProxyCommand ssh gateway -W %h:%p
我想澄清，在我的本地机器上，我确实可以成功连接到远程机器，如下所示：
# ssh remote-machine
我发现这个问题。
如果我重新启动计算机，我必须重新添加所有密钥，即ssh-add <path/to/key.pem> 。
该线程解释了所需的configuration，因此您不必在每次重新启动计算机时重新添encryption钥。
