Question

我正在尝试使用fabric部署django应用程序并获取以下内容错误：

Alexs-MacBook:fabric alex$ fab config:instance=peergw deploy -H <ip> - 
u <username> -p <password> 

[192.168.2.93] run: cat /etc/issue

paramiko.SSHException: Invalid key 

Alexs-MacBook:fabric alex$

我无法通过ssh连接到服务器。什么可以成为我的问题？

此致，Arshavski Alexander。

Answer 1

在这里走出困境，我说你的SSH密钥不正确：

paramiko.SSHException：无效的密钥

当您尝试使用您提供给结构的用户名和密码时，服务器会说什么？

第二个想法：当您为Fabric提供密码时，可能会建议您的SSH主机密钥已更改和/或尚未添加到~/.ssh/known_hosts。

Answer 2

是的，我会说你要连接的机器上的主机密钥已经改变了。（或者您从一台从未通过“xxx是未知主机的机器连接，是否要将其添加到已知主机列表？”对话框。）

如果您不关心中间人攻击或者几天前自己更改了密钥，请在您的env.variables中的某处添加以下行：

env.disable_known_hosts = True

应该照顾它！
