Google Compute Engine 重启后无法连接

2024-5-31 • tag-icon

由于过度使用，我不得不升级我的机器，这导致机器重启。之后我无法通过 PuTTY 连接，只能使用 Google 控制台。

另外，我的 SVN 存储库在那里，但我也无法连接到它。

我查看了“VPC 网络”中的防火墙规则，它们在重启之前是相同的：

iptables -L 的输出：

我的 ssh 密钥仍在，.ssh/authorized_keys但是当使用 PuTTY 时，甚至在询问用户之前，它就死机了：

Network error: connection timeout

当我尝试更新我的 SVN 本地副本时，它会死机“因为主机没有响应”。

我已经看过的内容：

这和这因为我使用 Google 控制台的访问非常顺畅，所以不要解决这个问题
两者都不这，因为这涉及到首次连接的问题

答案1

问题的原因是重启后 IP 发生变化。

我认为最好通知一下，除了重启之外，机器还可能遭受 IP 更改，除非你保留静态外部 IP。

幸运的是，这不是我的生产服务器，所以这种变化只是让我沮丧了几个小时，直到我发现了问题。
