Question

我的GCP VM实例有时已设置好，所有服务均正常运行。但是，从今天起我突然无法通过SSH登录，甚至实例重启也无法解决问题。检查串行日志后，似乎已在此行中停止

启动SSH和其他服务不会进一步进行，因此我无法登录到实例。任何帮助将不胜感激。

谢谢。

错误

无包C状态可用

您是否尝试遵循此other post中编写的步骤？

看到 Ctrl + D 时，请输入root密码。然后输入with s(id, dt) as ( select 1, to_date('05/04/2019', 'dd/mm/yyyy') from dual union all select 1, to_date('05/10/2019', 'dd/mm/yyyy') from dual union all select 1, null from dual union all select 2, to_date('05/04/2019', 'dd/mm/yyyy') from dual union all select 2, to_date('05/10/2019', 'dd/mm/yyyy') from dual) select id, decode(count(dt), count(*), max(dt)) max_dt from s group by id; ID MAX_DT ---------- ----------------------------- 1 2 2019-10-05 00:00:00来查看错误所在的行。

输入mount -a并更正丢失的内容，保存并重新启动。

Answer 2

您可以做的是登录serial console，以便您可以与之交互。它可能会要求您提供root密码，如果尚未设置该密码，则可以通过startup scripts进行设置。
