Linode 开机出错

aaazzx · 发表于 2015-3-1 15:31:24

军哥遇过这情况吗

今天用putty用root登录主机，帐密都对，但一直显示 Permission denied
就到Linode后台改root密码，改完才发现要关机才能改，就关机改密码
开机之后就一直连不上去了
用后台的Remote Access去登录，就报下面的错误
这是什么情况
该怎么处理，数据都还没备份．．．

不清楚什么问题，你可以在linode后台上进入Rescue Mode模式挂载上硬盘对数据先进行备份，问问linode客服这是什么问题

下面是客服的回答,超出客服的能力範圍了...

You'll want to consult with your developer for this matter. If your developer is unavailable, I recommend you reach out to our community for further assistance as this is beyond the scope of support we can provide. Our community can be reached via one of the following avenues:

- Our forum at https://forum.linode.com
- IRC in #linode on irc.oftc.net

另一个客服有提供这篇
https://www.linode.com/docs/troubleshooting/rescue-and-rebuild
里面有挂载硬盘跟数据备份
还有提到chroot
chroot是做什么用的？能救回系统吗？
还是只能备份数据在重装系统呢？
目前有什么办法能让系统正常运行呢？

chroot和备份没关系，rescue挂载硬盘后就能看到你原来硬盘上的数据

没办法解决这个问题就只能备份数据，然后重装恢复数据

感谢军哥
看来只能重装系统在恢复数据了
