如何用另一个root ebs卷替换root ebs卷? [英] How to replace root ebs volume with another root ebs volume?

问题描述

我不小心格式化了系统，并且ec2卷的访问密钥也被删除了.因此，我停止了实例并分离了ebs卷.
但是我无法将它作为root(/dev/sda1)附加到另一个ec2实例.任何人都可以指导我完成它吗?我所有的数据和服务器文件都在该卷中.
我安装了第一个ebs卷，并在第二个实例上浏览了其中的文件.它们都完好无损.如果无法将其作为根卷挂载，则我需要一种从该卷中获取所有mysql数据的方法，因为其中托管了许多wordpress网站.我可以访问wordpress文件，但我不知道如何从实例中获取数据库.
任何解决方案都可以挽救我的生命... 非常感谢

I accidentally formatted my system and the access keys to the ec2 volume were also deleted. So I stopped the instance and detached the ebs volume.
However I am not able to attach it to another ec2 instance as root(/dev/sda1). Can anyone please guide me through it? All my data and server files are there in the volume.
I mounted the first ebs volume and on the 2nd instance and browsed the files in there. They are all intact. If it cannot be mounted on as root volume, I need a way to get all the mysql data from the volume as there are a number of wordpress websites hosted on it. I can access the wordpress files but I dont know how to get the database from the instance.
Any of the solutions will save my life... Thank you very much

推荐答案

您需要做什么:

1. 停止实例
2. 分离当前的根EBS
3. 在/dev/sda1(对于Linux)和/dev/xvda(对于Windows)下为您添加新的EBS
4. 启动实例

1. Stop the instance
2. Detach the current root EBS
3. Attach you new EBS under /dev/sda1 (for Linux) and /dev/xvda (for Windows)
4. Start your instance

从技术上讲就是这样.如果出现问题，您始终可以将EBS附加为非根目录的EBS(例如/dev/sdb)并浏览文件并在可能的情况下修复错误.

Technically that's it. In case of problems, you can always attach the EBS as non-rooted EBS (such as /dev/sdb) and browse the files and fix the error if possible.
