amazon-web-services - will an on demand ec2 instance with root device ebs restart normally?

Question

I'm new to AWS. I have a Maverick Ubuntu installed on demand instance with root device EBS. I have a Mysql database running. Now ubuntu displays I should restart for new updates to be installed.

1. If I restart the system will it restart using root device EBS? Will there be any configuration or data losses?
2. Which way should I backup the system?

Thanks a lot!

Answer 1

不，由于您使用的是 EBS，因此不会有任何损失。要备份文件系统，您应该关闭 mysql，刷新文件系统，或者如果您使用支持它的文件系统，请使用 xfs_freeze 将其静默。

这个问题不太适合 SO，所以我希望它能够迁移到 Server Fault，这是搜索类似问题的好地方。
