linode 老是要我重启怎么办?

[gancl]

服务器不是运行几年都不重启吗? linode 最近老是因为安全原因告诉我要重启,几乎两三个月重启一次. 一些服务程序没有做开机启动,之后我还要花很多时间精力维护:

** Upgrading your Linode to KVM will remove it from this maintenance. **

Hello,

Linode recently received several Xen Security Advisories (XSAs) that require us to perform updates to our host servers. In order to apply the updates, hosts and the Linodes running on them must be rebooted. The XSAs will be publicly released by the Xen project team on December 17th, therefore we must complete the updates before that date.

These updates are required to protect the security and safe operations of not only our infrastructure, but yours as well. We understand that a disruption with such limited notice is inconvenient, and we hope you understand that these measures are warranted due to the severity of the XSAs.

Your Linodes have been assigned a maintenance window in which a reboot will occur. These times are listed within the Linode Manager[1] in the timezone set in your user's My Profile[2]. Your schedule in UTC timezone is as follows:

• 2015-12-14 5:00:00 PM UTC - linode522821

During the maintenance window Linode instances will be cleanly shut down while we perform the updates. Your Linode will be inaccessible during this time. A two-hour window is allocated, however the actual downtime can be much less. After the maintenance, each Linode will then be booted.

It is highly recommended that you ensure that services are set to properly start after a reboot before your maintenance window. You can consult our Reboot Survival guide[3] for more information on how to do this. After going through that guide, it is recommended to reboot your Linode at a convenient time to ensure your services come up correctly.

As previously mentioned, you can upgrade your Linode to KVM prior to your maintenance window to avoid the maintenance all together [4].

Please note that due to the logistical demands of this effort, your assigned windows are not changeable and the host reboots are mandatory.

For general information, please see our status post: http://status.linode.com/incidents/ngql6k6dm420

Please let us know if there is anything we can do to assist.

@gancl you can upgrade your Linode to KVM prior to your maintenance window to avoid the maintenance all together

升到到 KVM 就没那么多升级重启了。

[msg7086]

因为 Xen 有漏洞需要补。

你看，至少比漏洞不补结果机器被人黑了好吧？

[baishishi]

我也收到这个了，这是要让我们自己升级吗？

[msg7086]

@baishishi 不是，到点了他会给服务器打补丁然后重启所有的机器。

升级 KVM 可以避免频繁重启，然而日本节点目前都是 Xen 不能迁移为 KVM
