问题描述

我将OpsCenter从6.0.3升级到6.0.5。有没有办法迁移LCM数据?它与复制文件lcm.db一样简单吗?谢谢。

I upgraded OpsCenter from 6.0.3 to 6.0.5. Is there a way to migrate the LCM data? Is it as simple as copying the file lcm.db? Thanks.

推荐答案

OpsCenter开发人员在这里。 6.0.3到6.0.5是就地执行的安全升级。因此,如果是软件包,则可以 yum upgrade或 apt-get upgrade。

OpsCenter developer here. 6.0.3 to 6.0.5 is a safe upgrade to do "in-place". So if it's a package you can just 'yum upgrade' or 'apt-get upgrade'.

如果出于任何原因要备份/还原设置,则最好看的文档是我们的高可用性文档(HA故障转移基本上是备份/还原): https://docs.datastax.com/en/opscenter/6.0/opsc/configure/enableFailover.html https://docs.datastax .com / en / upgrade / doc / upgrade / opscenter / upgdOpsc.html

If you do want to backup/restore your settings for whatever reason, the best docs to look at are our high-availability docs (HA failover is basically a backup/restore): https://docs.datastax.com/en/opscenter/6.0/opsc/configure/enableFailover.html. The upgrade docs may also be useful https://docs.datastax.com/en/upgrade/doc/upgrade/opscenter/upgdOpsc.html.

LCM的TLDR(不在我头上)是:

The TLDR for LCM (off the top of my head) is:


  • lcm.db

  • ssl目录(如果您具有节点到节点或启用了客户端到节点(这是LCM证书颁发机构所在的位置,如果无法还原此证书,则在以后无法为它们颁发兼容证书时,将很难添加节点。)

  • 密钥目录中的db加密密钥(如果无法还原,则将无法访问已加密的数据库字段,例如ssh-credentials的密码或ssh-private-key)。
