How to install CentOS 7 on 1&1 virtual server?

[Tomas_Kulikauskas]

Hello,

I want to update CentOS from:

Version     Parallels Plesk v12.0.18_build1200140606.15 os_CentOS 6
OS     CentOS 6.6 (Final)

to CentOS 7.

What steps I need to do to install CentOS 7?

Hello,

I don't believe Plesk supports full OS upgrades. You're probably better off migrating to a new CentOS7 server instead.

Kind regards,
Chris

Hi,

Plesk does not support OS upgrade CentOS6 -> CentOS7. (And as I know OS upgrade for CentOS itself is still in testing, not in "production ready" status)

You should use Transfer to new server. Setup new server with Plesk 12 & Centos 7 and use Plesk UI on new (destination) server to transfer.
Key notes are described here: http://kb.odin.com/en/121368

Additionally from Plesk Release Notes - http://download1.parallels.com/Ples....0-for-linux-installation-upgrade-info.html#1

Plesk does not support major OS upgrade (dist-upgrade).

CentOS 6 cannot be really upgraded to CentOS7 - it doesn't work even if no Plesk on board. CentOS 7 declared availability of OS upgrade at some point, but it didn't work.

You also probably cannot install new OS at virtual server.
Instead (as suggested above) you may need to request new server from 1&1 and move your Plesk there

If you want to have OS upgrades available, you need to switch Ubuntu/Debian. Next version of Plesk would support dist-upgrade on those OSes and even now dist-upgrade can work there with Plesk for a skilled administrator
