Will a RHEL/CentOS "yum update" have a negative impact on an existing Plesk installation?

[Bitpalast]

Plesk 12.5.30 #21 with Let's Encrypt extension

We want to update CentOS 7.2 to the latest libraries by "sudo yum update". The Update will update several libraries. Could Plesk be affected by such an update, e.g. because Plesk may have replaced some default CentOS vendor libraries by own libs?

Usually this painless but I suggest you create full backup of server just in case.

See http://www.webhostingtalk.com/showthread.php?t=1552794 for another user who ran into trouble.

While answering that thread I tried to find the formerly available "paid support" option for Plesk. It does not seem to be available any longer? We may need per-case support in the future. Where can we buy it when we need it?

Update: Sorry, just found it, here it is:

Ooops, no that's not the right page. That does not list Plesk as an option :-(

So where did the per-incident support go?

Forget about Odin. We are Plesk now. And our support is here https://cscontact.plesk.com/form/32/?Product=Plesk

Hello,

Don't update CentOS7 without a full backup.
I just updated a few days ago, and my server was down, your centos7 will not boot.
I saved and migrated all 80GB of data from the broken server with all devices mounted in rescue mode, cause there was a bug related with some drivers...
If u want to update the security patch of glibc, as shown here http://www.thegeekstuff.com/2016/02/glibc-patch-cve-2015-7547/, just run
yum -y update glibc.

Cheers

It does lead to a page where you have to enter a valid support contract ID or a licence that included support tickets. However, I was looking for the page where we could buy per-incident support. Entering the license key gives this message:

"It was identified that your Plesk license was purchased from one of the Plesk Partners. We strongly recommend that you request support from that provider. Plesk Partners are fully trained by Plesk and deliver best-in-the-industry support for Plesk products running on their infrastructure. You can use the product documentation (docs.plesk.com) and Knowledgebase (kb.plesk.com) to find a solution or ask a question on the Plesk Forum (talk.plesk.com). Plesk Partners should use their support codes to contact Plesk technical support team."

That is not what we'd like to get. We are willing to pay for the premium support, but obviously there is no option to do that any more.

And here is what another user says:

Plesk does not offer per incident support to users who have leased their licence from a Plesk partner.

 

[Bitpalast]

NO!!!, absolutely not

So it's not not safe, meaning it IS safe? Or are you saying that one should not "yum update", because it is unsafe? What are your experiences?

Hello,

Yum update broke my server.

Hi,

but not keeping your system up to date is also no option.
We have quite some CentOS 7 + PSA Containers and they have never had an issue with an "yum update".

I do agree that it is essential to have a backup. But you always need a backup, no matter what you do or don't do.
Even if you decide not to run "yum update", I'd still have a backup, because it is likely some security issue will occour
and your server might get compromised.

Kristian
