CentOS 7 existing system after June 2024

Post by Oso » 2023/05/30 21:29:20

With the obvious exception of software updates, are there any services essential to the running of CentOS 7 that will be withdrawn and which might prevent an existing CentOS server from continuing to run?

Are repositories available, in the event of needing to reinstall — for example — VirtualBox?

To be clear, my hardware will be close to its anticipated replacement, but not quite. Thanks.

You can find old versions in https://vault.centos.org/ (or in the mirrors).
I did run CentOS 5 a bit after updates ran out and I cannot remember any problems. YMMV

Repositories will get moved to vault.centos.org. They would not be needed to install VBox anyway.

But you are still going to be left with a system that will get no more fixes which may be fine... right up until it isn't and there's a major security vulnerability that will never get fixed.

Be sensible, migrate to something newer in advance.
The future appears to be RHEL or Debian. I think I'm going Debian.

Thanks for the replies. If I migrate to one of the CentOS alternatives, for instance Rocky etc., will any of the following apply, or would I need to install another way? Thanks in advance.

https://www.virtualbox.org/wiki/Linux_Downloads
VirtualBox 7.0.8 for Linux :

​Oracle Linux 9 / Red Hat Enterprise Linux 9
​Oracle Linux 8 / Red Hat Enterprise Linux 8
​Oracle Linux 7 / Red Hat Enterprise Linux 7 / CentOS 7
​Ubuntu 22.04
​Ubuntu 20.04
​Ubuntu 18.04 / 18.10 / 19.04
​Debian 11
​Debian 10
​openSUSE 15.3 / 15.4
​Fedora 36
​Fedora 35
​All distributions (built on EL6 and therefore not requiring recent system libraries)

If something works in Oracle Linux Y and RHEL Y, then it should be fine in AlmaLinux Y and Rocky Linux Y too.

"If something works in Oracle Linux Y and RHEL Y, then it should be fine in AlmaLinux Y and Rocky Linux Y too."

Thanks for the help, starting the process now. It's a wrench to move away from CentOS, as my system has been running mostly without a problem since 2014. I reinstalled it with 7.3.1611 in late-December 2016 and as far as I can recall, hasn't been updated since then. I just use it on a personal network, start it up each morning, shut it down at night. :)

If you are a forum fan, both distributions have their own forum: AlmaLinux and Rocky Linux.

I began looking at Alma Linux, inside VirtualBox, so I could evaluate it first, but unfortunately it requires x86-64-v2. Things are rarely straightforward :(

I did some research. It seems that Redhat has moved to a new CPU instruction set, requiring this. To be honest, it would be much simpler and less of a headache for me to stick with CentOS 7 until the system reaches end-of-life. That was my original plan. It's a pity though, as I was looking forward to moving the system forward, but I can't spend time when there's other work to be done.

Actually, I don't like Redhat's commercial practices vis-à-vis the below, where the simple background to a fairly widespread problem is obscured without subscribing to their services. Personally I think it's going to be a "goodbye anything-to-do-with-Redhat".

Yes, the RHEL 9 (and its clones) do require the CPU to support the instructions defined by "x86-64-v2" spec: https://developers.redhat.com/blog/2021 ... ture-level
The glibc in RHEL 8 can show what specs the CPU support, but lacking that one can look at /proc/cpuinfo: https://unix.stackexchange.com/question ... -x86-64-v2

(Most) Intel CPU's from around 2010 (and AMD a bit later) do support the x86-64-v2.
If your hardware is too old, then you can still install RHEL 8 (and its clones).

If your hardware does support x86-64-v2, then you have to set VirtualBox to pass those features to VM, where you test el9 distro.


Red Hat is quite clear about what RHEL 9 requires. Much more clear and less demanding than what I've seen said about Windows 11.
