Upgrade Enterprise Linux c версии 7 на версию 8 с сохранением данных

Давно уже наступил срок End of Life у Enterprise Linux 7, но возможно на ваших серверах он еще есть в работе. Затягивание процесса переноса могло произойти по разным причинам: сложные процессы миграции, необходимость в дополнительных мощностях для маневра, длительность процесса переноса, зависимость от бизнес-процессов заказчиков. Зачастую upgrade ОС на месте — самый удобный способ. В данной статье я описываю инструменты и трудности, с которыми вы можете столкнуться в процессе.

Red Hat are detecting that a few of the default ciphers in the crypto-policies package they supplied in RHEL8 are now considered insecure.

Hopefully someone at Red Hat will see sense and update the crypto-policies to remove the insecure defaults.

This is on a RHEL 8.10 updated system.

Does anyone here use brp_mangle_shebangs for #rhel8 rpm spec files? I am lost why my shebang excludes is not working 😐

Any help on syntax would be appreciated

#OpenELA Publishes Initial Source Code For Building #RHEL Derivatives
#CIQ (#RockyLinux), #SUSE, and #Oracle decided to form the Open Enterprise #Linux association (OpenELA) to collaborate around the development of distributions with compatibility against #RedHat Enterprise Linux and ensuring open and free access to EL source code. Today they are announcing initial #sourcecode available for their #RHEL8 and #RHEL9

The constant battle to keep #RHEL8 working in a production environment this last years has taken its toll.

I wish I could convince the powers that be to switch to #SUSE.

Check the size of DH keys during a #TLS handshake (it just helped me to diagnose a connection refusal from curl on a #RHEL8 server) via @feistyduck https://www.feistyduck.com/library/openssl-cookbook/online/testing-with-openssl/determining-the-strength-of-dh-parameters.html

We are currently using #NFS for storage on our #k8s cluster. We are testing #OpenEBS now.

Because you mentioned many issues with #OpenEBS and none with #Longhorn , I think we need to take another look at #Longhorn and #Rancher.

Currently using #RHEL8

@tero

My day has consisted of storage increases and RHEL buildouts for customers.

#linux #rhel #rhel8

I'm thinking I need a pull through cache for my home #kubernetes cluster, to speed up any restarts/redeployments of apps across the cluster. I'm using #rhel8 and #podman

Does anyone have any suggestions? In cluster would be nice, but not critical. Leaning towards just JFrog CR just because of using Artifactory in the past.

<< hey Lucifargundam, could you fix the vnc on the #rhel8 systems?

The stable release of #AlmaLinux OS 8.3 "Purple Manul", based on Red Hat Enterprise Linux, is officially available!

AlmaLinux OS is an open-source, community-driven project that intends to fill the gap left by the demise of the CentOS stable release. AlmaLinux OS is a 1:1 binary compatible fork of RHEL® 8.

A migration script for #RHEL8, #CentOS8 and #OL8 is provided as well.

I’m looking into learning RHEL to try and get a position providing support for it in an enterprise with ~7,000 employees. If anybody has any tips on learning material, specific subjects I should learn, or if you think it’s a waste of my time, then please let me know. #rhel8 #rhel #linux

"For those relying on CentOS 8 to enjoy the reliability and features of Red Hat Enterprise Linux 8 but without the licensing costs, etc, that will end in 2021. "

So that's how #IBM thinks it'll make even more business with #GNU/#Linux.

I'm testing #CentOS #Stream and it is actually quite cool. But killing of the 1:1 rebuild from #RHEL8 sources is a mistake IMHO. A big mistake - at least if #RedHat won't provide a much more open access to the original #RHEL itself.

So have your playbooks by hand and get ready to deploy a whole load of new boxes :)

If you are waiting for CentOS 8 since RHEL 8 came out in May, you might be interested in why it's still not there:

https://www.montanalinux.org/wherefore-art-thou-centos-8-20190911.html

TL;DR: There was RHEL7.7 which becomes CentOS 7.7 and since CentOS already has tons of active users, it's more important to ship CentOS 7.7 than CentOS 8.
