Friday evening + homelab VM + bad ideas = RHEL 9.7 on ZFS root.

I patched convert2rhel until it stopped saying no.

The Best Boring #Benchmarks: #RockyLinux10 & #AlmaLinux10 Performance Against #RHEL10 Review
Testing on an AMD EPYC 9755 2P (EPYC Turin) server and using the same hardware across all tests, the performance of #RockyLinux 10 and #AlmaLinux 10 were right on-par with #RedHat #EnterpriseLinux 10 itself. Hence the best kind of boring benchmarks when the performance is right on track for where it should be.

#RHEL #Linux

As #RHEL clones hit version 10, Rocky and Alma chart diverging paths
Take a quick look at the headline features – and the growing differences
Perhaps the biggest and most obvious technological difference in this version is that #AlmaLinux offers a separate version for x86-64-v2 hardware. #RHEL10 itself, and Rocky with it, now require x86-64-v3, meaning Intel "Haswell"
But you'd expect all the RHELatives to be similar. That remains their primary selling point.

#RockyLinux 10.0 has been released (#RockyEnterpriseSoftwareFoundation / #RESF / #CIQ / #OpenEnterpriseLinuxAssociation / #OpenELA / #RedHat / #EnterpriseLinux / #RHEL / #RedHatEnterpriseLinux / #IBM / #CentOS / #Fedora / #Linux) https://rockylinux.org/

Rocky Linux 10, based on RHEL 10, released

Following the release of the Red Hat Enterprise Linux 10 and the AlmaLinux 10, yet another Red Hat-based Linux derivative distro, Rocky Linux, has just released a new version that is compatible with the tenth major version of RHEL. This sets a huge milestone for just another community version of the RHEL distribution. You can download this version of Rocky Linux here.

Rocky Linux 10, just like RHEL 10, requires the x86_64-v3 processor in order to run on modern computers. This is unlike AlmaLinux 10 that needed at least the x86_64-v2 processor. Also, Rocky Linux 10 no longer ships the 32-bit packages, which means that you will no longer to run 32-bit applications.

For the desktop environment, this version of Rocky Linux now uses the Wayland server exclusively instead of the legacy X11 protocol. However, some of the applications that have not yet been ported to Wayland can now run using the Xwayland protocol.

This version of Rocky Linux now supports the RISC-V architecture for users with such processor architecture. This is to make sure that computers that use a RISC-V processor be able to use Rocky Linux for the first time, expanding hardware support to the broader audience.

The following architectures are supported:

• 64-bit AMD/Intel x86-64-v3 (x86_64)
• 64-bit RISC-V (riscv64)
• 64-bit ARMv8.0-A (aarch64)
• IBM POWER, little endian (ppc64le)
• IBM z (s390x)

The following common packages have been updated:

• Dynamic programming languages, web, and database servers
  • PHP 8.3
  • Python 3.12
  • nginx 1.26
  • PostgreSQL 16.8
  • MySQL 8.4
  • Valkey 8.0
  • MariaDB 10.11
• Performance tools and debuggers
  • GDB 14.2
  • Valgrind 3.23.0
  • SystemTap 5.1
  • Dyninst 12.3.0
  • elfutils 0.192
  • libabigail 2.6
• Performance monitoring tools
  • Performance Co-pilot 6.3.0
  • Grafana 10.2.6
• Compiler toolsets
  • LLVM Toolset 19.1.7
  • Rust Toolset 1.84.1
  • Go Toolset 1.23

Running the cloud server for my website and my Forgejo instance on Red Hat Enterprise Linux (RHEL) 10 :redhat: now.

(Previously on CentOS-Stream9 :centos:)

Since I only have little load and want my infrastructure to consume as little energy as possible, I am running on an ARM64 (aarch64) system with Altara Ampere (Neoverse-N1) CPUs and on a shared hypervisor (Qemu/Kvm).

RHEL10 does run perfectly fine and is supported on the ARM64 CPU architecure :-)

All applications (my website, Forgejo, and a Keycloak instance) are running as rootless containers with Podman :podman:

And of course, all my services are run IPv6 first!

#linux #selfhosting #server #redhat #centos #rhel #rhel10 #devops #ipv6 #forgejo

Just migrated my Cloud-Server at Netcup from CentOS-Stream 9 :centos: to Red Hat Enterprise Linux (RHEL) 10 :redhat:

Since all my workloads were containerized with Podman :podman: that was very simple to do:

- Deploying new server in parallel
- Stopping all containers
- Moving the volumes and the systemd/quadlet files over to the new machine (/etc/containers/systemd)
- Starting all containers on the new host
- Updating DNS entries to new IP addresses
- Decomissioning the old machine

It seems Red Hat Enterprise Linux 10 has been released. But what is new? The "release notes" ramble about "AI" and PQC, but... where are the actual release notes?!

Эффективная защита Linux: использование Ansible для соблюдения рекомендаций ФСТЭК России

25 декабря 2022 года ФСТЭК России выпустила рекомендации по безопасной настройке операционных систем Linux. Сейчас эти рекомендации являются обязательными для государственных информационных систем и критической информационной инфраструктуры (КИИ), работающих на Linux. Для упрощения соблюдения этих рекомендаций и автоматизации настройки систем можно использовать Ansible. Этот инструмент позволяет массово развертывать конфигурации, что значительно снижает вероятность ошибок при ручном вводе. В статье рассмотрим готовые плейбуки на основе Ansible для RHEL-подобных систем, а также способы их адаптации для других ОС.

#RockyLinux 9.5 has been released (#RockyEnterpriseSoftwareFoundation / #RESF / #CIQ / #OpenEnterpriseLinuxAssociation / #OpenELA / #RedHat / #EnterpriseLinux / #RHEL / #RedHatEnterpriseLinux / #IBM / #CentOS / #Fedora / #Linux) https://rockylinux.org/

I've just merged a huge PR to my #Orked (O-tomated RKE Distribution - GREAT NAME I KNOW) that makes it easier than ever for anyone to set up a production-ready #RKE2 #Kubernetes cluster in their #homelab.

With this collection of scripts, all you need to do is just provision the nodes required, including a login/management node, and run the scripts right from the login node to configure all of the other nodes to make up the cluster. This setup includes:

- Configuring the Login node with any required or essential dependencies (such as #Helm, #Docker, #k9s, #kubens, #kubectx, etc.)

- Setup passwordless #SSH access from the Login node to the rest of the Kubernetes nodes

- Update the hosts file for strictly necessary name resolution on the Login node and between the Kubernetes nodes

- Necessary, best practice configurations for all of the Kubernetes nodes including networking configuration, disabling unnecessary services, disabling swap, loading required modules, etc.

- Installation and configuration of RKE2 on all the Kubernetes nodes and joining them together as a cluster

- Installation and configuration of #Longhorn storage, including formatting/configuring their virtual disks on the Worker nodes

- Deployment and configuration of #MetalLB as the cluster's load-balancer

- Deployment and configuration of #Ingress #NGINX as the ingress controller and reverse proxy for the cluster - this helps manage external access to the services in the cluster

- Setup and configuration of #cert-manager to obtain and renew #LetsEncrypt certs automatically - supports both #DNS and HTTP validation with #Cloudflare

- Installation and configuration of #csi-driver-smb which adds support for integrating your external SMB storage to the Kubernetes cluster

Besides these, there are also some other helper scripts to make certain related tasks easy such as a script to set a unique static IP address and hostname, and another to toggle #SELinux enforcement to on or off - should you need to turn it off (temporarily).

If you already have an existing RKE2 cluster, there's a step-by-step guide on how you could use it to easily configure and join additional nodes to your cluster if you're planning on expanding.

Orked currently expects and supports #RockyLinux 8+ (should also support any other #RHEL distros such as #AlmaLinux), but I am planning to improve the project over time by adding more #Linux distros, #IPv6 support, and possibly even #K3s for a more lightweight #RaspberryPi cluster for example.

I've used this exact setup to deploy and manage vital services to hundreds of unique clients/organisations that I've become obsessed with sharing it to everyone and making it easier to get started. If this is something that interests you, feel free to check it out!

If you're wondering what to deploy on a Kubernetes cluster - feel free to also check out my #mika helm chart repo 🥳

Decisions that didn't age well (oVirt dropping Fedora support to focus specifically on RHEL). Red Hat dropped general commercial support for oVirt (RHV) last year and has removed SPICE from #RHEL. #ovirt #Fedora #virtualization #libvirt #Linux

@carlwgeorge @jbouter This is what I do at $DAYJOB, where I'm implementing #CentOS #Stream for anything that won't use #RHEL or doesn't have annoying validation requirements on RHEL minor versions. Which means everything for now until we actually make the RHEL purchase 😅 Waiting on the final sign off from the higher ups on that...

Using tools like #Foreman+#Katello (upstream of #Satellite) to handle system and content lifecycles makes life stupid simple in ensuring matching environments.

AND WE CAN MAKE SUBSCRIPTION ALLOCATIONS NOW

For those that don't know what that means, it allows you to import your subscriptions directly into Foreman+Katello (Red Hat Satellite) rather than having to configure your own local mirror to do so.
