  • Managing and automating kernel settings with RHEL System Roles

    The Red Hat Enterprise Linux (RHEL) kernel provides hundreds of settings that can be customized. These settings are frequently customized to increase performance on systems or when performing security hardening.

    Implementing consistent kernel settings across a large RHEL environment can be challenging without automation. Red Hat introduced the kernel_settings RHEL System Role to automate the implementation of settings under /proc/sys, /sys, and other settings such as CPU affinity. The role uses tuned to implement these settings on hosts.

    RHEL System Roles are a collection of Ansible roles and modules that are included in RHEL to help provide consistent workflows and streamline the execution of manual tasks. For more information on kernel settings in RHEL, refer to the RHEL documentation on Managing, monitoring, and updating the kernel.

  • Stefanie Chiras to lead Red Hat global partner ecosystem [Ed: It says “leading Red Hat partners such as Microsoft”]

    I got involved in the Linux space while at IBM as part of the Power Systems team, and since then I've remained fascinated by the immense value that Linux brings to the industry. Linux really has taught us how development is meant to be done, through open source and the heart of innovation unifying a community. I joined Red Hat in order to lead the Red Hat Enterprise Linux organization, working together with customers and partners on the successful definition, execution and delivery of Red Hat Enterprise Linux. Linux is the language of the wider ecosystem, pulling together the best technologies and platforms from an extensive list of software providers and solutions. Our strategy is built on being able to consume Linux wherever and however you want it, and the commitment we have seen to Red Hat Enterprise Linux from our partner ecosystem has been phenomenal and is essential to create value.

  • Being a Technical Account Manager (TAM) - A day in the life

    IT operations team members work hard to keep systems up and running, often pulling their hair out for resolutions after hours behind the scenes to ensure a seamless front-end experience for their users. But, even superheroes need saving sometimes.

    If you’ve struggled to fix your encryption policies after reading article after article online or need some guidance to pull together a proof of concept for your organization’s big migration to the cloud, perhaps a Red Hat Technical Account Manager (TAM) can be a part of the answer you’ve been searching for.

    Or maybe you’re an expert troubleshooter and audit log guru and want to use those superhero skills to help more companies manage their operations. Some time back, I read a post over on Reddit (written by someone who was considering working for Red Hat) asking if there were any TAMs that would be willing to talk about their job. Here’s a glimpse into a day on the job as a Red Hat TAM.

  • 6 benefits of AIOps

    As IT systems continue to evolve and grow, their scale and complexity are becoming increasingly difficult to manage. The sheer volume of data these systems generate is overwhelming, and -- without sufficiently intelligent monitoring and analysis tools -- can result in missed alerts, opportunities and excessive (and expensive) downtime.

    With the advent of big data and machine learning, however, a new category of IT operations tool has emerged: AIOps.

  • David Cantrell: rpminspect-1.8 released

    rpminspect 1.8 is now available. I know it’s been merely days since the previous release, but this release includes bug fixes for the new unicode inspection.

  • Debarshi Ray: Toolbx: Red Hat is hiring a software engineer

    The Desktop Team at Red Hat wants to hire a software engineer to work full-time on Toolbx (formerly known as Toolbox) with me, and hopefully go on to maintain it in the near future. You will be working upstream and downstream (Fedora and RHEL) to improve the developer and troubleshooting experience on OSTree-based Linux operating systems like Fedora Silverblue and CoreOS, and extend some of the benefits to even traditional package-based OSes like Fedora Workstation.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
