  • Supporting Red Hat partners in a changing world

    With the reimagined Red Hat Summit Virtual Experience next week, we have created new ways for partners to connect with Red Hatters and each other, tune into keynotes and experience product demonstrations - all in a free virtual environment. That includes the North America Partner Experience, formerly known as the North America Partner Conference, which provides an opportunity for our partners to connect with each other, network with industry thought leaders and learn about the latest updates from Red Hat.

    I joined Red Hat last month, in part, because of its commitment to the open source way, built on a foundation of collaboration and engagement. It was immediately evident to me that this is especially true within our partner ecosystem. Our partners are uniquely positioned to support customers in new and impactful ways today and well into the future. Red Hat is here to help, and to support our partner ecosystem right now, we’re offering some new tools and resources.

  • Red Hat Delivers Force Multiplier for Enterprise IT with Enhanced Intelligent Monitoring, Unveils Latest Version of Red Hat Enterprise Linux 8

    Red Hat, Inc., the world’s leading provider of open source solutions, announced the general availability of Red Hat Enterprise Linux 8.2, the latest version of the world’s leading enterprise Linux platform and the foundation for Red Hat’s hybrid cloud portfolio. To help better address the IT challenges presented by shifting global dynamics, Red Hat believes that the operating system should do more than “just work;” it should help stabilize operations today with the capacity to support and embrace innovation later.

    “Building servers that are tuned, ready-to-go and more secure from day one is a key need for our IT organization. Red Hat Enterprise Linux with Red Hat Insights gives us this capacity, enabling us to deploy servers that are immediately usable and meet our specific needs as they go live” Steve Shortplatforms manager, UNIX, Kingfisher PLC

  • Optimizing RHEL 8 to run the Java implementation of the Minecraft server

    As we all find ourselves at home these days many of our kids have requested help with gaming. Minecraft is a common game, loved by millions, played by kids of all ages, and a good teaching tool for how one can optimize the Red Hat Enterprise Linux (RHEL) platform for hosting.

    For those who are not familiar with it, Minecraft is a client-server game, meaning clients can connect to a Minecraft server to share the experience with other gamers.

    This post will go through a number of performance optimizations you can configure in RHEL to make your Minecraft Server experience the best it can be. There are a few architectural flavors of Minecraft; I will focus on the Java implementation of the Minecraft server on RHEL 8. Note that this is only compatible with the Minecraft: Java Edition client.

    I will break down the performance optimizations into five key areas: Operating system, disk I/O, memory, Java and Kernel security mitigations.

  • Five best practices for administering remote systems

    The first step to managing a remote system is... well, being able to manage it! Remote access protocols, such as SSH (and in rare cases, remote desktop), enable you to configure and manage your systems from anywhere. But you don't want your remote management strategy to turn into a security risk inadvertently. You should always take the time to understand the remote management protocol or system that you are using and secure it accordingly.

  • Linux housekeeping: Virtual machine storage sprawl

    In this final entry of my three-part mini-series focusing on Linux housekeeping, I cover virtual machine storage sprawl. Upon first glance, you might believe that virtual machine storage sprawl is the same problem as virtual machine sprawl, but it isn't. Sure, it's related, but there are key differences. Virtual machine (VM) sprawl is the problem of creating virtual machines and then never decommissioning them. They're created for whatever reason and then left to linger for undetermined amounts of time until an angry sysadmin decides to burn everyone's eyes with a white-hot email describing the issue in painful detail. VM storage sprawl is the copying, storing, and ignoring of VM disk images on shared spaces such as public drives or random network shares. Now it's a housekeeping problem. And, specifically, a Linux sysadmin problem.

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.
