  • Intel Readies "PFRUT" For Linux 5.17 To Allow Updating System Firmware Without Rebooting - Phoronix

    Intel open-source engineers have prepared "PFRUT" support for Platform Firmware Runtime Updates for allowing (U)EFI capsule updates to be performed on capable systems without rebooting the system in order to eliminate downtime.

    Intel has worked on PFRUT that is now part of the ACPI specification for allowing platform firmware components to be updated on-the-fly without the need to restart the system. The intent of this is for servers where they need to be "available 100% of the time" and other cases where downtime must be kept to an aboslute minimum. This "pfr_update" driver set for Linux 5.17 introduction seems to be primarily geared for being able to update system firmware in cases of critical bugs or security issues in a timely manner while not introducing any new downtime.

  • 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.
