  • Doing the cloud differently

    Jeff Dike, one of the contributors to Linux, had developed a technology called User-mode Linux. UML, as it was known, allowed developers to create virtual Linux machines within a Linux computer. This Matrix-like technology was groundbreaking and opened the door for the virtualized cloud we know today.

    One of the developers Dike’s technology enabled was a young technologist named Christopher Aker. He saw an opportunity to use this technology not to build the next Salesforce or Amazon, but to make cloud computing less complicated, less expensive, and more accessible to every developer regardless of where they were located, what their financial resources were or who they worked for. The company he built — Linode — helped pioneer modern cloud computing.

  • A day in the life of a quality engineering sysadmin

    Let me begin by saying that I was neither hired nor trained to be a sysadmin. But I was interested in the systems side of things such as virtualization, cloud, and other technologies, even before I started working at Red Hat. I am a Senior Software Engineer in Test (Software Quality Engineering), but Red Hat, being positioned so uniquely because its products are something primarily used by sysadmins (or people with job responsibilities along similar lines) and also most of Red Hat’s products are primarily focused on backend systems-level instead of user application level. Our testing efforts include routine interaction with Red Hat’s Virtualization, OpenStack, Ansible Tower, and Hyperconverged Infrastructure.

    When I was hired, I was purely focused on testing Red Hat CloudForms, which is management software for the aforementioned environments. But as one of our previous senior software engineers departed to take on another role within Red Hat, I saw an opportunity that interested me. I was already helping him and learning sysadmin tasks by then, so after looking at my progress and interest, I was a natural successor for the work in my team’s perspective. And hence, I ended up becoming a sysadmin who is working partly as a software engineer in testing.

  • 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.
