  • LFCA: Learn Fundamentals of Cloud Computing – Part 13

    Cloud computing is a popular buzzword that refers to an on-demand technology that has taken over the technology world by storm and simplifies the way we provision IT resources and access data. To better understand and appreciate the concept of Cloud computing, let’s go back in time and see how the technology environment looked like before the advent of cloud technology.

    Traditionally, an organization would procure physical servers and set them up in its own office. As the company grew, the growing business demands would compel the company to shift its resources to a data center where it would procure additional resources such as servers, networking equipment, backup power, and cooling systems. Now, this worked just fine but the setup presented a couple of challenges.

  • Manipulating the Ubuntu dock to keep favorite apps handy

    If you're a Linux user, you are undoubtedly familiar with the "dock"--that column of icons lined up on the side of your screen that includes important applications, your favorites. It allows you to open the applications simply by left clicking on one of the icons.

    But did you know that you can add or remove applications from your dock and sometimes even change the location of the dock on your screen? This post shows you how to make these changes on Ubuntu.

    To add an application to the dock, start the application in the usual way. Once it's open, you should see that it's been temporarily added to the dock. If you want it to stay there for future use, just click on its icon in the dock and select "Add to Favorites" from the menu that opens.

  • 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.
