  • How To Install Gitlab on Debian 10 - idroot

    In this tutorial, we will show you how to install Gitlab on Debian 10. For those of you who didn’t know, Gitlab is a graphical implementation of git, it is open-source repository management and version control system. GitLab is developed on Ruby on Rails. Using GitLab you can host your source code on your own server. This ensures the security of the code and gives you total freedom on the number of users as well as the number of repositories and the number of files. GitLab provides you with a platform to collaborate on projects and to keep track of changes in code. GitLab has widely used for software development and version control related tasks. In many ways, it is similar to GitHub, except you can install it on your own server.

    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 through the step by step installation of Gitlab on a Debian 10 (Buster).

  • How to Assign/Remap Keyboard Shortcuts for Better Productivity in Linux - Make Tech Easier

    By default, Ubuntu comes with a set of keyboard shortcuts that you can use straight away. However, you may not like the default mappings of some of these keyboard shortcuts. They might be assigned to shortcuts you’re used to using for something else, disrupting your productivity. For example, if you have a keyboard with a media button, that button is automatically mapped to Rhythmbox. If your favorite media player is VLC, you may want to change the keyboard shortcut to your favorite application.

    There are several ways to manage your keyboard shortcuts in Linux. You can do it via Xmodmap (and Xkeycaps) or through your desktop environment’s keyboard/shortcut settings. This article will focus mainly on how to change the shortcuts or assign new ones on two of the most popular desktop environments, Gnome and KDE.

  • How to Add Fingerprint Login in Ubuntu and Other Linux

    Many high-end laptops come with fingerprint readers these days. Windows and macOS have been supporting fingerprint login for some time. In desktop Linux, the support for fingerprint login was more of geeky tweaks but GNOME and KDE have started supporting it through system settings.

    This means that on newer Linux distribution versions, you can easily use fingerprint reading. I am going to enable fingerprint login in Ubuntu here but you may use the steps on other distributions running GNOME 3.38.

  • How to Create an Ansible Test Environment using LXD - buildVirtual

    LXD/LXC is great for setting up test / development environments as it allows us to quickly create Linux based containers that behave like full virtual machines.

    I recently had the requirement to develop an Ansible Playbook to configure a bunch of machines as a web farm. I decided to use LXD/LXC to create an environment where I could test the playbook quickly and easily. This meant I wouldn’t have to worry about needing to build any VMs, or anything external to the system I was working on.

    In the following sections I will show the commands I ran to create the environment, explaining what each part does, before showing the completed script at the end of the page, so please read through to the end! Before continuing, you will need to have installed LXC. Checkout this article on how to install LXC/LXD if you haven’t already.

  • 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.
