  • [Updated] How to Install, Create and Manage LXC in Ubuntu/Debian

    Over the last decade, the open-source community has seen a steady shift to containerization as the preferred way of deploying applications thanks to the numerous benefits it offers such as portability, flexibility, increased security, and easier management of applications. Popular containerization technologies include Docker, Podman, and LXD.

    Written in Go language, LXD (pronounced as Lekseed) is described as the next generation system container and virtual machine manager that allows you to manage your containers and virtual machines from the command line, or by leveraging a REST API or other third party tools. LXD is an open-source project and is an extension of LXC (Linux Containers) which is OS-level virtualization technology.

  • How to Install & Enable EPEL / EPEL Next Repository on CentOS 9 Stream - LinuxCapable

    EPEL, which stands for Extra Packages for Enterprise Linux, is an open-source and free repository that provides extra packages for Enterprise Linux. The EPEL repository was created because Fedora contributors wanted to use Fedora packages they maintain on RHEL and other compatible distributions such as CentOS, Rocky Linux, AlmaLinux, to name a few.

    The EPEL repository is also known for bringing additional packages and updated packages that may be behind in the core repository, along with dependencies required by other external repositories, for example, the Remi PHP repository.

    In the following tutorial, you will learn how to install the EPEL repository and the EPEL Next repository, which is the next testing version that can come into use for newer packages when major upgrades occur to the core distribution on CentOS 9 Stream.

  • 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.
