  • Forgot Your Linux Mint password- Here is a way to recover it.

    Just like Ubuntu Linux distros, resetting passwords on Linux Mint is the same, you have to use the advance boot option to perform the job. Using this we can even change or reset the root password or some other users as well. Just what you have to do is, restart your Linux PC or laptop in recovery mode and follow the steps given in this article to change the password.

    Linux Mint is quite easy to use distro, however, if don’t remember your current password then just like any other operating system, it won’t let you log in. However, as there is no option to recover the current password of your Linux root and other users. Thus, the only option left with us is resetting it manually using the command line. Well, don’t worry, even if you are a Linux beginner, the steps to do that are really a piece of cake.

  • Linux 101: How to quickly open a terminal in a specific directory - TechRepublic

    Unlike when working with a server, when using the Linux desktop, I spend more time with a GUI than I do the command line. That doesn't mean I never touch the command line from within a desktop environment. In fact, I do so on a daily basis. I also try to use it as efficiently as possible.

  • Arch-linux building from source – and Obarun to the rescue

    What if, there was a benefit in building from source, a system that is commonly used by pre-fabricated binary packages, like Arch or any of its forks and desktop flavors? What Arch considers a “clean-chroot” is primarily of need to developers ensuring their package can be both satisfied for all dependencies AND are reproducible, as long as this can be achieved within a constantly rolling distribution. That is open and nearly free condition for you.

    [...]

    Scratch most of this for several reasons. We are not developers, we are building our own system like Gentoo-ers, k1ss-ers, Crux-ers, and others do. We want to make sure that each of our packages fits well within the parameters of our specific machine, and it wasn’t built on another machine that may not be 100% compatible to ours. One of the aspects of Arch’s clean chroot that shouldn’t be neglected is the tmpfs space a chroot is given. That 20G is borderline enough to build some packages … that may be compiling for half a day and end with an error message “no space left on device“. That is a very sad waste of electricity and processing mileage.

  • 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.
