  • Backup List of Installed Packages and Restore Them on a Freshly Installed Ubuntu System - TREND OCEANS

    For new Linux users, reinstalling the operating system is a hurdle. It’s funny, but I’ve seen many Linux users manually install packages and applications from their previously installed Linux system into their freshly installed Ubuntu Linux system.

    I used to be one of them, and you might be too. So, let’s forget the time we have wasted and learn today how to backup a list of installed packages and restore them on a freshly installed Ubuntu system.

  • How to Enable Arch User Repository (AUR) in Manjaro Linux

    The Linux operating system is associated with various distributions whose design and development footprints are focused on meeting different user requirements. One such distribution is Manjaro Linux.

    Since it is based on the Arch Linux operating system, this free and open-source Linux distribution prioritizes accessibility and user-friendliness as its major design parameters. The Pacman package manager and its rolling release update model are also key identifiers of Manjaro Linux.

  • Boot into an Older Kernel By Default in Ubuntu & Other Linux

    Here’s a possible scenario. Your system received a kernel update but somehow things are not working as smoothly as previously.

    You realized that if you boot into the older kernel (yes, you can downgrade kernel), things are back to normal.

    That makes you happy with a little inconvenience. You have to manually select the older kernel at each boot.

    This problem was faced by an elderly It’s FOSS reader. The new kernel update in Linux Mint wasn’t working as expected. Booting into the older kernel ‘fixed’ the issues but choosing the older kernel at each boot was a problem.

    Removing the new kernel (while using the older kernel) is not a good idea because the new kernel will be installed and used with the next system updates.

    So, I suggested booting into the older Linux kernel by default. How to do that? That’s what I am going to show you in this tutorial.

  • 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.
