  • Libvirt/KVM Backup on Debian Bullseye – Michael Ablassmeier – ..

    The libvirt and qemu versions in Debian Bullseye support a new feature that allows for easier backup and recovery of virtual machines. Instead of using snapshots for backup operation, its now possible to enable dirty bitmaps. Other hypervisors tend to call this “changed block tracking”.

    Using the new backup begin approach, its not only possible to create live full backups (without having to create an snapshot) but also track the changes between so called checkpoints, which is very useful for incremental backups.

    Over the course of the last few months, i have been working on a simple backup and recovery utility called virtnbdbackup

  • LFCS - Managing Groups |

    The previous article covered Managing Users. Administrators need to be able to not only manage new and existing users, but also the Groups that the users can belong to on a system.

    Keep in mind that these skills are more beneficial in a larger network in a domain-style environment than on a single system. If you worked in a corporation with multiple departments then it is much easier to place all users in a department into a single Group for that department. Once you assign permissions to the Group then all users have the same permissions. Of course, if you assign more permissions to specific Users, then those Users will have more permissions above the Group permissions.

  • 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.
