  • How to use for/while/until loop in bash

    Undoubtedly the most useful feature of bash scripting is loop control. In any imperative programming language like bash, loop statements are commonly used along with conditional statements to perform repetitive tasks. In case of bash, three different types of loop statements are available: for, while and until. Each of these loop statements comes in handy in slightly different circumstances.

  • The mysterious change of a checksum

    Within KDE we have a service called the binary factory. It’s a Jenkins driven build pipeline which we use in the KMyMoney project to build certain binary installable versions of the project. For the generation of our AppImage version we package all dependencies into a large tar file so that we don’t have to rebuild them every day.

    Due to new versions of the online banking libraries we use, I updated some package information and let the service do its thing to create the tar file with the pre-build dependencies. This is usually a matter of a few hours. When I checked the progress after a while, I found out that the build had failed.

  • 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.
