  • How to Stress Test Your CPU in Linux | Tom's Hardware

    A key matrix for determining the vitality of a Linux distro, or the hardware that it runs on, is system performance. Depending on your purpose, you can choose from a variety of dedicated tools to monitor the different components such as CPU frequency, temperature and memory utilisation. But if you favour the CLI, like us, you’ll rather enjoy working with S-TUI.

    With S-TUI, which is an acronym for Stress-Terminal UI, you can simultaneously monitor CPU temperature, frequency, power and utilisation. The utility presents all the information graphically and can even be used to export the data into CSV files. Better still, you can configure S-TUI to automatically launch scripts when the values of any of the components being monitored breaches the defined threshold values. When coupled with stress, another command-line utility, S-TUI can also be used to stress-test your system.

  • 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.
