  • Basic Linux Kernel module administration commands

    The kernel of a Linux system is the core that everything else in the operating system relies on. The functionality of the kernel can be extended by adding modules to it. As such, a user can fine tune their kernel settings by enabling or disabling modules. This level of granular control is one of the many reasons why users love Linux in the first place.

    In this guide, we'll go over some of the most essential kernel module administration commands on Linux. Knowing these commands will help you understand the components that have been loaded into your system's kernel, and will also allow you to load, reload, or unload modules in the system kernel.

  • Linux Fu: Superpowers For Mere Mortals | Hackaday

    You can hardly mention the sudo command without recalling the hilarious XKCD strip about making sandwiches. It does seem like sudo is the magic power to make a Linux system do what you want. The only problem is that those superpowers are not something to be taken lightly.

  • How To Install Suricata on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install Suricata on AlmaLinux 8. For those of you who didn’t know, Suricata is a free and open-source, mature, fast, and robust network threat detection engine. It can function as intrusion detection (IDS) engine, inline intrusion prevention system (IPS), network security monitoring (NSM) as well as an offline pcap processing tool. Suricata inspects the network traffic using powerful and extensive rules and signature language and has powerful Lua scripting support for the detection of complex threats.

    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 through the step-by-step installation of the Suricata on an AlmaLinux 8. You can follow the same instructions for Rocky Linux.

  • Hyperconverged Infrastructure and Harvester

    Virtual machines (VMs) have transformed infrastructure deployment and management. VMs are so ubiquitous that I can’t think of a single instance where I deployed production code to a bare metal server in my many years as a professional software engineer.

    VMs provide secure, isolated environments hosting your choice of operating system while sharing the resources of the underlying server. This allows resources to be allocated more efficiently, reducing the cost of over-provisioned hardware.

    Given the power and flexibility provided by VMs, it is common to find many VMs deployed across many servers. However, managing VMs at this scale introduces challenges.

  • 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.
