  • The Sysctl Command in Linux - ByteXD

    In this tutorial we’ll learn the fundamentals of the sysctl command.

    To start off, have you wondered how an operating system can use the hardware on which it is running?

    It’s the kernel that acts as an interface between an operating system and the hardware. It enables the communication between both entities and is part of the operating system that runs on the hardware.

    A user, however, does not interact with the kernel but rather works in a limited space to manage files and execute programs.

    So, for example, does Ubuntu have a kernel? Yes, it does.

    We can also make certain modifications to the kernel using the sysctl command, which is this article’s focus.

    Let’s proceed to take a look at this concept.

  • How to Use the Grep Command in Linux - ByteXD

    In this tutorial, we’ll cover how to use grep command along with its various parameters. I’ll be using Ubuntu 20.04 for examples, but the grep command should work the same in all Linux distros.

    The grep command in Linux is used to search for a text pattern in a file or in a set of files. It can be used to search in a set of files for a particular pattern and to display the found lines.
    It can also be used to match text patterns in command line output. For a concrete example of this you can check the Mixing the grep Command with Other Commands section of this article.

    Note: Even though there’s slim chance that the grep command is not installed on the distro you’re using, you should to install it using your distribution’s package manager.
    Let’s proceed to take a look at the grep command.

  • What to do when 2FA won't allow you into your Linux servers - TechRepublic

    Recently, I had an incident where a two-factor authentication-enabled Linux server wouldn't allow me in via SSH. Fortunately, I had physical access to the server, so it wasn't a complete disaster. Had I not been able to log into the machine on site, I would have had to count on someone on-premise to take care of the situation. In some cases, that would not do.

  • 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.
