  • How To Install Certbot on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install Certbot on AlmaLinux 8. For those of you who didn’t know, Certbot is a client that fetches the SSL certificate from the Let’s Encrypt authority and automates its installation and configuration. This eliminates the pain and hustle of accomplishing the entire process manually.

    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 Certbot on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.

  • How do you pass a Named Argument in a Shell Script?

    The shell scripts in Linux allow you to write programs with hard-coded values and programs that can take user inputs at runtime. These user inputs are known as parameters or arguments. All of us are generally familiar with passing normal arguments to the shell scripts. However, you might sometimes feel the need to pass “Named Arguments” to your shell scripts. This article will guide you more about what exactly are named arguments and their need in shell scripts. After that, we will share an extensive example of passing the named arguments to a shell script in Ubuntu 20.04.

  • How to Copy and Paste in Linux and Ubuntu Terminal

    When you switch to Linux from Microsoft Windows, especially if you are a programmer, there is a possibility that you might struggle to copy and paste commands or lines in the Linux Terminal window.

    Even when I ported to Ubuntu from Windows a decade ago, I struggled to copy and paste lines in the Linux terminal. At that time, I thought I’m the only user struggling to copy and paste. However, while searching on the Internet, I realized that it is a global problem.

    The reason is a keyboard shortcut and mouse keys to copy and paste lines in the Linux terminal windows are not the same as the ones we use on Windows.

    The key bindings for copy and paste operations are dependent on the specific terminal emulator you are using. In Linux, by default CTRL + C key binding is used for sending an interrupt signal to the command running in foreground. Hence, the Linux terminals do not use the standard CTRL + C and CTRL + V for copy and paste operations.

  • How to enable WLAN0 on Kali Linux | FOSS Linux

    Before getting into wlan0 and how to enable it, let us dig a little into the difference between WLAN and Wi-Fi and look at how it works. To begin with, the abbreviation, WLAN, stands for “Wireless Local Area Network.” Local in WLAN generally means a network contained in a geographical location, building, or campus. The W stands for wireless.

    These two terms (“WLAN and Wi-Fi) are interlinked and used interchangeably, thus creating misunderstandings among many users.

  • Install Chromium browser Debian 11 Bullseye - Linux Shout

    The steps given here to install Chromium on Debian 11 will also work for Debian 10 Buster and other previous versions including Ubuntu, Linux Mint, MX Linux, Kali Linux, and more…

    Chromium is an open-source browser from Google, on which “Google Chrome” is based. With this web app, developers and users always get the latest version of the browser for their system. It is available for Windows, Linux, macOS, and Android, which is mainly not intended for end-users, but only for developers because Google tweaks the Chromium source code almost every day, hence you should always use the latest version.

    Well, if you don’t want the proprietary Chrome browser but the open-source one then Chromium which is identical to that of Chrome can be installed easily.

    However, there are some restrictions such as Chromium does not have a Flash Player, and PDFs cannot be displayed in the browser.

  • 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.
