  • How to Create a Sudo User in Debian

    The sudo command (originally standing for superuser do) is a program in Unix-like operating systems for running commands as other users, by default root.

    Sudo allows a system administrator to give selected users the ability to run some (or all) commands as root while logging all commands and arguments.

    Commands may be run as a specific user, the user’s default shell, or any other user’s shell. Sudo operates on a per-command basis.

    By default, Linux prevents access to certain parts of the system for non-root users, but with the sudo command you can access these parts without needing to log in as root every time.

    It’s important to take into careful consideration what users on your system can use sudo. Commands that require root privileges aren’t commands that a standard user usually needs access to, for risk of damaging the system if something is done incorrectly – something that the system administrator wouldn’t allow to happen. This is why this has been the security model for years.

  • How To Install ReactJS on Ubuntu Debian 10

    In this tutorial, we will show you how to install ReactJS on Debian 10. For those of you who didn’t know, React.js is an open-source JavaScript library, and the primary usage of it is to create user interfaces (UIs) that generally help to create single-page applications. It is developed and maintained by Facebook and a large community of developers. ReactJS can be used in the development of Web Applications or Mobile Apps.

    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 ReactJS on a Debian 10 (Buster).

  • PHP 8.1 Feature Work Includes Adding Enums, Fsync Function - Phoronix

    While most haven't even moved to PHP 8.0 yet in their Linux distribution default packages let alone in production environments, PHP 8.1 is under development and like clockwork should be out around the end of November as usual for their yearly release dance. In two months already the PHP 8.1 alpha releases should start up.

    In two months it's already time for the PHP 8.1 alpha releases to begin. The PHP 8.1 schedule is like most years and after the three bi-weekly alpha releases it puts the PHP 8.1 feature freeze towards the end of July before moving onto the beta releases and then the many release candidates. If all goes well, PHP 8.1.0 will be out on 25 November.

  • 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.
