    In this tutorial, we will show you how to install KVM on Debian 11. For those of you who didn’t know, KVM (Kernel-based Virtual Machine) is an open-source full virtualization solution for Linux Systems running on x86 hardware with virtualization extensions (Intel VT or AMD-V). You can use KVM to run multiple operating systems such as Windows, *BSD, Linux distribution using virtual machines. Each virtual machine has its private disk, graphics card, network card, and more.

    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 KVM virtualization on a Debian 11 (Bullseye).

  • How to Install OpenEMR Medical Office Workflow Software on Ubuntu 20.04 – VITUX

    A medical office’s workflow can be a tangled mess of electronic documents, including insurance forms and appointments. In order to streamline the process for both patients and staff members, it is necessary that they have access to efficient software – which offers all necessities from scheduling weeks in advance with no reminders around receptionists’ availability slots or how much inventory each pharmacy has on hand at any given moment.

    Are you looking for a medical practice that can fit your needs? Many options are available, including proprietary software. However, there is another option: open source solutions. The OpenEMR project offers an easy way to get started with this type of digital health innovation.
    In this guide, we will walk you through the process of installing OpenEMR on an Ubuntu Server 20.04.

  • How to Install Gradle Build Tool on Debian

    Gradle is a build automation tool that is built on the ideas of Apache Ant and Apache Maven. Gradle replaces the XML form used by Apache Maven for defining the project settings with a Groovy-based domain-specific language (DSL).

    Gradle is using a Groovy-based DSL, which is more convenient for developers. This DSL also provides for dependency management, automatic downloading and documentation. It can be used to compile the source code, run tests and generate reports on the same project in a single command-line.

    While Gradle is primarily a build tool, it can also be used as a general-purpose task runner. It provides the ability to create native software packages in Windows EXE installer, and dmg packages.

    Gradle does not provide dependency management since it can load plugins to support various source code management tools, but Gradle has a rich API that allows you to create custom tasks or even new plugins. There are also various community-provided plugins available for different types of dependency management.

    The Gradle tool is written in Java, but it can work with any language as long as there are plugins available for the respective language.

    Linux users will be happy to know that Gradle is available natively for Linux. Gradle has many advantages over Maven, including faster incremental builds due to the use of Ivy dependency management, which actually makes it possible for developers to avoid using maven-release-plugins. The release process itself becomes less painful.

  • Add, Delete And Grant Sudo Privileges To Users In Fedora - OSTechNix

    Using sudo program, we can elevate the ability of a normal user to run administrative tasks, without giving away the root user's password in Linux operating systems. This guide explains how to add, delete and grant sudo privileges to users in Fedora 35 desktop and server editions.

    I've divided this guide in three sections. The first section teaches you how to create a new user. In the second section, you'll learn how to give sudo access to the existing user. And in the last section, you will know how to remove sudo access from a user. I've also provided example commands in each section, so you can understand it better.

    First, we will start with giving sudo access to a new user.

  • Using RHEL System Roles to manage Linux at scale

    One such RHEL management tool to consider is RHEL System Roles, a collection of supported Ansible roles and modules providing consistent and abstracted configuration interfaces to manage RHEL at scale. There are a large variety of roles that cover many aspects of RHEL management.

    RHEL System Roles are currently distributed as an RPM in RHEL and as a collection on Ansible Automation Hub (available for Ansible subscribers).

    Ansible also supports a new format called execution environments, which are packaged as container images. RHEL System Roles doesn't currently have an execution environment container image, but the upstream Linux System Roles project does. During our recent presentation Secure and monitor RHEL: Using the Linux System Roles execution environment with Ansible Automation Controller at AnsibleFest 2021, we covered how you could use this upstream execution environment and Ansible Automation Controller to help secure and monitor RHEL.

  • 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.
