  • Ansible Playbook to Install and Setup Apache on Ubuntu

    Normally, there is a control node and host nodes. Ansible is installed in the control node and will execute the playbook to deploy in host nodes. In this lab, we are going to install and use it in a single node.

    [...]

    Ansible is a helpful tool as it is agentless and writing configuration is easy. You can browse more configurations from ansible official documentation. Please do comment if you have any issues while writing the playbook on ansible.

  • Setting up a VM on Fedora Server using Cloud Images and virt-install version 3 - Fedora Magazine

    The standard virtualization tool for Fedora Server is libvirt. For a long time the only way to create a virtual Fedora Server instance was to create a libvirt VM and run the standard Anaconda installation. Several tools exist to make this procedure as comfortable and fail-safe as possible, e.g. a Cockpit module. The process is pretty straight forward and every Fedora system administrator is used to it.

    With the advent of cloud systems came cloud images. These are pre-built ready-to-run virtual servers. Fedora provides specialized images for various cloud systems as well as Fedora Cloud Base image, a generic optimized VM. The image image is copied to the server and used by a virtual machine as an operational file system.

    These images save the system administrator the time-consuming process of many individual passes through Anaconda. An installation merely requires the invocation of virt-install with suitable parameters. It is a CLI tool, thus easily scriptable and reproducible. In a worst case emergency, a replacement VM can be set up quickly.

    Fedora Cloud Base images are integrated into the Fedora QA Process. This prevents subtle inconsistencies that may lead to not-so-subtle problems during operation. For any system administrator concerned about security and reliability, this is an incredibly valuable advantage over libvirt compatible VM images from third party vendors. Cloud images speed up the deployment process as well.

  • 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.
