  • How to Offline Update Fedora Workstation? – Linux Hint

    Keeping the operating system up-to-date is important as updates contain bugfixes, performance improvements, security patches, and others. In the case of Linux, keeping the system updated mostly means keeping all the installed packages up-to-date.
    Offline updating is an interesting concept when a system needs to be updated but without any reliable internet connection. In such a situation, the update packages are manually downloaded from a different source and applied to the offline machine.

    In this guide, check out how to offline update the Fedora workstation.

  • How to add PHP-FPM support for NGINX sites - TechRepublic

    If you've decided to make the switch from Apache to NGINX, one of the questions you might find yourself asking is how to add support for the PHP Fast Process Manager (PHP-FPM). For those that might not know, PHP-FPM is a FastCGI handler for PHP scripts and apps, which makes it possible for a website to handle higher loads. PHP-FPM is much faster than traditional CGI-based multi-user PHP environments and also allows for the hosting of multiple applications using different versions of PHP.

    I want to walk you through the process of installing PHP-FPM and then enabling it in your NGINX sites. It's not quite as simple as it is with Apache, but it shouldn't be much of a challenge for any IT pro.

  • How to compile NGINX for ModSecurity support on Ubuntu Server 20.04 - TechRepublic

    ModSecurity is the most widely-used and respected web application firewall for open source web servers. It can be used with both Apache and NGINX to provide protection from a number of HTTP attacks (such as SQL injections and cross-site scripting) against web-based applications like WordPress and Nextcloud. In other words, this module should be considered a must-use.

  • Sharing audio to a videoconference using pulseaudio · Tomáš Tomeček

    Since I do all the meetings via videoconferencing software in this pandemic, from time to time I need to do something extra than just sharing my face and voice: share a video from my laptop.

    Luckily, pulseaudio has your backs, it’s just not that trivial.

  • Ventoy, multiboot DVD creator

    The other day, I was looking for a tool to create a USB drive with multiple installer ISOs on it. Mainly, I needed a Fedora installer DVD (for my laptop, to make the switch to btrfs), and a Red Hat Enterprise Linux 8.3 DVD to reinstall my dad’s workstation (which currently runs CentOS 8, and is in need of actual RHEL).

    There used to be a tool called Yumi to do this with, but their site is dead, and so is multiboot.org. I’m not even going to bother linking to them Confused

    Then, on some forum about multiboot DVDs, I read that their demise might have to do with something called “ventoy”, which is being actively maintained and would make both obsolete. Or so they say.

    Needless to say, I was intregued.

  • 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.
