  • How to install mediawiki on FreeBSD - Unixcop

    In my case, I’ve installed our own mediawiki to document my work.When I started working here, my then boss gave me my first task: to install some server for some service and hand me his cheat sheet on how to do it. This cheat sheet was an actual sheet of paper handwritten; he also had a block of paper with different cheatsheet for different services.

    Less than a month after that first task, uncountable visits to his desk looking for another cheat sheets and a couple of new systems (that I didn’t document how to do it), we both realized that we need a better system. Also my handwriting it’s very hard to read and in the future some new people could begin to work with us and we will need better documentation. That’s why I suggested to install mediawiki and my boss was ok.

  • How to Burn ISO to USB

    In this guide, we will show you how to burn ISO files to a USB drive for different operating systems. We will also go through the process of booting and extracting ISO files to new devices.

    [...]

    An ISO file, or an ISO image, is used to create an archived copy of large sets of data, which is stored for backup purposes. Therefore, it’s best to view ISO files as smaller versions of original files. That’s why large programs, video games, and operating systems are usually duplicated as ISO files.

    While ISO files used to be burned to CDs and DVDs, in today’s modern practice, they are more frequently burned to USB drives. Apart from storing and backing up large amounts of data, ISO files are also extracted and booted from USB drives to be transferred to new devices.

  • 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.
