  • Celebrate 30 Years of Linux With Training & Certification Offer

    On August 25, 1991, Linus Torvalds posted the now famous Usenet message announcing he was building a free operating system. In the 30 years since, that operating system – Linux – has become the most important open source software project in history, powering all supercomputers, serving as the backbone of the cloud and internet, running a majority of mobile phones and mainframe computers, and even operating on the International Space Station.

    After all this time Linux is more important than ever. In fact, the 2020 Open Source Jobs Report from The Linux Foundation and edX found that Linux is the most in demand skill amongst technical hiring managers. This is largely due to rapidly growing adoption of cloud technologies which run on Linux.

  • Microarchitecture rpm macros

  • LetsEncrypt SSL certificates for vhosts within the mail stack – via Postfix (SMTP) and Dovecot (IMAP)

    For a long time, I didn’t care about using self-signed SSL certificates for the mail stack because 1) they still secured the connection to the server, and 2) those certificates weren’t seen or utilised by anyone other than me. However, for my datacentre infrastructure which houses clients’ websites and email, using self-signed or generic certificates (even for the mail stack) wasn’t a very good solution as mail clients (e.g Thunderbird or Outlook) notify users of the problematic certs. Clients with dedicated mail servers could use valid certificates (freely from LetsEncrypt) without problem, but those on shared infrastructure posed a different issue—how can mail for different domains all sharing the same IPv4 address use individualised certificates for their SMTP and IMAP connections? This article will explain the method that I used to assign domain-specific certificates for the full mail stack using LetsEncrypt’s certbot for the certs themselves, the Postfix MTA (mail transfer agent [for SMTP]), and the Dovecot IMAP server. This article is tailored to Gentoo Linux, but should be easily applied to nearly any distribution.

  • 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.
