  • How to install Go 1.18 on Rocky Linux/AlmaLinux – NextGenTips

    In this tutorial, we are going to explore how to install go on Rocky Linux 8.5

    Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast.

    Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions.

    Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection.

    In this guide, we are going to learn how to install golang 1.18 on Fedora 35.

    Go is not yet released. There is so much work in progress with all the documentation.

  • How I fell into the self-hosting rabbit hole in 2021 | Windows Central [Ed: Windows fanatics realising that GNU/Linux enables them to self-host]

    Also running on that same Raspberry Pi is a rudimentary local file server. It's a simple Samba setup, mostly in existence because I read a blog post on it and thought I'd give it a try. It's set up with a small USB flash drive connected to the Pi and I've been using it to share files across my home network that I don't need long-term or syncing to all my devices. It probably won't be around too much longer, but it's been handy.

  • Linux Fu: Don’t Share Well With Others | Hackaday

    In kindergarten, you learn that you should share. But for computer security, sharing is often a bad thing. The Linux kernel introduced the concept of namespaces starting with version 2.6.24. That’s been a few years ago, but namespaces are not used by many even though the tools exist to manipulate them. Granted, you don’t always need namespaces, but it is one of those things that when you do need it, the capability is priceless. In a nutshell, namespaces let you give a process its own private resources and — more importantly — prevents a process from seeing resources in other namespaces.

    Turns out, you use namespaces all the time because every process you run lives in some set of namespaces. I say set, because there are a number of namespaces for different resources. For example, you can set a different network namespace to give a process its own set of networking items including routing tables, firewall rules, and everything else network-related.

  • 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.
