  • How To Install PostgreSQL on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install PostgreSQL on AlmaLinux 8. For those of you who didn’t know, PostgreSQL is a free-opensource object-relational database management system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.

    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 through the step-by-step installation of MySQL databases on an AlmaLinux 8. You can follow the same instructions for Rocky Linux.

  • A Survey of Init Systems

    While most distros ship with systemd, init alternatives exist. Here are a few of the leading init systems available for Linux.

    Not long ago, few Linux users cared about the init system. It mostly ran in the background, the first process to run during bootup, and the one that started and, if necessary, stopped the others. However, the init system came under closer scrutiny in 2012-2015, when systemd started to be used as the init system in most major distributions. Many complained about its complexity and the way that it was promoted by officials in major distributions. Thanks to the Devuan distro, some even began to talk about “Init Freedom,” the right to choose your init system as though it was as basic as the four software freedoms advocated by the Free Software Foundation. Others replied that init freedom would complicate compiling packages and general distro releases.

    Today, the discussion continues. While most distributions ship systemd, a number of alternatives exist. Below is a quick summary of the leading init systems. If you are interested in trying one, the search filters on DistroWatch can let you locate which distro, if any, defaults to the init system that interests you. Alternatively, you can replace your existing init with another one, although the task is not for the faint-hearted, nor recommended for any except well-informed experts.

  • Launch Flatpaks from your Linux terminal

    The Flatpak application distribution model is helping developers target Linux in a new and easy way, and it's helping Linux users install more applications without worrying about what version of Linux they're running. It's an exciting technology, and on my Fedora Silverblue system, it's the default package installation method. All of my desktop applications on Silverblue and several of my favorites I use on Slackware are running as Flatpaks.

    There's one thing that makes Flatpak a little awkward in some cases, though, and that's its naming scheme. For instance, when I install Emacs as a Flatpak, it's registered on my system as org.gnu.emacs. This is done, apparently, for fear of clobbering the name of an existing system-level application—if I already have Emacs installed, then what's the differentiation between /usr/bin/emacs and the Flatpak installation of Emacs?

  • How to install Gnome on FreeBSD 13

    The initial setup of FreeBSD does not provide the Desktop Environment. It is command line mode only. If you want to use this FreeBSD 13 as your laptop or personal computer operating system, then you will need to install a Desktop Environment.

    There are some version of Desktop Environments available. They are Gnome, KDE and Xcfe. In this tutorial we will install the Gnome.

  • Vincent Bernat: Jerikan: a configuration management system for network teams

    There are many resources for network automation with Ansible. Most of them only expose the first steps or limit themselves to a narrow scope. They give no clue on how to expand from that. Real network environments may be large, versatile, heterogeneous, and filled with exceptions. The lack of real-world examples for Ansible deployments, unlike Puppet and SaltStack, leads many teams to build brittle and incomplete automation solutions.

  • How to transfer files between Android and Linux with Warpinator - TechRepublic

    One would think, given the Linux roots in Android, that transferring files between the two platforms would be built into both operating systems. It's not. However, adding such a feature isn't nearly as hard as you think, thanks to a tool created for Linux Mint, called Warpinator. Although you won't find Warpinator in the standard repositories for distributions outside of Mint, a Flatpak was created, so any distribution that supports this universal installation package can enjoy easy file transfer between Android and Linux.

    Let me show you how to make this bit of magic happen.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 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 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
