  • How to install Gnome 41 in Ubuntu 20.04 LTS using PPA - Linux Shout

    While doing this tutorial, Gnome 41 was not still available for Ubuntu 20.04 LTS Focal using the official APT repository. However, we can install Gnome on Ubuntu 20.04 Focal fossa using an unofficial PPA. And here we let you know how to do that?

    Similar to KDE, Gnome has existed for over two decades and has reinvented itself several times during this time. The previous major version of Gnome, 40th, also brought significant visual changes compared to the previous version.

    The Gnome project has released version 41 of its Linux / Unix desktop. In addition to a significantly improved settings dialog, it offers an improved calendar application, “Connections” for remote connections to other computers, and improvements to the Nautilus file manager. On top of that, the developers promise more oomph through various performance improvements.

  • 5 Redhat enterprise based alternatives for CentOS 8 | 7 in 2022

    Here is the list of best RHEL based CentOS 7 or 8 Linux server alternatives or replacements in 2022 to start hosting server applications on Cloud or VPS. Well, if you don’t want to go through articles then AlmaLinux and RockyLinux are the best CentOS alternatives to go with.

    With the end of support in CentOS 8 by RHEL, people start looking for Linux distribution to replace their existing CentOS 8 or looking to upgrade CentOS 7 to some other compatible one. Well, your quest might end here, if you are one of them.

    Although we have an Ubuntu server to replace CentOS, however, there are many users already using RPM-based server applications. Hence, the Debian-based server wouldn’t be a great option. Of course, those who want to start from scratch to set up their servers, can for sure go for it.

    Well, the CentOS version series 7. x, which will receive updates until the regular end of support in June 2024, remains unaffected. CentOS 7.9 will therefore be the last edition to be created from the RHEL sources. The reason behind this is that still many companies relied on CentOS 7. Therefore, the CentOS developers do not want to stop the distribution prematurely.

    Whereas, as Redhat announced CentOS 8 will be available as a rolling distro in the form of Stream. Well, those are already using the Stream version, then maybe you want to get and test the CentOS 9 Stream available as an ISO file.

  • 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.
