  • How to install and use Firewalld on Rocky Linux 8 - Linux Shout

    Firewalls are one of the most essential parts of security when we are going online. Here we learn the steps and command to install, configure, and how to use FirewallD on Rocky Linux 8 using CLI or GUI.

    Many of us who are not already Linux would already be familiar with the firewall feature on Windows, where it is very easy to turn On or Off ports or services using GUI. However, what about Linux such as CentOS, Rocky Linux, RedHat, AlmaLinux, and more… If you are using full Linux Desktop then a firewall would already be there but in most of the cases without a graphical interface. Nevertheless, Debian, RedHat, Ubuntu, and other Linux systems provide the appropriate firewall GUI software directly from their respective repository to manage things with the help of mouse clicks.

    But what if you just want a basic OS installation with no graphical interface? Because minimal versions of Linux would not even have the CLI version of Firewall by default. Well, this is a very small problem, if you have an active internet connection and due to an in-built package manager under Linux, we can install a firewall with just a single command.

  • 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.
