  • How to set up a CrowdSec multi-server installation | Linux Journal

    CrowdSec is an open-source & collaborative security solution built to secure Internet-exposed Linux services, servers, containers, or virtual machines with a server-side agent. It is a modernized version of Fail2ban which was a great source of inspiration to the project founders.

    CrowdSec is free (under an MIT License) and its source code available on GitHub. The solution is leveraging a log-based IP behavior analysis engine to detect attacks. When the CrowdSec agent detects any aggression, it offers different types of remediation to deal with the IP behind it (access prohibition, captcha, 2FA authentication etc.). The report is curated by the platform and, if legitimate, shared across the CrowdSec community so users can also protect their assets from this IP address.

    A few months ago, we added some interesting features to CrowdSec when releasing v1.0.x. One of the most exciting ones is the ability of the CrowdSec agent to act as an HTTP rest API to collect signals from other CrowdSec agents. Thus, it is the responsibility of this special agent to store and share the collected signals. We will call this special agent the LAPI server from now on.

  • 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.
