  • How to Limit Network Bandwidth in NGINX Web Server

    Previously, in our NGINX traffic management and security controls series, we have discussed how to limit the number of connections the same client can make to your web resources, using client identification parameters such as IP address. We also covered how to limit the rate of requests (limit the rate at which a client can make requests) for your web resources.

    To ensure that your application usage bandwidth is not expended by a single client, you need to control the upload and download speeds per client. This is a common NGINX security control against DoS (Denial of Service) attacks from malicious users who are just trying to abuse site performance.

    In this third part of the series, we will explain how to limit network bandwidth in the NGINX web server.

  • 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.

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.

  • 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.
