  • How To Install Varnish on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install Varnish on AlmaLinux 8. For those of you who didn’t know, Varnish cache is an open-source, high-performance HTTP accelerator designed for speeding up web servers. Varnish exclusively focuses on HTTP as compared to other proxy servers which focus on FTP, SMTP, and other network protocols. It is purely designed to speed up caching of heavy dynamic websites.

If you’re a system admin, you must already know that the chgrp, chmod, and chown commands are the most powerful and most used terminal commands.

  • 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.
