Finally, we need a DNS domain name: using No-IP tutorial steps, I will use my free “” as a test domain, where I will expose the Apache default index page. You also need to open/port forward port 443, as https protocol will use this port to work. We also need that our server can be reached on port 80 (with proper router port forwarding). For this purpose, I will use a standard LAMP installation on Raspberry PI. Step-by-Step Procedure Web Server and Domain PreparationĪs said, we need a running web page. You can inspect issued/revoked certificates publicly, making this extremely transparent. Let’s Encrypt also allows users to automate their service for most common web technologies, making painlessly all the process from obtaining a certificate, configuring it and renewing. Anyone who owns a domain name (even free, second-level domains) can use Let’s Encrypt to obtain a trusted certificate at zero cost. It aims to give common people a free way to get and maintain certificates in order to enable HTTPS (SSL/TLS) for their websites. Let’s Encrypt is a free Certification Authority provided by the Internet Security Research Group (ISRG). More details on how a certification process works can be found in my introduction to Self Signed Certificate tutorial. certbot works to issue and renew certificates automatically before their expiration. While Let’s Encrypt works as Certification Authority.

Let’s Encrypt and Certbot are 2 different pieces on securing your website. Please remember that webpage published on the internet need a public IP address (check my introduction to No-IP DUC installation). This can be useful to enhance security for your self hosted websites, like WordPress hosting on RPI, phpBB hosting on RPI or a simple LAMP server on RPI. In this post, I will show you how to install and configure Certbot on Raspberry PI with Apache to get your Let’s Encrypt free certificates working and renewed without manual intervention.
