Introduction
In this tutorial we learn how to install acme-tiny on CentOS 8.
What is acme-tiny
This is a tiny, auditable script that you can throw on your server to issue and renew Let’s Encrypt certificates. Since it has to be run on your server and have access to your private Let’s Encrypt account key, I tried to make it as tiny as possible (currently less than 200 lines). The only prerequisites are python and openssl. Well, that and a web server – but then you only need this with a web server. This package adds a simple directory layout and timer service that runs acme_tiny on installed CSRs as the acme user for privilege separation.
We can use yum or dnf to install acme-tiny on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install acme-tiny.
