Install LetsEncrypt SSL for Faveo on Ubuntu 20.04 and 22.04 Running Nginx Web Server

Introduction

This document will list on how to install LetsEncrypt SSL on Ubuntu Running Nginx Web Server

PS : Please replace example.com with your valid domain name which is mapped with your server

We will install following dependencies in order to make LetsEncrypt SSL work:

apt install python3-certbot-nginx -y

Certbot will handle the SSL certificate management quite easily, it will generate a new certificate for provided domain as a parameter.

In this case, example.com will be used as the domain for which the certificate will be issued:

certbot --nginx -d example.com

If you want to generate SSL for multiple domains or subdomains, please run this command:

certbot --nginx -d example.com -d www.example.com

PS : IMPORTANT! The first domain should be your base domain, in this sample it’s example.com

Create new cron job for automatic renewal of SSL

This job can be safely scheduled to run every Monday at midnight:

Create a new /etc/cron.d/faveo-ssl file with:

echo "45 2 * * 6 /etc/letsencrypt/ && ./certbot renew && /bin/systemctl restart nginx" | sudo tee /etc/cron.d/faveo-ssl
