Installing Free SSL for Nginx Reverse Proxy Domain

In this article, we learn about the procedure to install and configure free Let’s Encrypt SSL using certbot for a domain configured in nginx.

Install snap core (Ubuntu 22.04)

sudo snap install core; sudo snap refresh core

Install certbot using snap package

sudo snap install --classic certbot

Link certbot command, so you can just call it by typing certbot

sudo ln -s /snap/bin/certbot /usr/bin/certbot

To configure your nginx automatically with SSL use the below command

sudo certbot --nginx

This command will prompt automatically to select the site configured in nginx and the necessary code blocks including https redirect will be added automatically.

Otherwise, if you want to configure it manually, run the following command.

sudo certbot certonly --nginx
