Make sure to install nginx before generating an SSL certificate using Certbot, as Certbot can automatically install the certificate and make all the required configurations on nginx. This guide makes use of that functionality.
Certbot - SSL Certificate
Having an SSL certificate ensures a secured connection between users and the server, and that no data is compromised while it is traveling over the internet. This allows users to connect using HTTPS protocol over the port 443.
This guide assumes the server already has a domain and the necessary DNS record/s have been created.
Open ports 80 and 443, belonging to HTTP and HTTPS respectively. Port 22 is also required.
Connect via SSH to the server with a user with sudo privileges.
Install Certbot
sudo snap install --classic certbotPrepare the Certbot command
sudo ln -s /snap/bin/certbot /usr/bin/certbotGenerate the certificate, this will also automatically edit the nginx configuration to serve it.
sudo certbot --nginxCertbot will ask some questions, like an email to send notifications about certificate renewals.
After the initial questions, Certbot will ask for the domain names to issue the certificate. It will try to access the server over port 80 using the domain name, so it’s imperative the DNS records are already configured.
Test that Certbot is capable of renewing the certificate, otherwise after a couple of months it will expire and users will lose access to the services.
Renewal succeeded output.

Nginx Configuration
NiFi by default runs on port 8443, similarly, Superset runs on port 8088. However, to have a secured connection users should only be able to connect through port 443, where the SSL certificate is served.
Nginx will act as a reverse-proxy and redirect users requests that come through port 443 to the correct destinations.
Nginx configuration file can be edited using the following command:
Search for the server bracket that is listening to port 443. Certbot configuration can be found here.
Edit and add the locations to redirect traffic.
The above configuration will make Moodle accessible by using the base domain (https://exampledomain.com)
