Start HTTP server

With self-signed certificate (for testing)

Let's Encrypt is a free certificate authority: https://letsencrypt.org/
Use Certbot (free tool for automatically generatinging Let’s Encrypt certificates to enable HTTPS): https://certbot.eff.org/
- Install: dnf -y install certbot
Generate certificate: certbot certonly --standalone -d www.domain.com -d domain.com -m your.name@domain.com --agree-tos --no-eff-email
Copy certificate: cp /etc/letsencrypt/live/domain.com/fullchain.pem ./cert/cert.pem
Copy private key: cp /etc/letsencrypt/live/domain.com/privkey.pem ./cert/key.pem
Or use your web server for challenge exchange: certbot certonly --webroot -w ./ -d domain.com -m your.name@domain.com --agree-tos --no-eff-email
