Nginx will serve several important functions:
Connect to the server with the SSH connection script.
Open Nginx configuration.
sudo nano /etc/nginx/nginx.conf
Add configuration to the http section, before #Basic Settings. Server_name should be the URL of your server followed by the IP of your server. Ssl_certificate should point to your chained certificate file.
Save and close the nano text editor: ctrl+o, ctrl+x.
sudo nginx -t -c /etc/nginx/nginx.conf
sudo service nginx restart
Exit the SSH session.
Test the SSL certificate with SSL Checker from Website Planet.
