To get your Public Key Pin base-64 encoded fingerprint, use the command below and replace the Public-Key-Pins header info with the output from this command.

openssl rsa -in /etc/pki/tls/private/example_com_no_pass.key -outform der -pubout | openssl dgst -sha256 -binary | openssl enc -base64

Note that Public Key Pins can cause problems if you need to revoke your cert and you don't have more than one cert pinned (IE a backup cert). For this reason, I recommend against it.

To get your dhparams.pem file, you run one command

openssl dhparam -out /etc/pki/tls/certs/dhparams.pem 2048

To setup a reverse proxy instead of serving HTML, change the location section in the above config to this:

location / {
    proxy_pass https://<your_domain>.com;
    proxy_set_header Host <your_domain>.com;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
