    sudo dpkg -i packages-microsoft-prod.deb
    sudo apt-get install apt-transport-https
    sudo apt-get update
    sudo apt-get install -y dotnet-sdk-3.1

    git clone https://github.com/dgarage/NBXplorer
    cd NBXplorer
    ./build.sh
    vim ~/.nbxplorer/Main/settings.config
   
    # Add RPC username password:
    btc.rpc.user=username
    btc.rpc.password=password
   
    nohup ./run.sh > out.log &
   

3. Install and run BTCPayServer

    git clone https://github.com/btcpayserver/btcpayserver
    cd btcpayserver
    ./build.sh
   
    # By default lnd binds to 8080, so use 8081
    nohup ./run.sh --port 8081 --bind 0.0.0.0 > out.log &
   

4. Install LetsEncrypt cert:

   wget https://raw.githubusercontent.com/janoside/bitcoin-resources/master/files/btcpay-nginx-config.txt
   mv btcpay-nginx-config.txt /etc/nginx/sites-available/btcpay.btc21.org
   cd /etc/nginx/sites-enabled/
   ln -s ../sites-available/btcpay.btc21.org .
   service nginx restart
   certbot --nginx -d btcpay.btc21.org
   service nginx restart
   

Optional:

If you're running LND - configure a store and go to its settings and down to Lightning Nodes

# get admin macaroon hex
xxd -plain /root/.lnd/data/chain/bitcoin/mainnet/admin.macaroon | tr -d '\n'

# get cert thumbprint
openssl x509 -noout -fingerprint -sha256 -in /root/.lnd/tls.cert | sed -e 's/.*=//;s/://g'

Then configure the lightning node with:

type=lnd-rest;server=https://127.0.0.1:8080/;macaroon=MACAROON_HEX;certthumbprint=CERT_THUMBPRINT

Optional:

vim /etc/systemd/system/nbexplorer.service
sudo systemctl enable nbxplorer.service
sudo service nbxplorer start
sudo service nbxplorer status

vim /etc/systemd/system/btcpayserver.service
sudo systemctl enable btcpayserver.service
