Step-by-Step Guide to Setting Up BTCPay Server

1. Prepare Your Server

Start by setting up your VPS or dedicated server:

1. Update System Packages:
    

   sudo apt update && sudo apt upgrade -y
2. Install Required Tools:
    

   sudo apt install curl wget ufw -y

2. Install Docker and Docker Compose

BTCPay Server uses Docker to simplify deployment. Install Docker and Docker Compose:

1. Install Docker:
    

   curl -fsSL https://get.docker.com -o get-docker.sh sudo sh get-docker.sh
2. Install Docker Compose:
    

   sudo apt install docker-compose -y

3. Set Up a Domain Name

Point your domain name to your server's IP address:

1. Edit DNS Settings: Configure an A record in your DNS settings to point your domain to your server’s IP.
2. Verify DNS Propagation: Use a tool like WhatsMyDNS to ensure your domain points to the correct IP.

4. Deploy BTCPay Server

1. Clone the BTCPay Repository:

    

   git clone https://github.com/btcpayserver/btcpayserver-docker cd btcpayserver-docker

2. Set Up the Environment: Run the setup script to configure your BTCPay Server instance:

    

   ./btcpay-setup.sh -i

   You’ll be prompted to enter details like your domain name and whether to use HTTPS.

3. Start BTCPay Server:

    

   docker-compose up -d

5. Configure SSL for Secure Connections

BTCPay Server automatically sets up an SSL certificate using Let’s Encrypt if you provided a valid domain name. If not:

1. Install Certbot:
    

   sudo apt install certbot python3-certbot-nginx -y
2. Generate SSL Certificate:
    

   sudo certbot --nginx -d yourdomain.com
3. Restart Services:
    

   sudo systemctl restart nginx

6. Sync the Bitcoin Blockchain

To operate fully, BTCPay Server requires a synchronized Bitcoin node:

1. Access the BTCPay Server dashboard.
2. Navigate to the "Server Settings" > "Services" tab.
3. Enable the Bitcoin node synchronization.

This process may take several hours or days, depending on your server's performance.
