Create nginx reverse proxy service

I created a script to create a reverse proxy service for nginx. The script is based on https://docs.btcpayserver.org/Deployment/ReverseProxyToTor. The script assumes a Debian-based system and will use certbot to obtain a certificate and upgrade HTTP connections to HTTPS.

Requirements

  • Debian system
  • Domain record configured
  • Root access
  • HTTP or HTTPS service to be proxied

Usage

  1. View the script, create_nginx_service.sh and make sure you're comfortable with what it's doing

  2. Download the script

     wget https://raw.githubusercontent.com/sudocarlos/sudocarlos.com/main/create_nginx_service.sh

  3. Make the script executable

     chmod +x create_nginx_service.sh

  4. Run the script as root and specify the domain and address/port to proxy to

     sudo ./create_nginx_service.sh btcpayserver.mydomain.com http://localhost:80

    More examples

     sudo ./create_nginx_service.sh mymempooldomain.com http://start9:8080
 sudo ./create_nginx_service.sh lnd.mydomain.com https://start9:3001

Notes

  • All issuance requests are subject to a Duplicate Certificate limit of 5 per week
  • Use sudo ./create_nginx_service.sh clear DOMAIN to remove related files from your system. This will remove:
    • /etc/nginx/sites-available/DOMAIN.conf
    • /etc/nginx/sites-enabled/DOMAIN.conf
    • /etc/letsencrypt/live/DOMAIN*
    • /etc/letsencrypt/archive/DOMAIN*
    • /etc/letsencrypt/renewal/DOMAIN*
  • If nginx or certbot are not installed, they are installed using apt
  • If /etc/ssl/certs/dhparam.pem does not exist, a 4096 bit DH params is generated. This can take a while.
  • If /var/lib/letsencrypt/.well-known does not exist, it is created and appropriate permissions and groups are applied
  • If expected map parameters are missing from /etc/nginx/conf.d/map.conf, they are added
  • New configs are placed in /etc/nginx/sites-available/ and enabled in /etc/nginx/sites-enabled
