Install nginx GeoIP2.

1. Run the installer

curl -fsSL https://mmdb.netcube.bg/apt/install.sh | sh

Run as root or a regular user. Root runs directly; otherwise authentication uses installed sudo, or falls back to su (root password). It never installs sudo. If neither is available, open a root shell (for example, su - where available) and rerun. Requires curl and an interactive terminal. This downloads and runs code as root: inspect the script first if you prefer.

It shows your installed nginx version and the proposed version, then asks [y/N]. Answer y to add both repositories and install or upgrade nginx with its matching module. Answer n to cancel.

• Missing prerequisites (python3, ca-certificates, gnupg) require manual installation. The bootstrap stops and prints an explicit APT command, even with --yes; it never installs prerequisites automatically.
• Existing nginx configuration is backed up under /var/backups/nginx-geoip2-*. Your nginx.conf and its existing include layout are preserved.
• Debian's standard nginx can be migrated after confirmation. Downgrades, unrelated removals, extra Debian modules and mixed source files are refused.
• No automatic service restart, cron job or client updater.

2. Enable the module when ready

Add this once at the top level of /etc/nginx/nginx.conf, before events and http:

load_module /usr/lib/nginx/modules/ngx_http_geoip2_module.so;

Configure your MMDB and GeoIP2 variables separately. Check configuration before your planned restart, especially after an nginx version change:

sudo nginx -t
# Only after a successful test, during your maintenance window:
sudo systemctl restart nginx

Existing workers may still run the old binary. A vendor migration may leave the service stopped; the installer deliberately does not restart it for you.

Updates are manual

sudo apt update
sudo apt upgrade

The module depends on an exact nginx version. Old module versions remain in the archive.
