How to deny access to a site from USA but allow user-agent Googlebot?

Question

Nginx

All the best!
GNU/Linux Ubuntu 18.02 has LEMP installed (NGINX 1.14.0).

There is a need to block certain countries (for example, the USA and China), but allow access to the Google robot, which is located in the states.

How to write rules in NGINX configs so that using the NGINX GeoIP module you can block countries without catching certain user-agents?

Answer 1

map "$geoip_country_code,$http_user_agent" $deny {
    default           0;
    ~^US.*Googlebot   0;
    ~^US              1;
    ~^CN              1;
}

server {
    if ($deny) {
        return 403;
    }
