Hello, how to make setup with geoip2 .mmdb file. I want to run GeoIP2+Nginx+NginxLoadBalancer for tomcat country wise. My current file is

geoip2 /usr/share/GeoIP/GeoLite2-Country.mmdb{
$geoip2_data_country_code $upstream;
}

map $geoip2_data_country_code $upstream {
IN in_lb;
DE de_lb;
CA ca_lb;
}

upstream in_lb {
server 192.168.1.5:8080;
}

upstream de_lb {
server 192.168.5.10:8080;
}

upstream ca_lb {
server 192.168.10.10:8080;
}
server {
listen 80;
server_name my.domain.com;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-GeoIP-Country-Code $geoip2_data_country_code;
real_ip_header X-Forwarded-For;
proxy_pass http://$upstream;
}

}

Error: 500 Internal Server Error

Thanks @kmjones1979 for reply

Now I not going to set multi upstream here and main issue was in variables. New configurations working fine as below

geoip2 /usr/share/GeoIP/GeoLite2-Country.mmdb{
$geoip2_data_country_iso_code country iso_code;
}

map $geoip2_data_country_iso_code $upstream {
IN 192.168.1.5: (there is already load balancer working on 192.168.1.5 )
DE 192.168.5.10; (there is already load balancer working on 192.168.5.10)
}

It seems me good way, Is there any loop fall in this .conf ?

Hello, I am getting output "502 bad gateway" using below configuration. What may issue ? if I mentioned port with IP under upstream and and remove port in proxy_pass then its working but that will not fulfill my requirement. Actually there are running 5 tomcat with 5 different ports on single server like 172.16.1.5 only

upstream lb_ind {
server 172.16.1.5;
server 172.16.1.6;
}

upstream lb_france {
server 172.17.1.7;
}
geoip2 /usr/share/GeoIP/GeoLite2-Country.mmdb{
$geoip2_data_country_iso_code country iso_code;
}

map $geoip2_data_country_iso_code $itsupstream {
IN lb_ind;
DE lb_german;
CA lb_canada;
FR lb_france;
US lb_france;
}
server {
listen 80;
server_name my.domain.com;

            location /oauth2/ {
                    proxy_set_header    X-Real-IP $remote_addr;
                     proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header    X-Forwarded-Proto $scheme;
                    proxy_set_header    Host $host;
                    proxy_pass http://$itsupstream:8282$request_uri/;
            }

            location /producer/ {
                    proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header    X-Forwarded-Proto $scheme;
                     proxy_http_version 1.1;
                     proxy_set_header Upgrade $http_upgrade;
                     proxy_set_header Connection "upgrade";
                     proxy_set_header Host $host;
                    proxy_pass http://$itsupstream:8181$request_uri;
            }

    }
