Configure Nginx logs for your TierHive backend

Summary

You might have encounted an 10.0.0.x origin IP in your nginx logs.

Nginx webserver won't natively provide you with the origin IP as the VPS is "hidden" behind our HAProxy server. In that article we'll configure nginx webserver to collect the IP from the original request.

Real IP issue

Modify your /etc/nginx/nginx.conf file using vim or nano to add the following lines in the logging Settings section

    real_ip_header X-Forwarded-For;
    real_ip_recursive on;
    set_real_ip_from 10.0.0.0/24;

End result

/etc/nginx/nginx.conf:

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;

    real_ip_header X-Forwarded-For;
    real_ip_recursive on;
    set_real_ip_from 192.168.100.1/32;

Restart

Restart your nginx server

If you are using systemd:

systemctl restart nginx.service

if you are using openrc:

service nginx restart

if you are using openbsd:

rcctl restart nginx

Result

The screenshot above shows the origin IP from 10.0.0.3 (the haproxy server). Then after a nginx restart, the origin IP changed to the incoming IP starting by 7.
