Organising an internet utility within the cloud is at all times enjoyable and thrilling.
Lately I launched a Geekflare Instruments device, which is hosted in AWS behind Cloudflare.
I’m utilizing AWS utility load balancer and Nginx as internet server. After making it to life I went to the entry.log and noticed that every one requests have been marked as coming from inner (load balancer) IP.
This isn’t good if you wish to analyze your internet server logs for customer areas. I noticed that I’m lacking or must make some configuration adjustments to get better the shopper IP.
Are you in the identical scenario as me?
Effectively, here is methods to get the shopper IP in your Nginx entry logs.
Get customer IP from AWS or Google Cloud LB
- Login to your Nginx internet server
- Go to the trail the place it’s put in (default location /and many others/nginx)
- Again up
nginx.conffile - Add the next beneath HTTP Block
real_ip_header X-Forwarded-For;
set_real_ip_from 0.0.0.0/0;- Restart the Nginx and it’s best to see the customer’s IP tackle in your entry.log file
In case you’re behind Cloudflare, you may see their IP tackle as an alternative of the shopper’s IP tackle, so you may must do the under as nicely.
Get shopper IP from Cloudflare
Cloudflare is a good CDN and safety supplier, and I completely adore it. In case you use Cloudflare like me and need to get better the customer’s IP tackle within the internet server log, here is methods to do it.
Assuming you might be logged in to the Nginx server
Backup your web site’s configuration file (often right here – /and many others/nginx/sites-available/yourdomain)
Add the next to the start of the file
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 104.16.0.0/13;
set_real_ip_from 104.24.0.0/14;

set_real_ip_from 2a06:98c0::/29;
real_ip_header CF-Connecting-IP;Word: Chances are you’ll need to validate the IP checklist from their official web page.
Restart Nginx and it’s best to now see the shopper’s IP tackle. This helped me, and I hope you do too.
