#StackBounty: #nginx #apache-2.4 #proxy nginx proxy to apache – Remote IP not recorded

Bounty: 50

I have nginx terminating websites and proxying them to Apache with PHP-FPM. I’m trying to record the Clients IP in the apache log, but cannot seem to get this to work.

nginx configuration

server {
  listen         80;
  server_name    www.website.com;

  location ^~ /.well-known/acme-challenge/ {
      alias /var/www/dehydrated/;
  }

  location / {
      return         301 https://$server_name$request_uri;
  }
}

server {
  listen 443 ssl http2;
  server_name www.website.com;

  location / {
      proxy_pass http://1.2.3.4:80;
      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-Forwarded-Proto $scheme;
      proxy_read_timeout 600;
      proxy_buffer_size   128k;
      proxy_buffers   4 256k;
      proxy_busy_buffers_size   256k;
      client_max_body_size 100M;
  }

  location ~ /.ht {
      deny all;
  }

  ssl_prefer_server_ciphers on;
  ssl_dhparam /etc/nginx/ssl/dhparams.pem;
}

apache configuration

  <VirtualHost *:80>

    ServerName www.website.com
    ServerAlias origin.www.website.com

    ServerAdmin jd@automatem.co.nz

    DocumentRoot /var/www/www.website.com/trunk

    <IfModule mpm_itk_module>
          AssignUserId www_arenz www_arenz
    </IfModule>
    CustomLog /var/www/www.website.com/apachelogs/www.website.com-access.log combined
    ErrorLog /var/www/www.website.com/apachelogs/www.website.com-error.log

      <FilesMatch ".php$">
          CGIPassAuth on
          SetHandler "proxy:fcgi://127.0.0.1:9115/
      </FilesMatch>

      RemoteIPHeader X-Real-IP
      RemoteIPTrustedProxy 2.3.4.5/32


  </VirtualHost>

Apache logs always show 2.3.4.5 as the IP address of the client, which is the public IP address of nginx
