nginx reverse proxy IP

The issue with the wrong IP address being shown when using nginx as reverse proxy can easily be solved with mod_rpaf.

First one being my current home IP address, the second one being the nginx server IP address. The idea is to have the first line to show up in the logs.

On Gentoo (and I guess it’s fairly similar on other distributions);

Emerge it, add “-D RPAF” to /etc/conf.d/apache2 and add the following the the correct vhost (e.g. /etc/apache2/vhosts.d/your_vhost.conf):

<IfModule mod_rpaf.c>
      RPAFenable On
      RPAFsethostname On
      RPAFproxy_ips 85.12.6.171
</IfModule>

Change the bold IP address to your nginx rproxy IP address

Might be safe to run “apache2ctl configtest” to make sure you don’t have any errors in your config file(s).

And restart Apache. This makes it show the correct IP address in its log files.

Next on my to do list, getting it to actually cache something.
