Get real IP Address

The front end is Nginx, the backend is apache,apache by default can only get the address of the front-end proxy IP, but sometimes need to get the real address, this time, we just need to add the RPAF module on the back-end Apache, and configure it.

wget http://stderr.net/apache/rpaf/download/mod_rpaf-0.6.tar.gz

TAR-XZVF mod_rpaf-0.6.tar.gz

CD mod_rpaf-0.6/

/usr/local/apache/bin/apxs-i-c-n Mod_rpaf-2.0.slo mod_rpaf-2.0.c

Add Apache Configuration

Vi/usr/local/apache/conf/httpd.conf

Include conf/extra/httpd-rpaf.conf

Vi/usr/local/apache/conf/extra/httpd-rpaf.conf

LoadModule Rpaf_module modules/mod_rpaf-2.0.so

Rpafenable on

Rpafsethostname on

Rpafproxy_ips 127.0.0.1 10.8.0.110 # Proxy Server IP address (remember to make corresponding changes)

Rpafheader x-forwarded-for

Check for errors in configuration and restart in effect

#/usr/local/apache/bin/apachectl-t

#/usr/local/apache/bin/apachectl Restart

Troubleshooting:

1. Check that the module is loaded successfully

Httpd-m

2. See if the front end has a configuration

3. See if you forgot to switch to Apache engine (change it in panel-to-system configuration)
