Install mod_rpaf on CentOS 5, CentOS 6

This is a quick guide on how to install mod_rpaf on CentOS 5 and CentOS 6. (This guide can also be used to install mod_rpaf on RHEL and Fedora Core)

1. Retrieve and Extract mod_rpaf packages:

# cd /usr/local/src
# 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

2. Build and install mod_rpaf

# apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c

[ httpd-devel is the package required to run apxs ]

3. Add mod_rpaf to Apache configuration

# vim /etc/httpd/conf/httpd.conf

— Find the “LoadModule” list (near the top)
— Add the following lines at the bottom of the “LoadModule” list:

LoadModule rpaf_module modules/mod_rpaf-2.0.so

# mod_rpaf Configuration

RPAFenable On
RPAFsethostname On
RPAFproxy_ips 127.0.0.1 10.0.0.1
RPAFheader X-Forwarded-For

Important: Where “127.0.0.1 10.0.0.1″ is, add your proxy server IP address(es). This will tell mod_rpaf which hosts to get X-Forwarded-For headers from.

4. Finish

Restart Apache for the changes to take effect

/etc/init.d/httpd restart

5. Troubleshooting

The following dependencies may need to be installed before installing mod_rpaf:

httpd-devel, gcc

They can be installed using the following commands:

yum install httpd-devel gcc
