Installation of mod_rpaf on CentOS from Source

The below instructions can be used to install mod_rpaf on CentOS 5 and CentOS 6. It can also be used to install mod_rpaf on RHEL and Fedora Core.

Note: You must make sure that the Apache2 Development Package (CentOS httpd-devel) is installed on your server before you start installing mod_rpaf using the below instructions.

1. Ensure that the package 

   httpd-devel

    is installed. To install this package run:

   <code>yum install httpd-devel </code>

2. Download and Extract the mod_rpaf package:

   <code>cd /usr/local/src wget http://mirror.trouble-free.net/sources/mod_rpaf-0.6.tar.gz tar xzvf mod_rpaf-0.6.tar.gz cd mod_rpaf-0.6 </code>

3. Build and install mod_rpaf:

   <code>apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c </code>

4. Add mod_rpaf to Apache configuration:

   <code>nano /etc/httpd/conf/httpd.conf </code>

5. Find the 'LoadModule' list (near the top) and add the following lines at the bottom of the 'LoadModule' list:

   <code>LoadModule rpaf_module modules/mod_rpaf-2.0.so RPAFenable On RPAFsethostname On RPAFproxy_ips 127.0.0.1 A.B.C.D RPAFheader X-Real-IP </code>

   Important Note: Where «A.B.C.D» is, add your proxy server IP address(es), multiple addresses can be space separated. This will tell mod_rpaf which hosts to get X-Real-IP headers from.

6. You are now finished. Restart Apache using below commands for the changes to take place:

   <code>/etc/init.d/httpd restart</code>
