The source tree is based on autotools to configure the building, and does also have the necessary bits in place to do functional unit tests using the varnishtest tool.
Install the GeoIP library headers:
apt-get install libgeoip-dev
To check out the current development source:
git clone git://github.com/lampeh/libvmod-geoip.git cd libvmod-geoip; ./autogen.sh
Usage:
./configure VARNISHSRC=DIR [VMODDIR=DIR]
VARNISHSRC is the directory of the Varnish source tree for which to compile your vmod. Both the VARNISHSRC and VARNISHSRC/include will be added to the include search paths for your module.
Optionally you can also set the vmod install directory by adding VMODDIR=DIR (defaults to the pkg-config discovered directory from your Varnish installation).
Make targets:
- make - builds the vmod
- make install - installs your vmod in VMODDIR
- make check - runs the unit tests in
src/tests/*.vtc
In your VCL you could then use this vmod along the following lines:
import geoip;
sub vcl_req {
# This sets req.http.X-Country-Code to the country code
# associated with the client IP address
set req.http.X-Country-Code = geoip.client_country_code();
}
