Installing mod_geoip For Lighttpd On Debian Etch - Page 3

2.2 lighttpd 1.5.x

First, install all prerequisites:

apt-get install build-essential dpkg-dev fakeroot debhelper cdbs libssl-dev zlib1g-dev libbz2-dev libattr1-dev libpcre3-dev libmysqlclient15-dev libldap2-dev libfcgi-dev libgdbm-dev libmemcache-dev liblua5.1-0-dev dpatch patchutils pkg-config uuid-dev libsqlite3-dev libxml2-dev automake libtool libgeoip1 libgeoip-dev libglib2.0-dev libglib2.0-0

Then download the lighttpd sources that match your installed lighttpd, e.g. lighttpd-1.5.0-r1992:

cd /usr/local/src/
wget http://www.lighttpd.net/download/lighttpd-1.5.0-r1992.tar.gz
tar -xzf lighttpd-1.5.0-r1992.tar.gz

cd lighttpd-1.5.0/src
wget -O mod_geoip.c http://trac.lighttpd.net/trac/attachment/wiki/Docs/ModGeoip/mod_geoip.4.c?format=raw

Now open Makefile.am and after the last lib_LTLIBRARIES stanza (should be the lib_LTLIBRARIES += mod_accesslog.la stanza), add the following stanza:

vi Makefile.am

[...]
lib_LTLIBRARIES += mod_geoip.la
mod_geoip_la_SOURCES = mod_geoip.c
mod_geoip_la_LDFLAGS = -module -export-dynamic -avoid-version -no-undefined
mod_geoip_la_LIBADD = $(common_libadd) -lGeoIP
[...]

It should look like this:

[...]
lib_LTLIBRARIES += mod_accesslog.la
mod_accesslog_la_SOURCES = mod_accesslog.c
mod_accesslog_la_LDFLAGS = -module -export-dynamic -avoid-version -no-undefined
mod_accesslog_la_LIBADD = $(common_libadd)

lib_LTLIBRARIES += mod_geoip.la
mod_geoip_la_SOURCES = mod_geoip.c
mod_geoip_la_LDFLAGS = -module -export-dynamic -avoid-version -no-undefined
mod_geoip_la_LIBADD = $(common_libadd) -lGeoIP

[...]

Next do this:

cd ..
aclocal && automake -a && autoconf

./configure --with-linux-aio --libdir=/usr/lib/lighttpd --sbindir=/usr/sbin --with-openssl --with-pcre --with-bz2 --with-ldap --with-mysql --with-memcache --with-lua=lua5.1 --with-gdbm --with-attr --with-webdav-locks --with-webdav-props
make

After the make command has succesfully finished, you should find mod_geoip.so in the /usr/local/src/lighttpd-1.5.0/src/.libs directory. This is all we need so we don't need to run make install. We can continue to use our old lighttpd installation and simply copy mod_geoip.so to the directory which contains our lighttpd modules (e.g. /usr/lib/lighttpd):

cp /usr/local/src/lighttpd-1.5.0/src/.libs/mod_geoip.so /usr/lib/lighttpd

Now we must configure lighttpd to use mod_geoip. First, we download the GeoIP country database:

mkdir /usr/local/data
cd /usr/local/data
wget http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz
gunzip GeoIP.dat.gz

Then open /etc/lighttpd/lighttpd.conf and add "mod_geoip", to the server.modules section; also add the geoip.db-filename and geoip.memory-cache directives below the server.modules section:

vi /etc/lighttpd/lighttpd.conf

[...]
server.modules              = (
            "mod_access",
            "mod_alias",
            "mod_accesslog",
            "mod_geoip",
            "mod_fastcgi",
#           "mod_rewrite",
#           "mod_redirect",
#           "mod_status",
#           "mod_evhost",
#           "mod_compress",
#           "mod_usertrack",
#           "mod_rrdtool",
#           "mod_webdav",
#           "mod_expire",
#           "mod_flv_streaming",
#           "mod_evasive"
 )

geoip.db-filename = "/usr/local/data/GeoIP.dat"
geoip.memory-cache = "enable"
[...]

Restart lighttpd:

/etc/init.d/lighttpd restart

To see if mod_geoip is working correctly, we can create a small PHP file in one of our web spaces (e.g. /var/www) (of course, PHP must be enabled in your lighttpd installation):

vi /var/www/geoiptest.php

<?php
print_r($_SERVER);
?>

Call that file in a browser, and it should display the SERVER array including values for GEOIP_COUNTRY_CODE, GEOIP_COUNTRY_CODE3, and GEOIP_COUNTRY_NAME (make sure that you're calling the file from a public IP address, not a local one).

If you want to use lighttpd + mod_geoip for your OpenX ad server, make sure you select MaxMind mod_apache GeoIP under Settings > Main Settings > Geotargeting Settings. This will work for lighttod + mod_geoip as well.
