MaxMind DB Apache Module

This module allows you to query MaxMind DB files from Apache 2.2+ using the libmaxminddb library.


This module requires Apache 2.2 or 2.4 to be installed, including any corresponding “dev” package, such as apache2-dev on Ubuntu. You should have apxs or apxs2 in your $PATH.

You also must install the libmaxminddb C library.


To install the module from a tarball, run the following commands from the directory with the extracted source:

make install

To use another Apache installation, specify a path to the right apxs binary:

./configure --with-apxs=/foo/bar/apxs

If you are compiling the module from a Git checkout, you must have automake, autoconf, and libtool installed and you must run ./bootstrap before running configure.


To use this module, you must first download or create a MaxMind DB file. We provide free GeoLite2 databases as well as commercial GeoIP2 databases.

After installing this module and obtaining a database, you must now set up the module in your Apache configuration file (e.g., /etc/apache2/apache2.conf) or in an .htaccess file. You must set MaxMindDBEnable to enable the module, MaxMindDBFile to specify the database to use, and MaxMindDBEnv to bind the desired lookup result to an environment variable.

This module uses the client IP address for the lookup. This is not always what you want. If you need to use an IP address specified in a header (e.g., by your proxy frontend), mod_remoteip may be used to set the client IP address.


All directives may appear either in your server configuration or an .htaccess file. Directives in <Location> and <Directory> blocks will also apply to sub-locations and subdirectories. The configuration will be merged with the most specific taking precedence. For instance, a conflicting directive set for a subdirectory will be used for the subdirectory rather than the directive set for the parent location.

Similarly, the main server configuration may set defaults that will be merged into the configuration provided by individual virtual hosts. However, please note that currently no configuration merging is performed between server/vhost and directory configurations.


This directive enables or disables the MaxMind DB lookup. Valid settings are On and Off.

MaxMindDBEnable On


This directive associates a name placeholder with a MaxMind DB file on the disk. You may specify multiple databases, each with its own name.

MaxMindDBFile COUNTRY_DB /usr/local/share/GeoIP/GeoLite2-Country.mmdb
MaxMindDBFile CITY_DB    /usr/local/share/GeoIP/GeoLite2-City.mmdb

The name placeholder can be any string that Apache parses as a word. We recommend sticking to letters, numbers, and underscores.


This directive assigns the lookup result to an environment variable. The first parameter after the directive is the environment variable. The second parameter is the name of the database followed by the path to the desired data using map keys or 0-based array indexes separated by /.

MaxMindDBEnv COUNTRY_CODE COUNTRY_DB/country/iso_code
MaxMindDBEnv REGION_CODE  CITY_DB/subdivisions/0/iso_code

Exported Environment Variables

In addition to the environment variable specified by MaxMindDBEnv, this module exports MMDB_ADDR, which contains the IP address used for lookups by the module. This is primarily intended for debugging purposes.


City Database

<IfModule mod_maxminddb.c>
    MaxMindDBEnable On
    MaxMindDBFile CITY_DB /usr/local/share/GeoIP/GeoLite2-City.mmdb

    MaxMindDBEnv MM_COUNTRY_CODE CITY_DB/country/iso_code
    MaxMindDBEnv MM_COUNTRY_NAME CITY_DB/country/names/en
    MaxMindDBEnv MM_CITY_NAME CITY_DB/city/names/en
    MaxMindDBEnv MM_LONGITUDE CITY_DB/location/longitude
    MaxMindDBEnv MM_LATITUDE CITY_DB/location/latitude

Connection-Type Database

<IfModule mod_maxminddb.c>
    MaxMindDBEnable On
    MaxMindDBFile CONNECTION_TYPE_DB /usr/local/share/GeoIP/GeoIP2-Connection-Type.mmdb


Domain Database

<IfModule mod_maxminddb.c>
    MaxMindDBEnable On
    MaxMindDBFile DOMAIN_DB /usr/local/share/GeoIP/GeoIP2-Domain.mmdb

    MaxMindDBEnv MM_DOMAIN DOMAIN_DB/domain

ISP Database

<IfModule mod_maxminddb.c>
    MaxMindDBEnable On
    MaxMindDBFile ISP_DB /usr/local/share/GeoIP/GeoIP2-ISP.mmdb

    MaxMindDBEnv MM_ASN ISP_DB/autonomous_system_number
    MaxMindDBEnv MM_ASORG ISP_DB/autonomous_system_organization
    MaxMindDBEnv MM_ISP ISP_DB/isp
    MaxMindDBEnv MM_ORG ISP_DB/organization

Blocking by Country

This example shows how to block users based on their country:

MaxMindDBEnable On
MaxMindDBFile DB /usr/local/share/GeoIP/GeoLite2-Country.mmdb
MaxMindDBEnv MM_COUNTRY_CODE DB/country/iso_code

SetEnvIf MM_COUNTRY_CODE ^(RU|DE|FR) BlockCountry
Deny from env=BlockCountry

Data Output Format

All data is provided as a string bound to the specified Apache environment variable. Floating point numbers are provided to five digits after the decimal place. All integers types except 128-bit integers are provided as decimal. 128-bit integers are returned as hexadecimal. Booleans are returned as “0” for false and “1” for true.

Note that data stored as the “bytes” type in a MaxMind DB database can contain null bytes and may end up truncated when stored in an environment variable. If you really need to access this data, we recommend using one of our programming language APIs instead.
