It can be copied to your nginx module path manually if you wish. Add the following line to your nginx.conf: ``` load_module modules/ngx_http_geoip2_module.so; ``` ##### To build as a static module: ``` ./configure --add-module=/path/to/ngx_http_geoip2_module make make install ``` ##### If you need stream support, make sure to compile with stream: ``` ./configure --add-dynamic-module=/path/to/ngx_http_geoip2_module --with-stream OR ./configure --add-module=/path/to/ngx_http_geoip2_module --with-stream ``` ## Download Maxmind GeoLite2 Database (optional) The free GeoLite2 databases are available from [Maxminds website](http://dev.maxmind.com/geoip/geoip2/geolite2/) (requires signing up) ## Example Usage: ``` http { ... geoip2 /etc/maxmind-country.mmdb { auto_reload 5m; $geoip2_metadata_country_build metadata build_epoch; $geoip2_data_country_code default=US source=$variable_with_ip country iso_code; $geoip2_data_country_name country names en; } geoip2 /etc/maxmind-city.mmdb { $geoip2_data_city_name default=London city names en; } .... fastcgi_param COUNTRY_CODE $geoip2_data_country_code; fastcgi_param COUNTRY_NAME $geoip2_data_country_name; fastcgi_param CITY_NAME $geoip2_data_city_name; .... } stream { ... geoip2 /etc/maxmind-country.mmdb { $geoip2_data_country_code default=US source=$remote_addr country iso_code; } ... } ``` ##### Metadata: Retrieve metadata regarding the geoip database. ``` $variable_name metadata ``` Available fields: - build_epoch: the build timestamp of the maxmind database. - last_check: the last time the database was checked for changes (when using auto_reload) - last_change: the last time the database was reloaded (when using auto_reload) ##### Autoreload (default: disabled): Enabling auto reload will have nginx check the modification time of the database at the specified interval and reload it if it has changed. ``` auto_reload ``` ##### GeoIP: ``` $variable_name [default= "iso_code": "US" "names": { "de": "USA" "en": "United States" } } } $ mmdblookup --file /usr/share/GeoIP/GeoIP2-Country.mmdb --ip 8.8.8.8 country names en "United States" ``` This translates to: ``` $country_name "default=United States" source=$remote_addr country names en ``` ##### Additional Commands: These commands works the same as the original ngx_http_geoip_module documented here: http://nginx.org/en/docs/http/ngx_http_geoip_module.html#geoip_proxy. However, if you provide the `source=$variable_with_ip` option on a variable, these settings will be ignored for that particular variable. ``` geoip2_proxy < cidr > ``` Defines trusted addresses. When a request comes from a trusted address, an address from the "X-Forwarded-For" request header field will be used instead. ``` geoip2_proxy_recursive < on | off > ``` If recursive search is disabled then instead of the original client address that matches one of the trusted addresses, the last address sent in "X-Forwarded-For" will be used. If recursive search is enabled then instead of the original client address that matches one of the trusted addresses, the last non-trusted address sent in "X-Forwarded-For" will be used. ngx_http_geoip2_module-3.4/config000066400000000000000000000022571425451536200172320ustar00rootroot00000000000000ngx_feature="MaxmindDB library" ngx_feature_name= ngx_feature_run=no ngx_feature_incs="#include " ngx_feature_libs=-lmaxminddb ngx_feature_test="MMDB_s mmdb" . auto/feature ngx_addon_name="ngx_geoip2_module" if [ $ngx_found = yes ]; then if test -n "$ngx_module_link"; then if [ $HTTP != NO ]; then ngx_module_type=HTTP ngx_module_name="ngx_http_geoip2_module" ngx_module_incs= ngx_module_deps= ngx_module_srcs="$ngx_addon_dir/ngx_http_geoip2_module.c" ngx_module_libs="$ngx_feature_libs" . auto/module fi nginx_version=`awk '/^#define nginx_version / {print $3}' src/core/nginx.h` if [ $STREAM != NO -a $nginx_version -gt 1011001 ]; then ngx_module_type=STREAM ngx_module_name="ngx_stream_geoip2_module" ngx_module_incs= ngx_module_deps= ngx_module_srcs="$ngx_addon_dir/ngx_stream_geoip2_module.c" ngx_module_libs="$ngx_feature_libs" . auto/module fi else HTTP_MODULES="$HTTP_MODULES ngx_http_geoip2_module" NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_geoip2_module.c" CORE_LIBS="$CORE_LIBS $ngx_feature_libs" fi else cat << END $0: error: the geoip2 module requires the maxminddb library.
