Telize is a REST API built on Nginx and Lua allowing to get a visitor IP address and to query location information from any IP address. It outputs JSON-encoded IP geolocation data, and supports both JSON and JSONP.
Geolocation operations are performed using Nginx GeoIP module which caches the database in RAM. Therefore, Telize has very minimal overhead and should be blazing fast.
Telize requires Nginx compiled with the following modules :
- GeoIP (Optional HTTP modules : --with-http_geoip_module)
- HttpRealipModule (Optional HTTP module : --with-http_realip_module)
- HttpEchoModule (Third party module (ngx_echo) : http://wiki.nginx.org/HttpEchoModule)
- HttpLuaModule (Third party module (ngx_lua) : http://wiki.nginx.org/HttpLuaModule)
- HttpHeadersMoreModule (Third party module (ngx_headers_more) : http://wiki.nginx.org/HttpHeadersMoreModule)
If you are using Debian stable, the nginx-extras package have these
modules compiled-in.
Telize requires the following Lua module :
- Lua CJSON
- Lua iconv
Installing via LuaRocks :
luarocks install lua-cjson
luarocks install lua-iconv
Telize requires the free GeoLite databases : http://dev.maxmind.com/geoip/legacy/geolite/
mkdir -p /usr/share/GeoIP
cd /usr/share/GeoIP
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
wget http://download.maxmind.com/download/geoip/database/asnum/GeoIPASNum.dat.gz
gunzip *gz
mkdir -p /usr/share/GeoIP
cd /usr/share/GeoIP
wget http://geolite.maxmind.com/download/geoip/database/GeoIPv6.dat.gz
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCityv6-beta/GeoLiteCityv6.dat.gz
wget http://download.maxmind.com/download/geoip/database/asnum/GeoIPASNumv6.dat.gz
gunzip *gz
Copy timezone.conf and timezone-offset.conf in the Nginx configuration files directory.
Edit nginx.conf to include timezone.conf, timezone-offset.conf and to add directives specifying the path to the GeoIP database files, within the http block.
http {
...
include /etc/nginx/timezone.conf;
include /etc/nginx/timezone-offset.conf;
geoip_country /usr/share/GeoIP/GeoIP.dat;
geoip_city /usr/share/GeoIP/GeoLiteCity.dat;
geoip_org /usr/share/GeoIP/GeoIPASNum.dat;
}
http {
...
include /etc/nginx/timezone.conf;
include /etc/nginx/timezone-offset.conf;
geoip_country /usr/share/GeoIP/GeoIPv6.dat;
geoip_city /usr/share/GeoIP/GeoLiteCityv6.dat;
geoip_org /usr/share/GeoIP/GeoIPASNumv6.dat;
}
Then deploy the API configuration file telize to the appropriate location on
your system, and reload Nginx configuration. If you are behind a load balancer, read the next section.
Depending on existing configuration, the map_hash_max_size and map_hash_bucket_size sizes might be set too low and Nginx will refuse to start. If this happens, please add the following directives in the http block.
map_hash_max_size 8192;
map_hash_bucket_size 64;
There is an automatic install script for Debian :
sh install/debian.sh
The default Telize configuration does not have logging enabled, it must be configured manually.
If your Telize instance produces lots of logs, this might be of interest : Log rotation directly within Nginx configuration file.
When using Telize behind a load balancer, uncomment the following directives in the server block and set the load balancer IP range accordingly :
# set_real_ip_from 10.0.0.0/8; # Put your load balancer IP range here
# real_ip_header X-Forwarded-For;
In the /geoip location, replace this directive :
proxy_set_header X-Real-IP $ip;
By the following directive :
proxy_set_header X-Forwarded-For $ip;
Telize has CORS enabled by default since version 1.02. The following variables defines CORS behavior, within the telize configuration file.
set $cors "true";
set $cors_origin "*";
For complete API documentation and JavaScript API usage examples, please check the project site : http://www.telize.com
- Example : http://www.telize.com/ip
- Example (JSON) : http://www.telize.com/jsonip
- Example (JSONP) : http://www.telize.com/jsonip?callback=getip
Calling the API endpoint without any parameter will return the visitor IP address :
- Example (JSON) : http://www.telize.com/geoip
- Example (JSONP) : http://www.telize.com/geoip?callback=getgeoip
Appending an IP address as parameter will return location information for this IP address :
- Example (JSON) : http://www.telize.com/geoip/46.19.37.108
- Example (JSONP) : http://www.telize.com/geoip/46.19.37.108?callback=getgeoip
