Source: Internet
Author: User

Believe that have done awstats have used the open source Geoip.dat IP database, just nginx wiki on the GeoIP module, so that can achieve a regional load balance, but the Maxmind of IP database for China's support is not too good, but now is not bad ~
Reference article: Http://
Next to my environment, I have an American Linux server, an American Windows 2003, a local XP. Machine, other test users are, QQ group of friends, okay to start testing
Test forwarding, US user ~ forwarding to
Telecom forwarding to my one of the public network Apache default page
Netcom forwarded to my a public network service server!!
1. Download and install Nginx.
Shell $> Get
Shell $> Tar zxvf nginx-0.8.13.tar.gz
Shell $> CD nginx-0.8.13
Shell $>apt-get Install Libgeoip-dev
Shell $>./configure--prefix=/usr/local/nginx--with-http_flv_module--user=www--group=www--with-http_gzip_ Static_module--with-http_geoip_module
Shell $> Make
Shell $> make Install
2. Download the GeoLiteCity.dat.gz database ~
Shell $> wget
Shell $> gzip-d GeoLiteCity.dat.gz
Shell $> MV Geolitecity.dat/usr/local/nginx/conf/geolitecity.dat
3. Modify the configuration file to achieve a regional quality load
Shell $> cd/usr/local/nginx/conf
Shell $> Cat nginx.conf

4. Testing, using different local machines to do the test ~
I am a Beijing user, visit
I am a Beijing user access is the default page because I did not add 22 numbers to the configuration file. I was trying to make it easier! If you use it in production, you need to add 22 to
if ($geoip _region ~ "(05|08|09|10|12|17|18|19|20|24|25|26)")
No match to, access the default page ~ ~
Chengdu friends to help visit:
Guangzhou friends to help visit:
Hebei friends to help visit:
American Win2003 Visit:
Direct access to telecom servers and Netcom servers
59.151.x.x; 75.125.x.x;
Direct access to Netcom 59.151.x.x
Direct access to the telecom server 75.125.x.x
Let me explain.
if ($geoip _region ~ "(01|02|03|04|06|07|11|13|14|15|16|21|23|29|30|31|32|33)")
These figures represent the provinces of China ~ ~
The table is as follows:
cn,01, "Anhui."
cn,02, "Zhejiang."
cn,03, "Jiangxi."
cn,04, "Jiangsu."
cn,05, "Jilin."
cn,06, "Qinghai."

cn,29, "Yunnan."
cn,30, "Guangdong."
Cn,31, "Hainan."
cn,32, "Sichuan."
Cn,33, "Chongqing."
GeoLiteCity.dat More variables look at the wiki. I only use two variables here. One is the $geoip_region one is the $geoip_city_country the first is the region, the second is the country to take only two letters shorthand!
Syntax: geoip_city Path/to/db.dat;
Default: None
Context : http
The directive indicates the path to the "DAT file used for determining countries, regions and cities from ip-address of th E client. When set the module makes available the following variables:
$geoip _city_country_code; -Two-letter Country code, for example, "RU", "US". $geoip _city_country_code3; -Three-letter Country code, for example, "RUS", "USA". $geoip _city_country_name; -The name of the country, for example, "Russian Federation", "United States". $geoip _region; -The name of region (province, region, state, province, the federal land, and the like), for example, "Moscow City", "DC". $geoip _city; -The name of the city, for example, "Moscow", "Washington". $geoip _postal_code; -Postal code.
PS: I just according to the southern Telecom, North Netcom to distinguish ~ ~ I was a Beijing user access is the default page because I did not add 22 numbers to the configuration file. I was trying to make it easier! If you use it in production, you need to add 22 to
if ($geoip _region ~ "(05|08|09|10|12|17|18|19|20|24|25|26)")
Netcom ~ But open source GeoIP still some inaccurate ~ ~ ~ only to give him 75 points ~ ~
