我做了一个网站，它的一些子域名;根据国家的IP地址，该用户将被自动重定向到相应的子域。

I made a site it with some subdomains; according to the country's IP address the user is supposed to be automatically redirected to corresponding subdomain.

推荐答案

确认你有 mod_geoip 模块（< STRONG> GeoIP的扩展）安装到服务器上。

Check that you have the mod_geoip module (GeoIP Extension) installed on your server.

然后，调整你的的.htaccess 相应文件：

Then, tweak your .htaccess file accordingly :

GeoIPEnable On
GeoIPDBFile /path/to/GeoIP.dat

# Start Redirecting countries

# Canada
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^CA$
RewriteRule ^(.*)$ http://ca.abcd.com$1 [L]

# India
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^IN$
RewriteRule ^(.*)$ http://in.abcd.com$1 [L]

# etc etc etc...
