   若Centos安装提示没有程序包，请执行：
   rpm -ivh http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/6/i386/epel-release-6-8.noarch.rpm
   Cpanel中安装不成功请参考链接：

2. 案例
   

   <?php
       $countryArray =array(
           'USA'   //United States
           ,'GBR'   //United Kingdom
           ,'AUT'   //Australia
           ,'DEU'   //Germany
           ,'ITA'   //Italy
           ,'CAN'   //Canada
           ,'FRA'   //France
           ,'NZL'   //New Zealand
           ,'JPN'   //Japan
           ,'ESP'   //Spain
           ,'CHN'   //China
       );
       
       $fileName = $_GET['fileName'];
       if(isset($fileName)){
          $country_code = geoip_country_code3_by_name($_SERVER["REMOTE_ADDR"]);
   
         if(in_array($country_code, $countryArray))
            header("Location: http://www.google.com/".$fileName);
         else
            header("Location: http://www.baidu.com/".$fileName);
   }
   ?>

   保存上面的代码到PHP文件中，命令为file.php.
   访问：http://www.youwebsite.com/file.php?fileName=abc
   若访问的IP国家在CountryArray列表中，则链接跳转到：http://www.google.com/abc
   若不属于CountryArray列表，则链接到：http://www.baidu.com/abc

3. 验证geoip是否生效函数
   echo $_SERVER["REMOTE_ADDR"].'<br>';
   $country_code = geoip_country_code3_by_name($_SERVER["REMOTE_ADDR"]);
   $country_code = geoip_country_code3_by_name('58.186.0.0');
   echo $country_code.'<br>';
