QQWry 是一个php扩展，这个扩展的作用，就是根据ip来获取纯真数据库(QQWry.Dat)的地址信息。我们通常使用pecl来安装qqwry，我们安装pecl需要安装pear。pear是PHP扩展与应用库，它是一个PHP扩展与应用的一个仓库。

我们先来安装pear：

1.http://pear.php.net/go-pear.phar下载最新的go-pear。

  #php go-pear.phar

2.至此，pear安装完毕，我们就可以安装qqwry了。

 #pecl install qqwry-beta

  修改php配置文件，将该模块写入。

  #vim /etc/php.ini

  extension=qqwry.so

3.qqwry就安装好了，这时需要重启httpd服务。

  #service httpd restart
