环境是centos6 php5.2

yum -y install unixODBC-*

cd /data0/software/php-5.2.17/ext/pdo_odbc

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-odbc=unixODBC,/usr

make

make install

vi /usr/local/webserver/php/etc/php.ini 

extension = "pdo_odbc.so"

/usr/local/webserver/php/sbin/php-fpm restart

查看安装成功没？查找odbc
