后勤的网站（彭同学做的）使用了pdo来操作数据库，服务器在配置是未编译pdo支持，遂给www服务器加上此功能的 支持。
一、先是在原有php5.2.9的基础上添加对pdo的支持，整了整整一天，也重新编译的php 5.2.9，最终没有成功
1.安装pdo
/usr/local/php/bin/pecl install pdo
2.安装pdo_mysql
wget http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz
tar xzvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config –with-pdo-mysql=/usr/local/mysql
make
make install
3.修改php.ini
加入：
extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/pdo.so
extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so
/usr/local/php/bin/php -v
PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib/php/modules//usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/pdo.so’ - /usr/lib/php/modules//usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0

二、下午下班回家决定升级php的版本，最后成功支持pdo。
1.下载php 5.2.13
2.安装
tar zxvf php*****
cd php**
./configure –prefix=/usr/local/php –with-apxs2=/usr/local/apache/bin/apxs –with-mysql=/usr/local/mysql/ –with-gd=/usr/local/gd/ –with-zlib-dir –with-png-dir –with-freetype-dir –with-jpeg-dir –enable-mbstring=all –with-curl –enable-pdo=shared \
–with-pdo-mysql=shared \
–with-sqlite=shared \
–with-pdo-sqlite=shared \
cp php.ini-dist /usr/local/php/lib/php.ini
3.修改php.ini
修改：
extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613″
加入：
extension=pdo.so
extension=pdo_mysql.so
4.查看http://*****/phpinfo.ini 看到对pdo的支持,ok!
