1.进入PHP源码包ext/pdo目录

cd ext/pdo

2.执行/usr/local/php/bin/phpize[假设PHP的安装目录为/usr/local/php]

 /usr/local/php/bin/phpize

3.配置扩展pdo

./configure --with-php-config=/usr/local/php/bin/php-config --enable-pdo=shared

4.编译安装pdo

make && make install

成功则出现

Installing shared extensions:     /usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/

Installing header files:          /usr/local/php//include/php/

Installing PDO headers:          /usr/local/php//include/php/ext/pdo/

说明在/usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/目录下生成了pdo.so文件

6.在php配置文件中加上

extension=”/usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/pdo.so”
