1.安裝oracle的底層協議支持
rpm -ivh oracle-instantclient11.2-basic-11.2.0.2.0.i386.rpm
rpm -ivh oracle-instantclient11.2-devel-11.2.0.2.0.i386.rpm
oracle-instantclient可以到oracle的官方下載。我的系統是32位的，如果是64位系統請下載
oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpmoracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm
二、安裝php的相應擴展
oci8-1.4.10.tgz
1.tar zxvf oci8-1.4.10.tgz
2.cd oci8-1.4.10
3./usr/local/php/bin/phpize CFLAGS="-I/usr/include/oracle/11.2/client/" CXXFLAGS="-I/usr/include/oracle/11.2/client/"(注意：如果是64位的系統，client改成 client64)4../configure --with-php-config=/usr/local/php/bin/php-config --with-oci8=instantclient,/usr/lib/oracle/11.2/client/lib/
make
make install
cd /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
三、 修改php.ini 配置extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"extension = "pdo_mysql.so"extension = "oci8.so"
四、重啓apahce /或者nginx
