Linux下PHP 5.2 Oracle客户端扩展（OCI8）安装

1、下载Oracle即时客户端程序包 — Basic：运行 OCI、OCCI 和 JDBC-OCI 应用程序所需的所有文件

①、打开以下网址（本文以32位版为例）：
（Linux 32位版）http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxsoft.html
（Linux 64位版）http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxx86_64soft.html

②、下载以下几个文件：
oracle-instantclient11.1-basic-11.1.0.7.0-1.i386.rpm
oracle-instantclient11.1-devel-11.1.0.7.0-1.i386.rpm
oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.i386.rpm
2、安装Oracle即时客户端程序包
rpm -ivh oracle-instantclient11.1-basic-11.1.0.7.0-1.i386.rpm oracle-instantclient11.1-devel-11.1.0.7.0-1.i386.rpm oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.i386.rpm
echo "/usr/lib/oracle/11.1/client/lib/" > /etc/ld.so.conf.d/oracle_client.conf
/sbin/ldconfig
3、安装OCI8 PHP扩展（使用PHP自带的OCI8，假设PHP程序安装在/usr/local/webserver/php/）
yum install libaio
wget http://pecl.php.net/get/oci8-1.3.5.tgz
tar zxvf oci8-1.3.5.tgz
cd oci8-1.3.5/
/usr/local/webserver/php/bin/phpize
CFLAGS="-I/usr/include/oracle/11.1/client/"
CXXFLAGS="-I/usr/include/oracle/11.1/client/"
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-oci8=/usr/lib/oracle/11.1/client/
make
make install
4、修改PHP配置文件（/usr/local/webserver/php/etc/php.ini）
在extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"后增加一行：
extension = "oci8.so"
5、重启PHP
