Linux下PHP5.2 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

下载URL http://www.oracle.com/technetwork/indexes/downloads/index.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/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/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/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/php/etc/php.ini）

在extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"后增加一行：

extension = "oci8.so"

　　5、重启PHP

　　6、创建一个phpinfo.php文件（内容如下）并通过Web访问，如果有“oci8”这一项，则表明安装成功。

<?php

phpinfo();

?>

[root@localhost etc]# ulimit -SHn 65535

done

原来不是安装的问题，是linux下面自带的SELinux全称是Security Enhanced Linux在作怪，于是关掉它就ok了

[root@localhost etc]#

[root@localhost etc]# /usr/sbin/setenforce 0

使用php -m命令可以查看php是否已经装载了oci8模块

[root@localhost etc]#php -m | grep oci

oci8
