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。

phpinfo();

?>

(1).

/usr/local/soft/oci8-1.3.5/oci8.c:3082: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'php_oci_ping_init'

make: *** [oci8.lo]

./configure --with-php-config=/usr/local/php/bin/php-config --with-oci8=shared,instantclient,/usr/lib/oracle/11.1/client/lib/

(2).

[root@localhost etc]# ulimit -SHn 65535

[root@localhost etc]# /usr/local/php/sbin/php-fpm restart

Shutting down php_fpm . done

Starting php_fpm PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/oci8.so' - /usr/lib/oracle/11.1/client/lib/libnnz11.so: cannot restore segment prot after reloc: Permission denied in Unknown on line 0

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
