首先到下载相关的文件，注意要连数据库服务器的版本，一定要对应，否则安装成功也会连不上，同时也要区分32位、64位服务器，比如我要连的数据库服务器是oracle10.2.0.4，64位主机，那么我要下载下面三个文件：

oracle-instantclient-basic-10.2.0.4-1.x86_64.rpm

oracle-instantclient-devel-10.2.0.4-1.x86_64.rpm

oracle-instantclient-sqlplus-10.2.0.4-1.x86_64.rpm

用以下命令安装

rpm -ivh oracle-instantclient-basic-10.2.0.4-1.x86_64.rpm oracle-instantclient-devel-10.2.0.4-1.x86_64.rpm    oracle-instantclient-sqlplus-10.2.0.4-1.x86_64.rpm

安装OCI8 PHP扩展

 

yum install libaio

cd ~

wget http://pecl.php.net/get/oci8-1.3.5.tgz

 

 

 

然后执行命令

tar zxvf oci8-1.3.5.tgz

cd oci8-1.3.5/

/usr/local/php5/bin/phpize  CFLAGS=/usr/lib/oracle/11.2/client64/ CXXFLAGS=/usr/lib/oracle/11.2/client64/

./configure --with-php-config=/usr/local/php5/bin/php-config --with-oci8=instantclient,/usr/lib/oracle/11.2/client64/lib/

 

make

make install(这里多运行几次,直到出现如下提示)

 

 

[root@webserver02 oci8-1.3.5]# make install

/bin/sh /root/oci8-1.3.5/libtool --mode=install cp ./oci8.la /root/oci8-1.3.5/modules

cp ./.libs/oci8.so /root/oci8-1.3.5/modules/oci8.so

cp ./.libs/oci8.lai /root/oci8-1.3.5/modules/oci8.la

PATH="$PATH:/sbin" ldconfig -n /root/oci8-1.3.5/modules

----------------------------------------------------------------------

Libraries have been installed in:

   /root/oci8-1.3.5/modules

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR'

flag during linking and do at least one of the following:

   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable

     during execution

   - add LIBDIR to the `LD_RUN_PATH' environment variable

     during linking

   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag

   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

----------------------------------------------------------------------

Installing shared extensions:     /usr/local/php5/lib/php/extensions/no-debug-zts-20090626/

cd /usr/local/php5/lib

创建ext目录

mkdir ext/

把oci8.so文件拷贝到php.ini 的ext目录里面

cp /root/oci8-1.3.5/modules/oci8.so /usr/local/php5/lib/ext/

 

 

在php.ini里面加上extension=oci8.so

如下:

 

extension_dir = "/usr/local/php5/lib/ext"

 

extension = "oci8.so"

 

session.save_path = "/tmp/php"

 

oci8.privileged_connect = on

 

 

重启apache服务:

/usr/local/apache2/bin/apachectl stop

/usr/local/apache2/bin/apachectl start

 

刷新测试页面。发现oci8出现了,则大功告成.
