1.下载oracle client rpm

Instant Client for Linux    http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64
oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64

这里下这两个就可以，然后安装

随即会在这个目录下生成.so的文件

/usr/lib/oracle/11.2/client64/lib

At this point, you‘re ready to register your newly-installed libraries:

2.配置phpize

下载的版本要和php版本一致，不然装不了

http://rpm.pbone.net/index.php3/stat/4/idpl/24668595/dir/scientific_linux_6/com/php-devel-5.3.3-26.el6.x86_64.rpm.html   

php-devel-5.3.3-26 x86_64 download

phpize，一种构建工具，为php扩展准备构建环境。

[root@ora11g tmp]# rpm -ivh php-devel-5.3.3-26.el6.x86_64.rpm

warning: php-devel-5.3.3-26.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY

   1:php-devel              ########################################### [100%]

[root@ora11g tmp]# whereis phpize

phpize: /usr/bin/phpize /usr/share/man/man1/phpize.1.gz

 3.配置oci8

 https://pecl.php.net/package/oci8   oci8下载

[root@ora11g oci]# cd

oci8-1.3.3/     oci8-1.3.3.tgz  package.xml    

[root@ora11g oci]# cd oci8-1.3.3

[root@ora11g oci8-1.3.3]# ls

config.m4   CREDITS  oci8_collection.c  oci8_interface.c  oci8_statement.c  php_oci8_int.h  tests

config.w32  oci8.c   oci8.dsp           oci8_lob.c        php_oci8.h        README

[root@ora11g oci8-1.3.3]# phpize

Configuring for:

PHP Api Version:         20090626

Zend Module Api No:      20090626

Zend Extension Api No:   220090626

When prompted, enter either the value of $ORACLE_HOME, or instantclient,/path/to/instant/client/lib.

Note: Do not enter the variable $ORACLE_HOME because it will not be expanded. Instead, enter the actual path of the Oracle home directory.

If using an RPM-based installation of Oracle Instant Client, the configure line will look like this:

./configure --with-oci8=shared,instantclient,/usr/lib/oracle/<version>/client/lib

For example, --with-oci8=shared,instantclient,/usr/lib/oracle/12.1/client/lib

Note that Oracle Instant Client support first appeared in PHP 4.3.11 and 5.0.4 and originally used the option --with-oci8-instant-client to configure PHP.

[root@ora11g oci8-1.3.3]# ./configure -with-oci8=shared,instantclient,/usr/lib/oracle/11.2/client64/lib

configure: creating ./config.status

config.status: creating config.h

config.status: executing libtool commands

make install

Libraries have been installed in:

   /tmp/oci/oci8-1.3.3/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/lib64/php/modules/

$echo extension=oci8.so > /etc/php.d/oci8.ini

$/etc/init.d/httpd restart

 oci8的安装官方文档参考如下：

http://php.net/manual/en/oci8.installation.php

 4.验证下php能否连上oracle数据库：

可以看到phpinfo中的信息oci8模块已经加载了 

[root@ora11g html]# more get_dbinfo.php
<?php
$db_connect = oci_connect(‘system‘, ‘xxx‘, ‘(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1
30.131)(PORT = 1521)) (CONNECT_DATA = http://www.mamicode.com/(SERVER = DEDICATED) (SERVICE_NAME = deff)))‘);

$sql_query = oci_parse($db_connect, ‘select status from v$instance‘);
oci_execute($sql_query,OCI_DEFAULT);
##echo $sql_query
while($r=oci_fetch_row($sql_query))
{
echo $r[0];
echo "<BR>";
}
?>
[root@ora11g html]# php get_dbinfo.php
OPEN<BR>[root@ora11g html]#

在这里，关于php的配置全部完成，后面就是关于一些php与数据库，与shell脚本相结合做出html界面的东西。
