First Check Version of your Ubuntu

Run Command :  lsb_release -a

Distributor ID: Ubuntu
Description: Ubuntu 10.04.4 LTS
Release: 10.04
Codename: lucid

Pre Requisites:

sudo apt-get install build-essential
sudo apt-get install php5-dev php-pear libaio1

Instant Client installation requires some environment variables to be able to see the library folder. Edit /etc/environment and add at the end:

# Oracle Instant Client LD_LIBRARY_PATH=”/usr/local/lib/instantclient_12_1″ TNS_ADMIN=”/usr/local/lib/instantclient_12_1″ ORACLE_BASE=”/usr/local/lib/instantclient_12_1″ ORACLE_HOME=$ORACLE_BASE

Now Download Right Version of Oracle Install Client
32 Bit :

• Basic Version
• SDK Version

64 Bit

• Basic Version
• SDK Version

Now transfer the downloaded file from local pc to ubuntu server using WinSCP

• cd /usr/local/lib
• sudo unzip <location-of-instant-client-basic>
• sudo unzip <location-of-instant-client-sdk>
• cd instantclient_12_1
• sudo ln -s libclntsh.so.12.1 libclntsh.so

The symbolic link is needed during the compilation step later.

• sudo pecl install oci8

You will be prompted for the location of the library:

instantclient,/usr/local/lib/instantclient_12_1

PHP5 Instructions

You should now create a new oci8.ini file which will be included when loading php.ini (Editing the php.ini is discouraged):

nano /etc/php5/conf.d/oci8.ini

this will create a blank file; add to this file:

extension=oci8.so

In Ubuntu 13.10, you should create a new oci8.ini in:

nano /etc/php5/apache2/conf.d/oci8.ini

this will create a blank file. Then add to this file:

extension=oci8.so

Restart Apache

• sudo service apache2 restart

Check <?php echo phpinfo() ?> to verify if the oci8 module is available.

PHP Version 5.4.39-1+deb.sury.org~lucid+2
