Installing PHP & Oracle PDO Drivers on Ubuntu

Given that PHP and Oracle databases are fairly mainstream platforms these days, you might expect that there would be a simple, straight-forward way to install and connect PHP with Oracle on Ubuntu.


If it’s not something you do regularly, or, unless you’ve got a fool-proof set of recent instructions, it is painful.

I faced the problem last week while configuring a a new virtual server. After a few hours of bumbling around I finally found a decent guide here for an earlier version of the Oracle instant client drivers. On the off-chance that it saves someone else some hassle, I thought I’d post a slight updated version that will work for PHP5.3 and Instant Client 11.2. Chances are that I’ll need to refer to this guide in the future, too.

I started with a brand-spanking new VM, running Ubuntu 12.04. Your mileage may vary if attempting to install over the top if earlier versions etc. You’ll need root privileges to run many of these commands, so you might want start a root shell (sudo su -).

First, fetch instant client and SDK packages from Oracle:
For 64bit Ubuntu, you’ll need to grab both “instantclient-basic-linux.x64-*.zip” and “instantclient-sdk-linux.x64-*.zip”.

Put both downloads somewhere convenient and extract:

mkdir -p /opt/oracle/instantclient
cp ~/instantclient-basic-*-*.zip /opt/oracle/instantclient/
cp ~/instantclient-sdk-*-*.zip /opt/oracle/instantclient/
cd /opt/oracle/instantclient
unzip ./instantclient-basic-*-*.zip
unzip ./instantclient-sdk-*-*.zip
mv instantclient*/* ./rmdir instantclient*/

Next, we need to create some symlinks so that the oracle shared libraries appear where they need to:

ln -s* libclntsh.soln -s*
echo /opt/oracle/instantclient >> /etc/

The following steps aren’t strictly necessary unless you need a TNS names config: You put the config details into sqlnet.ora file.

mkdir -p network/admin
touch network/admin/sqlnet.ora

Now install apache, php etc:

apt-get install --yes php5 php5-cli php5-dev php-db php-pear
apt-get install --yes build-essential libaio1

Install the pecl oci8 extension:

pecl install oci8

When prompted for the ORACLE_HOME path, enter “shared,instantclient,/opt/oracle/instantclient”

Add the configuration to your php.ini files:

echo "# configuration for php OCI8 module" > /etc/php5/cli/conf.d/oci8.ini
echo "" >> /etc/php5/cli/conf.d/oci8.ini

Now we install pdo_oci. It hasn’t been updated in a while so a few bits of fancy linking are in order…

cd /usr/include/
ln -s php5 php

cd /opt/oracle/instantclient

mkdir -p include/oracle/11.2/
cd include/oracle/11.2/
ln -s ../../../sdk/include client
cd –

mkdir -p lib/oracle/11.2/client
cd lib/oracle/11.2/client
ln -s ../../../../ lib
cd –

pecl channel-update
mkdir -p /tmp/pear/download/
cd /tmp/pear/download/
pecl download pdo_oci
tar xvf PDO_OCI*.tgz

### copy the lines below into the file “config.m4.patch”

./configure –with-pdo-oci=instantclient,/opt/oracle/instantclient,11.2

make && make test && make install && mv modules/ /usr/lib/php5/20090626/

Finally, add the configuration lines that enable the pdo_oci extension:

cat - < /etc/php5/apache2/conf.d/pdo_oci.ini# configuration for php PDO_OCI module

Check that everything succeeded:

php --info | grep oci
