Installer le client Oracle pour PHP sur Centos 5.x

Si vous souhaitez utiliser une base de données depuis PHP sur une Centos 5.x, voilà la procédure à suivre.

On partira du principe que vous avez déjà installé PHP et apache.

Vous devez aussi installer les outils de développement afin de pouvoir compiler PECL:

yum -y groupinstall "development tools"

Sur le site d’oracle, télécharger les paquets suivants (en RPM):

oracle-instantclient11.2-basic
oracle-instantclient11.2-sqlplus (optionnel)
oracle-instantclient11.2-devel

Installer les paquets fraîchement téléchargés:

rpm -Uvh oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm oracle-instantclient11.2-devel-11.2.0.2.0.x86_64.rpm oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm

Il est nécessaire d’indiquer au système le chemin des nouvelles librairies:

echo "/usr/lib/oracle/11.2/client64/lib/" > /etc/ld.so.conf.d/oracle_lib.conf
ldconfig

Vous pouvez tester votre installation d’oracle en lançant /usr/bin/sqlplus64.

Ensuite on va installer OCI8 à l’aide de PECL:

Si vous passez par un proxy HTTP, configurez PECL comme suit:

pear config-set http_proxy http://proxy.xxx:3128

Lancez l’installation proprement dite.

pecl install oci8

L’installation se lance. A la question « Please provide the path to the ORACLE_HOME directory. Use ‘instantclient,/path/to/instant/client/lib’ if you’re compiling with Oracle Instant Client [autodetect] :« , donnez le chemin où est installé le client oracle, ici: instantclient,/usr/lib/oracle/11.2/client64/lib

You should add "extension=oci8.so" to php.ini

Comme indiqué, il faut maintenant configurer php pour utiliser le module OCI8.

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

redémarrez apache pour prendre en compte les modifications ( /etc/init.d/httpd restart ) . Vous pouvez vérifier la prise en compte d’OCI en utilisant la fonction PHP phpinfo();
