Our developers had to have OCI.  Now that I got that out of the way. 😉

We use Oracle as our DB for most applications (calm down, like you couldn’t have figured that out).  In setting up a new application server for a custom application it came to my attention that the application used oci calls.  What a pain to get working on Red Hat!  There is a ton of documentation for Oracle Linux, but that wasn’t an option.  So here is what I had to do to get things working.

yum install php-pecl-apc php-pear gcc php-devel glibc glibc-devel

rpm -iv oracle-instantclient11.2-basic- 
pear download pecl/oci8
tar -xvzf oci8-1.4.10.tgz
./configure --with-oci8=shared,instantclient,/apps/oracleClient/oraInventory/product/11.1.0/client_1
cd oci8-1.4.10
./configure --with-oci8=shared,instantclient,/usr/lib/oracle/11.2/client64
rpm -ivh oracle-instantclient11.2-sqlplus-
echo '/usr/lib/oracle/11.2/client64/lib' > /etc/ld.so.conf.d/oracle-instantclient-x86_64.conf
yum install php-devel
wget http://pecl.php.net/get/oci8-2.0.2.tgz
pecl install oci8-2.0.2.tgz 
echo 'extension=oci8.so' > /etc/php.d/oci8.ini
/etc/init.d/httpd restart
