HOW TO INSTALL IONCUBE LOADER ON CENTOS 6.3

Download and uncompress the latest IonCube version:
# wget http://downloads2.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
# tar xvfz ioncube_loaders_lin_x86-64.tar.gz

Then we go to the new IonCube source directory:
# cd ioncube/

Move ioncube_loader_lin_5.3.so:
# mv ioncube_loader_lin_5.3.so /usr/lib64/php/modules

Now edit /etc/php.ini and add the line zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_5.3.so
right at the beginning:
# vi /etc/php.ini
[PHP] zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_5.3.so

Now restart Apache:
# /etc/init.d/httpd restart

You can test  by creating a small PHP file
# vi /var/www/html/info.php

<?php
phpinfo();
?>

Now we call that file in a browser (e.g. http://***your website*** /info.php)
If its not showing you might have to disable SElinux;
# vi /etc/selinux/config

All Done!
