How To Install IonCube Loader on CentOS

Install IonCube Loader on CentOS

In this tutorial, we will show you how to install IonCube Loader on the CentOS system. For those of you who didn’t know, IonCube Loaders is basically an encryption/decryption utility for PHP applications that also assists in speeding up the pages that are served. It is often required for a lot of PHP-based applications.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation IonCube Loader on a CentOS system.


  • A server running one of the following operating systems: CentOS Linux.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install IonCube Loader on CentOS

Step 1. First, make sure that all your system packages are up-to-date by running the following dnf or yum commands in the terminal.

sudo dnf update

Step 2. Installing IonCube Loader on the CentOS system.

  • Method 1:

For CentOS 32-bit use:

wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.gz
tar xvfz ioncube_loaders_lin_x86.tar.gz

For CentOS x86_64 (64-bit):

cd ioncube
mkdir /usr/local/ioncube
cp ioncube_loader_lin_5.3.so /usr/local/ioncube

Copy ioncube_loader_lin_5.3.so as the PHP version installed on the server was PHP 5.3

Now edit php.ini file. To find the location of php.ini, run

php -i| grep php.ini
nano /etc/php.ini

Add the following line to end on php.ini

zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.3.so

Restart apache after IonCube Loaders installation

service httpd restart
php -v
  • Method 2:

Install IonCube Loaders via the atomic yum repository:

wget -q -O - http://www.atomicorp.com/installers/atomic |sh
yum install php-ioncube-loader -y

IonCube Loader should now be installed. You can check by creating a file called info.php in /var/www/html/ with the following content:

 <? phpinfo(); ?>
