How To Install IonCube Loader on CentOS 8

Install IonCube Loader on CentOS 8

In this tutorial, we will show you how to install IonCube Loader on CentOS 8. For those of you who didn’t know, IonCube Loader 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 through the step-by-step installation IonCube Loader on a CentOS 8 server.


  • A server running one of the following operating systems: CentOS 8.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • 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 8

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

sudo dnf update

Step 2. Install LAMP server.

A CentOS 8 LAMP server is required. If you do not have LAMP installed, you can follow our guide here.

Step 3. Installing IonCube Loader on CentOS 8.

Now, we download the latest version of ionCube Loader from its official website:

wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
tar xzf ioncube_loaders_lin_x86-64.tar.gz

Once the download is completed,  we check on where they have loaded extensions to PHP:

php -i | grep extension_dir

The result should look like this:

extension_dir => /usr/lib64/php/modules => /usr/lib64/php/modules

Now, copy the ionCube loader module from the IonCube directory that matches your PHP version to the PHP extension directory:

cp ioncube/ioncube_loader_lin_7.2.so /usr/lib64/php/modules/

Once the file has been copied to the extensions directory, we need to make sure that the PHP configuration file is updated to use the correct extension:

nano /etc/php.ini

At the very top of the file let’s add the following line:

zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_7.2.so

Now, we can restart the Apache webserver so that the changes take place:

systemctl restart httpd

Now, after checking our PHP version should already be visible our IonCube:

$ php -v
