How to Install IonCube Loader in CentOS 6 / CentOS 7

IonCube Loader is a crucial PHP module that decodes encrypted PHP files and is often required for many PHP-based applications. It serves a dual purpose: protecting PHP applications from unauthorized execution and accelerating website performance.

This guide will walk you through the process of installing the IonCube Loader on CentOS 6 and CentOS 7. Although this tutorial is focused on CentOS, the steps are also applicable to other Linux distributions.

Before we dive into the installation process, it’s important to note that your PHP version must match the IonCube version. For instance, PHP 5.5 will use the file: ioncube_loader_lin_5.5.so, PHP 5.4 will use the file: ioncube_loader_lin_5.4.so, and so on.

Step 1: Verify Your PHP and IonCube Version

First, you need to check and verify your PHP and IonCube version. To do this, you can use the following command:

# php -v

This command will display your current PHP version. Make sure that your PHP version matches the IonCube version you intend to install.

Step 2: Create a Directory for IonCube

Next, create a directory for IonCube using the following command:

# mkdir /usr/local/ioncube

This command will create a new directory at /usr/local/ioncube where you will store the IonCube files.

Step 3: Download and Extract IonCube

Now, you need to download and extract the IonCube files. Use the following commands to do this:

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

These commands will download the IonCube files from the official website and then extract them.

Open the extracted IonCube folder and copy the IonCube loader file that matches your PHP version. Use the following commands:

# cd ioncube
# cp -p ioncube_loader_lin_5.4.so /usr/local/ioncube

Replace “5.4” with your PHP version.

Step 5: Locate the php.ini File

You need to locate the php.ini file. This is how you can find the location of php.ini:

#php -i| grep php.ini

This command will display the path to your php.ini file.

Step 6: Edit the php.ini File

Now, you need to edit the php.ini file and add the path to the IonCube loader. Use the following command to open the php.ini file:

# vim /etc/php.ini

Add the following line at the bottom of the php.ini file:

zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.4.so

Replace “5.4” with your PHP version.

Step 7: Verify the Installation

Finally, verify that the IonCube loader has been installed correctly. Use the following command:

# php -v

If the output includes “with the ionCube PHP Loader”, it means you have successfully installed and configured the IonCube PHP loader in your Linux system.
