How To Install ionCube PHP Loader on Rocky Linux 9?

To complete this guide, you must access to your server as a root user. For this purpose, you can visit our guide on Initial Server Setup with Rocky Linux 9.

Now follow the steps below to complete this guide:

Step 1 – Install PHP 8.1 on Rocky Linux 9

Rocky Linux 9 ships with the default PHP 8.0, but for installing the ionCube loader you must have PHP 8.1 installed on your server. To do this, follow the steps below:

First, you must run the system update:

sudo dnf update -y

Then, install the Epel repository on your server with the following command:

sudo dnf install epel-release -y

Now use the command below to add the Remi repository:

sudo dnf install dnf-utils https://rpms.remirepo.net/enterprise/remi-release-9.rpm

Again run the system update:

sudo dnf update -y

Here you need to remove the PHP and PHP-FPM previous versions if you have them installed on your server. To do this, run the following command:

sudo dnf remove php php-fpm -y

Then remove the rest of the package extensions with the command below:

sudo dnf remove php* -y

To reset the PHP module list on Rocky Linux 9, you can use the following command:

sudo dnf module list reset php -y
Output
Remi's Modular repository for Enterprise Linux 9 - x86_64
Name      Stream       Profiles                       Summary
php       remi-7.4     common [d], devel, minimal     PHP scripting language
php       remi-8.0     common [d], devel, minimal     PHP scripting language
php       remi-8.1     common [d], devel, minimal     PHP scripting language
php       remi-8.2     common [d], devel, minimal     PHP scripting language

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

Now you need to enable PHP 8.1 on Rocky Linux 9 with the command below:

sudo dnf module enable php:remi-8.1

At this point, you have added the Remi PHP repository and enabled PHP 8.1 to be the default version on your system, you can install PHP 8.1 and httpd service with the following command:

sudo dnf install php httpd -y

Verify your PHP installation by checking its version:

php --version

How To Activate ionCube Loader in PHP?

At this point, you need to find the location of the extension directory. To do this, you can use the following command:

php -i | grep extension_dir

Next, copy the ionCube loader module from the ionCube directory that matches your PHP version to the PHP extension directory on Rocky Linux 9:

cp ioncube/ioncube_loader_lin_8.1.so /usr/lib64/php/modules/

Then, you need to enable the ionCube loader by editing the php.ini file. You can use your favorite text editor, here we use the vi editor:

vi /etc/php.ini

Add the following line at the end of the file:

zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_8.1.so

When you are done, save and close the file.

Finally, restart Apache to apply the changes:

systemctl restart httpd
