How to install or reinstall ioncube in centos-web panel

Updated: 28 September 2026 · Applies to: CentOS Web Panel

Reinstall the ionCube Loader on a CentOS Web Panel (CWP) server when PHP reports it missing or outdated.

Steps (root)

1. Update CWP: sh /scripts/update_cwp.
2. Replace the loader files:

   cd /usr/local
   mv ioncube ioncube-bak
   wget https://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
   tar -zxvf ioncube_loaders_lin_x86-64.tar.gz

3. Enable the loader for your PHP version in CWP's PHP settings (or check the zend_extension line), and restart PHP-FPM.

Check with php -v.
