Step 2: Go to your site’s public folder (root directory of your site) or DocumentRoot of your server.

# cd /path/to/site


# cd /usr/local/apache2/techoism
# cd /var/www/html

Step 3: Download IonCube Loader according to your system requirement.

For CentOS 32-bit use:
# wget

For CentOS 64-bit:
# wget

Step 4: After downloading IonCube, now extract the file using following command.

For CentOS 32-bit use:
# tar xvfz ioncube_loaders_lin_x86.tar.gz

For CentOS 64-bit use:
# tar xvfz ioncube_loaders_lin_x86-64.tar.gz

Step 5: Now use web browser browser (like Firefox, Chrome, etc) to access IonCube file loader-wizard.php via your server’s ip or domain name:

# http://192.168.X.X/ioncube/loader-wizard.php


Step 6: Now copy the loader .so file into modules directory:

32-bit server:

64-bit server:

# cp /usr/local/apache2/techoism/ioncube/ /usr/lib64/php/modules
# cp /var/www/html/ioncube/ /usr/lib64/php/modules
Step 7: – Now download the 20ioncube.ini file from the wizard. Once 20ioncube.ini file has been downloaded, upload that file to /etc/php.d directory. But simply I will prefer to open that file using Notepad then copy it to server by creating an file.
# vim /etc/php.d/20ioncube.ini

Now open the downloaded file using Notepad, then copy the content and paste it to new created file.

For 32-bit:
zend_extension = /usr/lib/php/modules/

For 64-bit:
zend_extension = /usr/lib64/php/modules/

Step 8: Restart Apache service:

# service httpd restart

Step 9: Go back to your browser where you open loader-wizard.php page. Scroll down to the bottom and click the link in “When the server software has restarted, click here to test the Loader.” line to re-test the configuration.

If you did everything correctly, you’ll see this message:

Loader Installed Successfully


The ionCube Loader version 4.4.1 for PHP 5.3 is installed and encoded files should run successfully.
