There will be a time when you need IonCube loader in order to run PHP scripts encoded with IonCube. So here's a quick guide which will tell you how to install IonCube loader using SHELL.

Root Shell Access to your server.
Download the loader suitable for your server from here: http://www.ioncube.com/loader_download.php.
Unpack the binary file by using this command tar -zxvf ioncube_loaders.tar.gz (Change the ioncube_loaders.tar.gz to the file name appropriate for your server)
After extracting it will create a folder called ioncube. Now use this command: cd ioncube
Copy ioncube-install-assistant.php to a web directory by typing this command cp ioncube-install-assistant.php /home/userdirectoryhere/www
Visit that file by going to http://www.yourdomain.com/ioncube-install-assistant.php.
And you should see something like below (depends on your server and configurations):

PHP Version 4.3.3
Operating System Linux
Threaded PHP No
php.ini file /usr/local/lib/php.ini
Required Loader ioncube_loader_lin_4.3.so

Go back to where you extracted the ioncube folder by using cd..
Now move the ioncube folder in a safe and permanent location by using command: mv ioncube /usr/local
Now edit the php.ini file for example: pico /usr/local/lib/php.ini
Look for [zend] by typing CTRL + W and typing [zend]
Paste the following line under [zend], zend_extension = /usr/local/ioncube/ioncube_loader_lin_4.3.so
Press CTRL + X, type Y and press Enter.
Restart the server by typing: /etc/init.d/httpd restart
Your installation is done.

*If you have Zend Optimizer installed then put the ioncube loader line before the Zend Optimizer line, else you will receive any error.

thanks this is old but very useful.

Thanks and I must agree with bokoNet

Great info :)

Alternatively, you could simply log in to cPanel through WHM(http://IPHERE:2086/" and then press "EasyApache" and then when you rebuild it, simply enable IonCube Loader.

Its really as simple as that!

Thanks, usefull.

wow thank you very much :)

This is pretty old and make sure you all are you using ioncube_loader_lin_5.3.so and not 4.3 .

This is pretty old and make sure you all are you using ioncube_loader_lin_5.3.so and not 4.3 .

ioncube_loader_lin_5.3.so for 64bit OS
ioncube_loader_lin_5.2.so for 32bit OS

;)

ioncube_loader_lin_5.3.so for 64bit OS
ioncube_loader_lin_5.2.so for 32bit OS

;)

Thats incorrect and the 5.3 will work with a 32bit OS. Why do you think they include it in the 32bit download?
