Install ioncube on Linux server

  1. Begin by downloading the latest loaders to your computer from http://www.ioncube.com/loaders.php
  2. Extract the contents of the archived file on your local PC to a folder of your choice.
  3. Upload the folder IONCUBE via FTP to your domain webspace
  4. Now establish an SSH connection with server using a suitable client (e.g. Putty for PC’s or Terminal on Mac). This is usually done using the command: SSH rootusername@yourserver.com (you will then be asked for your password).
  5. You will need to browse to the public folder where you uploaded the IONCUBE directory (search internet for change and view directory commands in Unix).
  6. Move the ioncube folder to a permanent location by entering: mv ioncube /usr/local
  7. Next, you need to locate the php.ini file, to do this enter: locate php.ini – You should find it is in /usr/local/lib/php.ini. Now that you know the location of php.ini you need to edit it. pico /usr/local/lib/php.ini
  8. Now find where other zend extentions are in the file: ctrl + w: zend_extension
  9. Paste in your new line for ioncube loader: zend_extension = /usr/local/ioncube/ioncube_loader_lin_x.so (Replace x with your version of PHP eg. 4.4)
  10. Save the changes: ctrl + X then Y and enter
  11. Restart the web server to take effect: /etc/init.d/httpd restart

That’s it! Ioncube should now be installed & working on your server. To verify the installation was successful, check the PHP Info output for your server and you should see a new section which reads:

PHP enable error reporting

You can set PHP error reporting on in php.ini file (in case you have access to this file). Set the following lines:

error_reporting = E_ALL
display_errors = On

If you have no access to php.ini file but you can modify .htaccess file on your server (in root of your public_hml folder – your Joomla! site), try to add the following code there (on some servers this option is disabled, so you need to ask your webhosting operator):

# Displaying PHP errors
php_flag display_errors on
php_value error_reporting 6143
