Note : In this articles we are using ioncube_loader_lin_5.3.so as PHP version installed on the server was PHP 5.3
Now edit php.ini file. To find location of php.ini, run
#php -i| grep php.ini
In my case, php.ini was in /etc/php.ini folder
Append the following line to end on php.ini
#vi /etc/php.ini
zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.3.so
Finally restart the apache server
#service httpd restart
That’s it.
