Your web server should meet the following criteria before installing the frontend VCL Frontend Codecode:
- Apache HTTP Server v1.3 or v2.x with SSL enabled - while VCL may run under another webserver capable of running PHP code, it has only been tested to work with Apache HTTP Server
- PHP 5
- php modules that should be installed (depending on your Linux distro, some of these may be compiled in to php instead of being a separate module):
- php-gd
- php-json (if your PHP version is < 5.2, this is not required)
- php-mcrypt
- php-mysql
- php-openssl
- php-sysvsem
- php-xml
- php-xmlrpc
- useful to have the server set up to be able to send debugging emails
- php-mcrypt requires libmcrypt and mcrypt libraries as dependencies. These may need to be installed first.
