System Requirements

F3 needs at least the following server configuration:

APACHE Webserver

• PHP 5.4 or higher
• PCRE 8.02 or higher (usually shipped with PHP package, but needs to be additionally updated on CentOS or Red Hat systems)
• mod_rewrite and mod_headers enabled
• GD libary (for Image plugin)
• cURL, sockets or stream extension (for Web plugin)

Nginx and Lighttpd configurations are also possible.

If you have a custom server and want to have installed everything you could probably need, here is a debian 1-liner for you (cache module not included):
