[b]How to install the Red Matrix on a Raspberry Pi[/b] [zrl=[baseurl]/help/main] Back to the main page[/zrl] Last update 2014-02-22 [hr] You just bought a Raspberry Pi and want to run the RED Matrix with your own domain name? Then this page is for you! You will: [list=1] [*] Install Raspberry OS (Debian Linux) on a Raspberry [*] Install Apache Web Server, PHP, MaySQL, phpMyAdmin [*] Register a free domain (dynamic DNS) and use it for your RED hub [*] Install the RED Matrix [*] Keep your Raspberry Pi and your Redmatrix up-to-date [*] TODO Running Friendica with SSL [*] TODO Make the webserver less vulnarable to attacks [/list] [size=large]1.
