Secure Moodle on Raspberry Pi Model 2, Gentoo Linux and Nginx server: Difference between revisions

Revision as of 07:54, 22 July 2017

Hi,

I want to share my experiences when I installed Moodle on a Raspberry Pi Model 2 hardware, on which is running Gentoo Linux operating system and the Nginx web server. It can reach here: [1]

First I installed Gentoo Linux on my Raspberry Pi Model 2 hardware by following this guide: [2]

Then I installed and did setup Nginx web server by following these guids: [3] [4]

My nginx.config file is: user nginx nginx; worker_processes 1;
