Minimum System Requirements

To be able to run the system your host / development environment has to meet the following requirements:

  • PHP 7.1 or higher ( 7.4 recommended ) 
  • PDO PHP Extension
  • cURL PHP Extension
  • OpenSSL PHP Extension
  • Mbstring PHP Extension
  • Tokenizer PHP Extension
  • Mcrypt PHP Extension
  • GD PHP Library
  • MySql 5.6
  • Redis or Memcached

The site is now running on a Raspberry PI Cluster with 4 Raspberry PI 4's all powered by POE hats, this reduces the power footprint even further as there is now only one power supply, the router does all of the hard work and supplies power to the cluster.

The Master runs Ubuntu 20.04 Server with SSD boot and the three workers all run using SD cards, we are planning in the near future to network boot these from the master node. Its a question of reliability and performance which I am researching at the moment. It may well turn out that the Master runs the NginX web server and the nodes supply the DB Server and redis, but agian we are checking perfomance with this configuration.
