Raspberry Pi Server Code for SBHS

This repository contains the code to be used in the Raspberry Pis for the load sharing SBHS architecture.

Setup Instructions

• Install an operating system on the Raspberry Pi (preferably Raspbian). Click here for further instructions on how to install Raspbian.
• Install Apache

sudo apt-get install apache2

Check your installation by typing sudo service apache2 status

• Install MySQL.

sudo apt-get install mysql-server

• Download the setup script in your working directory from here. You can type the following command as well to download the script.

wget https://gist.githubusercontent.com/coderick14/26e85f1bf2104fc461e4c60e97bff2cf/raw/977e844f4e854461c83627388000599a9b48d34b/setup_pi.sh

• Run the setup script. The Raspberry Pi must be connected to the internet for this script to execute. Make sure you have required access to this Git repository to download the source code.

bash setup_pi.sh

• You will prompted for five fields during the execution of the script.
  • database host : Enter the IP of the master server here
  • database user : Enter the username who has remote access to the database. (Type sbhs_pi if you have followed this README for the master server)
  • database password : Password for the database user
  • database name : The database name (Usually sbhs)
  • database port : Type 3306 here. Unless you have explicitly specified a different port for MySQL.

NOTE :

Raspberry Pis DO NOT have an RTC (Real Time Clock). Thus, synchronizing time and date with that of the master server is an issue. Make sure that you run the script synctime.sh from the master server whenever a Pi reboots or a new Pi is connected. This script wil sync the time of all the Raspberry Pis with that of the master server.
