You need to setup Raspberry Pi (minimal raspbian image) with something like this

sudo apt-get install python-pip libglib2.0-dev git apache2

sudo apt-get install mysql-server

sudo mysql_secure_installation

sudo apt-get install php libapache2-mod-php php-mcrypt php-mysql php-cli

sudo apt-get install phpmyadmin php-mbstring php-gettext

sudo apt-get install libmariadbclient-dev

sudo pip install MySQL-python

sudo systemctl restart apache2

For the mySQL database:

CREATE DATABASE ina_data;

CREATE TABLE ina_data.ina_values ( id INT NOT NULL AUTO_INCREMENT , bus_voltage FLOAT NOT NULL , load_voltage FLOAT NOT NULL , current FLOAT NOT NULL , millisec INT NOT NULL , timestamp DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP , PRIMARY KEY (id)) ENGINE = InnoDB;
