If you don't have mysql type:
$ sudo apt-get install mysql-server
sudo service mysql restart
$ sudo apt-get install nodejs
$ sudo apt-get install npm
$ npm install mysql (if no-response $ npm config set strict-ssl false)
$ npm install express
$ npm install body-parser
$ sudo service mysql restart
Oper init1 and init2 and modify the variable "password" at the top of code
$ nodejs init1.js
$ nodejs init2.js
$ nodejs index.js
Enjoy
