Configuration files for EC2 to use node.js (e.g. NODE_ENV = production)

On the elastic bean stem, you can set the environment

option_settings:
  - namespace: aws:elasticbeanstalk:container:nodejs:staticfiles
    option_name: /public
    value: /public
  - option_name: NODE_ENV
    value: production

      

        
        
        
      

    

and also access variables in node / express for example

console.log('Using production settings.');
app.set('connection', mysql.createConnection({
  host: process.env.RDS_HOSTNAME,
  user: process.env.RDS_USERNAME,
  password: process.env.RDS_PASSWORD,
  port: process.env.RDS_PORT}));

      

        
        
        
      

    

Now if I have to do the same on EC2 (without using Elastic Beanstalk)

• How / where to set these environment variables
• How can I access them
