Enable port 3306 on the server security group

Package the local egg and package the transport

  1. CD to the project
  2. npm install –production
  3. tar -zcvf .. /release.tgz .

So it’s packaged and it’s sent up to your server via file transfer and in this case I’m using FashFXP and then it’s transferred up there

Tar -zxvf release.tgz

$ npm i egg-scripts –save

Add NPM scripts to package.json:

{
  "scripts": {
    "start": "egg-scripts start --daemon"."stop": "egg-scripts stop"}}Copy the code

This allows us to start or stop the application with the NPM start and NPM stop commands.
