Set up AWS server

Setting Up the server through AWS Once logged into the Amazon Web Services (AWS) console with the appropriate credentials, navigate to "Services" and select Elastic Compute Cloud (EC2). Select an appropriate Amazon Machine Image (AMI) (for this I selected Ubuntu Server).

Create an AWS instance. The steps "Configure Instance Details", "Add Storage", and "Add Tags" can be left at the default settings.

For the step "Configure Security Group" you can create a new security group giving it a relevant name. In order to serve an app, click "Add Rule" select type "HTTP" and add "80" as the Port Range.

Click "Launch" create a new key pair, and download the key pair. Save the .pem file for the key in the computer's .ssh file. Select "Launch Instance and then View Instances."

Connecting to the Instance through the Terminal Once the instance is running, open up the terminal, and set permissions for the key by running $ chmod 400 ~/.ssh/key-name.pem

Connect to the instance in your terminal by running: ssh -i ~/.ssh/whatever-your-key-name-is.pem [email protected]

Install Node Version Manager (NVM) by running: $ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash

Run the ~bachrc file b running

$ source ~/.bashrc

Install node by running $ nvm install latest version

Setting up HTTP endpoint Create a directory to contain the server and cd into, by running: $ mkdir server $ cd server

then start npm by running: npm init

Install express by running: $ npm install express --save-dev

Create an index.js file in the server. I used nano to edit the file by running: $ nano index.js

I gave it a very basic server code, which could be made more complex if needed.

const express = require('express') const app = express()

app.get('/', (req, res) => { res.send('Hello, world!') }) app.listen(3000, () => console.log('Server running on port 3000'))

We can start the server by running: Node index.js

To run the app on Port 3000, go back to the EC2 console, go to "Security Groups" right click the security group for this instance, click "edit inbound rules" and click "add rule". Select a "Custom TCP rule" and set the port range to 3000.

Select crl+x in the terminal to pause the server and to run the server in the background run: $ bg %1 To logout run: $exit

Setup Nginx and Connect to Port 80 Install nginx by running: sudo apt-get install nginx

Remove the default config file by running: sudo rm /etc/nginx/sites-enabled/default

Create a new config file sudo nano /etc/nginx/sites-available/express-server

server { listen 80; server_name express-server; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_pass http://127.0.0.1:3000; } }

Link the config file in sites enabled by running: $ sudo ln -s /etc/nginx/sites-available/tutorial /etc/nginx/sites-enabled/tutorial

Restart nginx by running: $ sudo service nginx restart

Start the app by running: node tutorial/index.js Pause server by running: ctrl+z &

resume the app as a background task by running: bg %1

Stop running the node process by running:

killall -9 node

Install PM2 by running:

$npm i -g pm2

Ensure the PMz restarts with the server by running: $pm2 startup

Start server by running: pm2 start server/index.js

Save the code by running: pm2 save

Deploying Content Create a GitHub repository Create and index.js file in the repo with same script as the index.js made previously

Ignore node_moduels and commit the repo.

SSH into the server and generate a key pair, and save it in GitHub.

Clone the github by running Git clone: git url

In the local version of the project, install npm globally:

The create a config file named: ecosystem.config.js module.exports = { apps: [{ name: 'aws-server', script: './index.js' }], deploy: { production: { user: 'ubuntu', host: 'ec2-18-188-229-1.us-east-2.compute.amazonaws.com', key: '~/.ssh/express.pem', ref: 'origin/master', repo: 'https://github.com/reperez120/aws-server.git', path: '/home/ubuntu/aws-server', 'post-deploy': 'npm install && pm2 startOrRestart ecosystem.config.js' } } }

Setup the directories on the remote by running: pm2 deploy ecosystem.config.js production setup

Commit the changes

Run the deploy command: pm2 deploy ecosystem.config.js production

Add the below deploy and restart script to package.json: "restart": "pm2 startOrRestart ecosystem.config.js", "deploy": "pm2 deploy ecosystem.config.js production",

Install PM2 locally and save, using --save-dev: npm i pm2 --save-dev

Commit changes and deploy running: npm run-script deploy Make sure the app restarts with server running: pm2 save

To serve an HTML file, add a public directory In the public file, create an index.html file with the content you wish to run Deploy the changes again running: npm run-script deploy
