Setup EC2 for Node.js Apps

In this tutorial, we will set up an EC2 instance for node.js.

Prerequisites​

Launch an EC2 instance​

You can launch an EC2 instance using the AWS CLI. To launch an EC2 instance, run the following command:

aws ec2 run-instances --image-id ami-0b9e5e9e --count 1 --instance-type t2.micro --key-name my-key-pair --security-group-ids sg-0b9e5e9e --subnet-id subnet-0b9e5e9e

Steps​

  1. Launch EC2 instance
  2. SSH to instance
  3. Install Node.js with NVM
  4. Setup node app on server
  • rsync -av ~/Development/temp/app1 lightsail1:~/app1
  1. Install Nginx with apt-get
    • $ sudo apt-get install nginx
    • $ sudo /etc/init.d/nginx start
  2. Route nginx ports

  • sudo nano /etc/nginx/sites-available/default

    server {
      listen 80;

      server_name example.com;

      location / {
          proxy_pass http://127.0.0.1:3000;
          proxy_http_version 1.1;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection 'upgrade';
          proxy_set_header Host $host;
          proxy_cache_bypass $http_upgrade;
      }
    }

  • sudo service nginx restart

  1. Setup Node to use pm2 (or forever)

  • sudo npm install pm2 -g

  • pm2 start app.js

  • pm2 startup ubuntu

    #copy all of the files in this directory to the /home/will/newapp directory
    rsync -av ~/Development/temp/app1 lightsail1:~/app1

sudo apt-get install libcap2-bin sudo setcap cap_net_bind_service=+ep /usr/bin/node

SSH Tips​

  • ssh user@ip-or-dns-name
  • apt-get is a package manager for Linux (Ubuantu)
  • exit
  • rsync -av . user@ip-or-dns-name:~/newdir

Passwordless SSH​

On local Mac

  1. copy .pem to ~/.ssh/ mv ~/Development/_resources/aws-cli-bash/ec2/dabblelab-dev.pem ~/.ssh/dabblelab-dev.pem
  2. chmod 600 ~/.ssh/dabblelab-dev.pem | chmod 400 ~/.ssh/dabblelab-dev.pem
  3. chmod 700 ~/.ssh/
  4. touch ~/.ssh/config
  5. chmod ~/.ssh/config 644
  6. nano ~/.ssh/config host dev1 Hostname [the IP or dns name] User root IdentityFile ~/.ssh/[your keypair here]
  7. ssh dev1
