Creating a cs329 web server from scratch

First we want to configure AWS and rent the server using AWS EC2. Using the AWS browser console do the following.

  • Open the AWS EC2 Browser Console
  • Create security group (one time action)
    • cs329-webserver
    • HTTP, HTTPS from everywhere
    • SSH from BYU 128.187.0.0/16
    • Outbound to anywhere
    • Tag with Owner:cs329
  • Create EC2 instance
    • Select Ubuntu
    • Named cs329-webserver
    • Tag with Owner:cs329
    • t3.micro
    • Create key pair (one time action) cs329
    • Select security group: cs329-webserver
    • Enabled Credit specification:Unlimited in advanced details
  • Store key pair in development environment and restrict the rights
    • chmod 600 ~/keys/cs329/cs329.pem

Now we can install Caddy, NVM, Node, and PM2

  • Shell into server

    • ssh -i ~/keys/cs329/cs329.pem ubuntu@0.0.0.0 (substitute IP address)

  • Install mysql

    • sudo apt update
    • sudo apt upgrade
    • sudo apt install mysql-server
    • sudo mysql_secure_installation
    • sudo mysql 
      CREATE USER 'admin'@'localhost' IDENTIFIED WITH mysql_native_password BY 'superSecretPassword!123';
GRANT ALL ON *.* TO 'admin'@'localhost' WITH GRANT OPTION;
EXIT
    • mysql -u admin -p

  • Install Caddy

    sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

    • Test. curl localhost should display caddy HTML. You should also be able to hit if from your development environment in your browser using the instance's IP address

    • Allow the ubuntu user to modify the public_html static files and Caddyfile

      • sudo chown -R ubuntu /usr/share/caddy
      • sudo chown -R ubuntu /etc/caddy/Caddyfile

    • Create symlink for Caddyfile and Caddy static content directory

      • ln -s /etc/caddy/Caddyfile Caddyfile
      • ln -s /usr/share/caddy public_html

  • Replace default Caddy static files with file found in the webprogramming329 repo

    • scp -i ~/keys/cs329/cs329.pem webServerDefault.html ubuntu@0.0.0.0:public_html/index.html
    • Hitting the server from the browser should now display the course default page.

  • Install node.js

    • curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
    • . ~/.nvm/nvm.sh
    • nvm install --lts (this installed version 20.12.2)

  • Set up PM2

    • npm install pm2 -g

  • Add service directory

    • Create the services directories mkdir -p ~/services

  • Deploy JWT-pizza-factory

    cd jwt-pizza-factory
./deployService.sh -k ~/keys/cs329/cs329.pem -h cs329.click

  • Test that they work with node and curl

    • cd ~/services/jwt-pizza-factory
    • node index.js 4000
    • curl -v http://localhost:4000
    • Stop the server

  • Deploy JWT-pizza-service

    cd jwt-pizza-service
./deployService.sh -k ~/keys/cs329/cs329.pem -h cs329.click

  • Register pizza factory service with PM2

    • cd ~/services/jwt-pizza-factory && pm2 start index.js -n jwt-pizza-factory -- 4000

  • Register pizza service with PM2

    • cd ~/services/jwt-pizza-service && pm2 start index.js -n jwt-pizza-service -- 3000

  • Save the pm2 changes.

    • pm2 save
    • pm2 startup will show you the command daemonize PM2. Run that command.

  • Test that they work

    • curl http://localhost:3000

  • Configure Caddy to run services

    • edit Caddyfile sudo vi ~/Caddyfile
    • replace the contents of the Caddyfile with Caddyfile-base found in the devops329 repo.
    • save and restart Caddy sudo service caddy restart
