Use Node.js and Express.js with Nginx on a VM using GitHub to deployment

1. Prepare VM

• Update and install necessary packages:

  • sudo apt update && sudo apt upgrade -y
    sudo apt install git nodejs npm nginx -y

• Verify Node.js and npm installation:

  • node -v
    npm -v

• Install a process manager like PM2:

  • sudo npm install -g pm2

2. Clone and Set Up Project

• Navigate to the desired directory:

  • cd /var/www

• Clone your project repository:

  • git clone https://github.com/RosCheath/rupp-e-card.git
    cd rupp-e-card

• Install dependencies:

  • npm install

• Run the app with PM2:

  • cd src
    pm2 start app.js --name rupp-e-card
    pm2 save
    pm2 startup

3. Configure Nginx as a Reverse Proxy

• Create an Nginx configuration file for domain:

  • sudo nano /etc/nginx/sites-available/verify.rupp.edu.kh

• Add the following content:

  • server {
        server_name verify.rupp.edu.kh;
    
        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;
        }
    
        listen 80;
    }

• Enable the configuration:

  • sudo ln -s /etc/nginx/sites-available/verify.rupp.edu.kh /etc/nginx/sites-enabled/

• Test Nginx configuration:

  • sudo nginx -t

• Reload Nginx:

  • sudo systemctl reload nginx
