Deploy a Node.js / Next.js app on a cloud server

Steps

1. 1Install Node.js 22 LTS

   Install the current LTS from the NodeSource repository.

   Copy

   curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
   sudo apt install -y nodejs git
   node -v

2. 2Fetch and build the app

   Clone your repository, install dependencies and build for production.

   Copy

   git clone https://github.com/KULLANICI/PROJE.git ~/web
   cd ~/web
   npm ci
   npm run build

3. 3Run with PM2

   The app restarts if it crashes and starts on boot. Run the line printed by pm2 startup.

   Copy

   sudo npm install -g pm2
   pm2 start npm --name web -- start
   pm2 startup systemd
   pm2 save

4. 4Nginx reverse proxy

   Nginx forwards requests from port 80 to the app on port 3000.

   Copy

   sudo apt install -y nginx
   sudo tee /etc/nginx/sites-available/web >/dev/null <<'EOF'
   server {
       listen 80;
       server_name example.com www.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_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
       }
   }
   EOF
   sudo ln -s /etc/nginx/sites-available/web /etc/nginx/sites-enabled/
   sudo nginx -t && sudo systemctl reload nginx

5. 5Free SSL

   Certbot obtains the certificate, configures Nginx for HTTPS and renews automatically.

   Copy

   sudo apt install -y certbot python3-certbot-nginx
   sudo certbot --nginx -d example.com -d www.example.com
