Or clone from GitHub:
git clone https://github.com/your-repo.git
Setting Up a Process Manager
Use PM2 to manage your app:
npm install pm2 -g
npm start
pm2 start server.js –name “myapp”
Make sure PM2 restarts your app on reboot:
pm2 startup
pm2 save
5. Configuring a Reverse Proxy with Nginx
Why You Need a Reverse Proxy
A reverse proxy is an intermediary between backend servers and clients (such as web browsers) that helps to improve performance, security, and scalability. Rather than users accessing a server directly, their requests are routed through the reverse proxy beforehand, which then directs them to the intended destination.
Key Advantages
- Enhanced Security – Your backend servers are concealed by a reverse proxy from direct attacks such as DDoS, SQL injection, and malware.
- Load Balancing – It spreads incoming traffic across multiple servers to avoid overload and provide high availability.
- SSL Termination – It handles SSL/TLS encryption, removing the processing load from backend servers for improved performance.
- Caching and Compression – By keeping copies of popular content and compressing data, it accelerates load times and conserves bandwidth.
- Access Control & Authentication – It can enforce security policies, requiring authentication before allowing access to backend services.
A reverse proxy is essential for modern web applications, enhancing security, efficiency, and reliability while making it easier to scale your infrastructure. Whether hosting a website, API, or cloud-based service, implementing a reverse proxy is a smart move.
Installing and Configuring Nginx
Create a new config file:
sudo nano /etc/nginx/sites-available/myapp
Adding the following:
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://localhost: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;
}
}
Enable the config and restart Nginx:
sudo ln -s /etc/nginx/sites-available/myapp /etc/nginx/sites-enabled/
sudo systemctl restart nginx
6. Securing Your Deployment
Setting Up a Firewall with UFW
Allow SSH, HTTP, and HTTPS traffic:
sudo ufw allow OpenSSH
sudo ufw allow ‘Nginx Full’
sudo ufw enable
Securing with SSL (Let’s Encrypt & Certbot)
Install Certbot:
sudo apt install certbot python3-certbot-nginx
Get an SSL certificate:
sudo certbot –nginx -d yourdomain.com
Set up auto-renewal:
sudo certbot renew –dry-run
Enforcing Security Best Practices
- Use .env for secrets.
- Enable automatic updates.
- Set correct file permissions.
7. Automating Deployment with CI/CD
Introduction to CI/CD Pipelines
A CI/CD pipeline (Continuous Integration/Continuous Deployment) is an automated process that assists developers in quickly and effectively building, testing, and releasing software. It automates tasks, minimizing errors and speeding up software delivery.
How Does It Work?
- Continuous Integration (CI): Developers integrate their code regularly into a common repository. Automated testing occurs to detect bugs early.
- Continuous Deployment (CD): Automatically deploys the code to production or staging after it has been tested. It allows for fast and consistent software updates.
Why Does It Matters?
- Speed: Eliminates time-consuming repetitive work, shortening deployment time.
- Quality: Pinpoints problems early with automated tests.
- Reliability: Provides reliable deployments with fewer human errors.
Platforms such as Jenkins, GitHub Actions, GitLab CI/CD, and AWS CodePipeline make it easier for teams to apply CI/CD, accelerating and streamlining software development. From startups to large enterprises, incorporating CI/CD can greatly enhance your software delivery pipeline.
Using GitHub Actions
Create a .github/workflows/deploy.yml file:
name: Deploy
on: push
jobs:
deploy:
runs-on: ubuntu-latest
steps:
– uses: actions/checkout@v2
– name: Deploy via SSH
run: ssh user@your-server-ip ‘cd /path/to/app && git pull && pm2 restart myapp’
8. Monitoring and Maintenance
Monitoring App Performance
Use PM2:
pm2 monit
pm2 logs
Setting Up Alerts
Use uptime monitoring tools like UptimeRobot or New Relic.
Scaling Considerations
- Vertical scaling: Upgrade server resources.
- Horizontal scaling: Load balance multiple instances.
