Step-by-Step Deployment Guide

1. Verify Installation # Run health check sudo ./scripts/health-check.sh # Check services systemctl status nginx mongodb pm2 # View report cat /var/log/elite-setup/report.html 2. Upload Your Code # Via Git (recommended) cd /var/www git clone https://github.com/user/app.git # Via SCP scp -r my-app/ user@server:/var/www/ 3. Install Dependencies cd /var/www/your-app npm install --production npm run build # If using frontend

4. Configure Environment # Create .env file cat > .env << EOF NODE_ENV=production PORT=3000 MONGODB_URI=mongodb://admin:pass@\ localhost:27017/myapp?authSource=admin EOF # Get MongoDB credentials cat /root/.mongodb_credentials 5. Start with PM2 # Start application pm2 start server.js --name my-app -i max # Save configuration pm2 save pm2 startup 6. Configure Nginx # Create site configuration sudo nano /etc/nginx/sites-available/app

Example Nginx Configuration

server {
server_name yourdomain.com www.yourdomain.com;

# Proxy to Node.js app
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_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_cache_bypass $http_upgrade;
}

listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}

server {
if ($host = www.yourdomain.com) {
return 301 https://$host$request_uri;
}
if ($host = yourdomain.com) {
return 301 https://$host$request_uri;
}
listen 80;
server_name yourdomain.com www.yourdomain.com;
return 404;
}

Enable and reload:

sudo ln -s /etc/nginx/sites-available/app /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

MongoDB Connection Setup

# Get credentials
cat /root/.mongodb_credentials

# Connect to MongoDB
mongosh "mongodb://admin:YOUR_PASSWORD@localhost:27017/?authSource=admin"

# Create application database
use myapp
db.createUser({
user: "myappuser",
pwd: "secure_password",
roles: [{ role: "readWrite", db: "myapp" }]
})

Update connection string in your app:

// In your Node.js app
const MONGODB_URI = "mongodb://myappuser:secure_password@localhost:27017/myapp?authSource=myapp";

Troubleshooting

Common Issues & Solutions

MongoDB Connection Failed

# Check MongoDB status
sudo systemctl status mongodb

# Check logs
sudo tail -f /var/log/mongodb/mongod.log

# Verify authentication
mongosh --username admin --password --authenticationDatabase admin

# Restart MongoDB
sudo systemctl restart mongodb

Common causes:

• Wrong credentials
• Authentication database mismatch
• Port 27017 blocked
• MongoDB not started

Nginx Configuration Error

# Test configuration
sudo nginx -t

# Check error logs
sudo tail -f /var/log/nginx/error.log

# Reload configuration
sudo systemctl reload nginx

Common causes:

• Syntax errors in config
• Certificate path issues
• Port already in use
• Incorrect server_name

PM2 Process Crashes

# View PM2 logs
pm2 logs

# Check process status
pm2 list

# Restart app
pm2 restart app-name

# Monitor in real-time
pm2 monit

Common causes:

• Uncaught exceptions
• Memory leaks
• Port conflicts
• Missing dependencies

Firewall Blocking Connections

# Check UFW status
sudo ufw status verbose

# Allow specific port
sudo ufw allow 3000/tcp

# Reload firewall
sudo ufw reload

Common causes:

• Port not allowed in UFW
• Wrong protocol (TCP/UDP)
• Application not listening
• SELinux restrictions

Security Hardening Applied

Network Security

UFW Firewall Configuration:

# Default policies
ufw default deny incoming
ufw default allow outgoing

# Allowed ports
ufw allow 22/tcp # SSH
ufw allow 80/tcp # HTTP
ufw allow 443/tcp # HTTPS
ufw allow 27017/tcp # MongoDB (localhost only)

# Rate limiting
ufw limit 22/tcp

Fail2ban Protection:

[sshd]
enabled = true
maxretry = 3
findtime = 600
bantime = 3600

Authentication & Access

SSH Hardening:

# /etc/ssh/sshd_config
PermitRootLogin no
PasswordAuthentication no
PubkeyAuthentication yes
X11Forwarding no
MaxAuthTries 3

MongoDB Authentication:

// Required authentication
security:
authorization: enabled

// Admin user
db.createUser({
user: "admin",
pwd: "[secure-random-password]",
roles: ["userAdminAnyDatabase", "readWriteAnyDatabase"]
})

Web Security Headers

Nginx Security Headers:

# Security headers
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-Content-Type-Options "nosniff" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header Referrer-Policy "no-referrer-when-downgrade" always;
add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;

# HSTS (only with SSL)
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

System Security

Automatic Updates:

# Unattended security updates
apt-get install -y unattended-upgrades
dpkg-reconfigure -plow unattended-upgrades

System Limits:

# /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 32768
* hard nproc 32768

Post-Installation Security Checklist

Task	Priority	Status
Change default MongoDB password	Critical	⬜
Setup SSH key authentication	Critical	⬜
Configure automatic backups	High	⬜
Enable monitoring & alerting	High	⬜

View complete security checklist

# Generated at: /var/log/elite-setup/security-checklist.txt
cat /var/log/elite-setup/security-checklist.txt

Recommended Actions:

1. Change default MongoDB admin password immediately
2. Setup SSH keys and disable password authentication
3. Configure automated backups (daily recommended)
4. Enable monitoring and alerting (Prometheus, Grafana, or similar)
5. Review firewall rules for your specific needs
6. Test disaster recovery procedures
