​
SSL/TLS Certificate Setup

​
Let’s Encrypt with Certbot

# Install certbot
sudo apt-get update
sudo apt-get install certbot python3-certbot-nginx

# Obtain certificate
sudo certbot --nginx -d deepwikiopen.com -d www.deepwikiopen.com

# Auto-renewal setup
sudo crontab -e
# Add: 0 12 * * * /usr/bin/certbot renew --quiet

​
Custom Certificate Setup

# Generate private key
openssl genrsa -out deepwikiopen.key 2048

# Generate certificate signing request
openssl req -new -key deepwikiopen.key -out deepwikiopen.csr

# After receiving certificate from CA
sudo mkdir -p /etc/ssl/certs /etc/ssl/private
sudo cp deepwikiopen.crt /etc/ssl/certs/
sudo cp deepwikiopen.key /etc/ssl/private/
sudo chmod 644 /etc/ssl/certs/deepwikiopen.crt
sudo chmod 600 /etc/ssl/private/deepwikiopen.key

​
SSL Configuration Best Practices

# Strong SSL configuration
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384;
ssl_prefer_server_ciphers off;
ssl_session_cache shared:SSL:10m;
ssl_session_tickets off;
ssl_stapling on;
ssl_stapling_verify on;

# HSTS

Performance Tuning

​
Application Performance Optimization

// performance.js
const compression = require('compression');
const responseTime = require('response-time');
const cluster = require('cluster');
const numCPUs = require('os').cpus().length;

// Cluster setup for production
if (cluster.isMaster && process.env.NODE_ENV === 'production') {
  console.log(`Master ${process.pid} is running`);
  
  // Fork workers
  for (let i = 0; i < numCPUs; i++) {
    cluster.fork();
  }
  
  cluster.on('exit', (worker, code, signal) => {
    console.log(`Worker ${worker.process.pid} died`);
    cluster.fork();
  });
} else {
  const express = require('express');
  const app = express();
  
  // Performance middleware
  app.use(compression({
    filter: (req, res) => {
      if (req.headers['x-no-compression']) {
        return false;
      }
      return compression.filter(req, res);
    },
    level: 6,
    threshold: 1024
  }));
  
  app.use(responseTime((req, res, time) => {
    console.log(`${req.method} ${req.url} - ${time}ms`);
  }));
  
  // Connection pooling
  const { Pool } = require('pg');
  const pool = new Pool({
    connectionString: process.env.DATABASE_URL,
    max: 20,
    idleTimeoutMillis: 30000,
    connectionTimeoutMillis: 2000,
  });
  
  // Cache configuration
  const NodeCache = require('node-cache');
  const cache = new NodeCache({
    stdTTL: 600, // 10 minutes
    checkperiod: 120,
    useClones: false
  });
  
  // Caching middleware
  const cacheMiddleware = (duration) => {
    return (req, res, next) => {
      const key = req.originalUrl || req.url;
      const cached = cache.get(key);
      
      if (cached) {
        return res.json(cached);
      }
      
      res.sendResponse = res.json;
      res.json = (body) => {
        cache.set(key, body, duration);
        res.sendResponse(body);

    };
  };
  
  app.use('/api/search', cacheMiddleware(300)); // 5 minutes cache
  
  console.log(`Worker ${process.pid} started`);

Database Query Optimization

-- Create appropriate indexes
CREATE INDEX CONCURRENTLY idx_articles_title_search ON articles USING gin(to_tsvector('english', title));
CREATE INDEX CONCURRENTLY idx_articles_content_search ON articles USING gin(to_tsvector('english', content));
CREATE INDEX CONCURRENTLY idx_articles_created_at ON articles(created_at DESC);
CREATE INDEX CONCURRENTLY idx_articles_category ON articles(category_id);

-- Partitioning for large tables
CREATE TABLE articles_2023 PARTITION OF articles
    FOR VALUES FROM ('2023-01-01') TO ('2024-01-01');

-- Query optimization examples
EXPLAIN ANALYZE SELECT * FROM articles 
WHERE to_tsvector('english', title || ' ' || content) @@ to_tsquery('search_term')
ORDER BY created_at DESC 
LIMIT 20;

-- Connection pooling settings
ALTER SYSTEM SET max_connections = 200;
ALTER SYSTEM SET shared_buffers = '2GB';
ALTER SYSTEM SET effective_cache_size = '6GB';
SELECT pg_reload_conf();
