Apache Powers MyWebUniversity

Apache with CGI scripts IS how MyWebUniversity.com serves all chapter content — mod_cgid, VirtualHost, and SSL are directly applicable to this project.

🟢

NGINX at Scale

NGINX handles 100,000+ simultaneous connections with minimal RAM. Its event-driven model makes it ideal for high-traffic reverse proxying.

🔒

Free TLS with Let's Encrypt

Certbot auto-configures Apache and NGINX with free, auto-renewing Let's Encrypt certificates — HTTPS for every site at no cost.

🔀

Reverse Proxy Standard

Every modern web stack uses Apache or NGINX as a reverse proxy in front of Node.js, Python, Java, or Go backends. Essential architecture skill.

Run Apache:

# Apache (Ubuntu/Debian)
sudo apt install apache2
sudo systemctl start apache2
sudo a2enmod rewrite ssl cgid headers
sudo a2ensite mysite.conf
sudo apache2ctl -t       # test config
sudo systemctl reload apache2

# NGINX (Ubuntu/Debian)
sudo apt install nginx
sudo systemctl start nginx
sudo nginx -t            # test config
sudo systemctl reload nginx

# Let's Encrypt (both)
sudo apt install certbot python3-certbot-apache python3-certbot-nginx
sudo certbot --apache -d example.com   # Apache TLS
sudo certbot --nginx  -d example.com   # NGINX TLS
sudo certbot renew --dry-run
