πŸ“– About This Skill

name: Server description: Configure, deploy, and troubleshoot web servers, application servers, and containerized services.

Scope

This skill covers the software layer β€” what runs inside a machine. For infrastructure (provisioning VMs, SSH hardening, firewalls, backups), use the vps skill.

When to Use

  • Configuring nginx, Caddy, or Apache
  • Deploying Node.js, Python, Go, or other apps
  • Docker and Docker Compose setups
  • SSL/TLS certificates with Let's Encrypt
  • Reverse proxy and load balancing
  • Process management (pm2, systemd services)
  • Troubleshooting port conflicts, CORS, connection errors
  • Self-hosting (Plex, Nextcloud, game servers)
  • Local development servers (Vite, webpack-dev-server)

    • Common Pitfalls

  • Port already in use β€” Check with lsof -i :PORT or ss -tlnp | grep PORT, kill stale processes
  • CORS in development β€” Proxy through your dev server or configure backend headers, don't disable in production
  • SSL certificate issues β€” Certbot needs port 80/443 open, use --standalone or --webroot mode appropriately
  • nginx config not loading β€” Always run nginx -t before systemctl reload nginx
  • Docker container can't reach host β€” Use host.docker.internal (Docker Desktop) or 172.17.0.1 (Linux)
  • Process dies after SSH disconnect β€” Use systemd, pm2, or run inside tmux/screen
  • Wrong permissions on mounted volumes β€” Match container user UID with host file ownership

    • Patterns by Use Case

    | Use Case | Recommended Stack | |----------|-------------------| | Static site | Caddy (auto-SSL, zero config) | | Node.js app | PM2 + nginx reverse proxy | | Python (Django/FastAPI) | Gunicorn + nginx | | Multiple services | Docker Compose + Traefik | | Game server | Dedicated container + port mapping |

    For framework-specific configs, see configs.md. For Docker Compose patterns, see docker.md.

    Debugging Checklist

    1. Is the process running? systemctl status or docker ps 2. Is it listening? ss -tlnp | grep PORT 3. Can you reach it locally? curl localhost:PORT 4. Firewall blocking? Check ufw status or cloud security groups 5. Reverse proxy misconfigured? Check nginx logs: /var/log/nginx/error.log 6. DNS pointing correctly? dig domain.com or nslookup
