Nginx

nginx

Nginx ops skill for configuring and operating Nginx as reverse proxy, web server, and ingress layer. Use for tasks like writing safe nginx.conf/server blocks, TLS, HTTP/2, caching, rate limiting, load balancing, observability, and troubleshooting 4xx/5xx, timeouts, and performance issues.

Full skill instructions

nginx

Use this skill for Nginx 配置、发布与故障排查（ops）。

Defaults / assumptions to confirm

Nginx distribution and version (open source vs Plus)
Deployment: bare metal/VM, Docker, or Kubernetes ingress-controller
TLS termination location and certificate management
Upstream architecture (services, ports, health endpoints)

Workflow

Understand traffic and requirements

Domains, paths, upstream services, expected QPS.
Timeouts, max upload size, websocket needs.
Caching requirements and security constraints.

Safe baseline config

Use explicit server_name, listen, and default_server strategy.
Set client_max_body_size intentionally.
Configure proxy_* headers correctly (Host, X-Forwarded-For, X-Request-Id).
Define error_page handling and static error responses if needed.

TLS / security

Use modern TLS settings; disable legacy protocols/ciphers.
Enable HSTS where appropriate.
Add basic security headers if not handled elsewhere.
Rate limit sensitive endpoints (login, OTP) with limit_req.

Performance

Enable gzip/brotli if appropriate.
Tune keepalive, buffers, and timeouts.
Use upstream keepalive and connection reuse.
Avoid expensive regex locations on hot paths.

Load balancing & resilience

Use upstreams with health checks (where available) and failover settings.
Configure retries carefully to avoid retry storms.
Support websocket upgrade when needed.

Observability

Access log format with request_id, upstream_time, status, bytes, user agent.
Error log level appropriate for production.
Export metrics if using nginx-prometheus-exporter or ingress metrics.

Troubleshooting checklist

4xx: routing, auth, body size, CORS, client IP headers.
5xx: upstream failures, timeouts, DNS issues, connection limits.
Timeouts: proxy_read_timeout, upstream latency, buffer/backpressure.
Performance: worker processes, file descriptors, CPU, TLS overhead.

Outputs

Proposed config snippets with rationale.
Rollout plan (test config, reload vs restart, rollback steps).
Debug report (symptom → evidence → root cause → fix).
