設 Nginx
設 Nginx 為網伺與反代附 SSL 終與安固。
用時
- 產中供靜檔(HTML、CSS、JS)
- 反代於後服(Node.js、Python、Go、R/Shiny)
- 以 Let's Encrypt 終 SSL/TLS
- 諸後例間載衡
- 加率限與安頭
入
- 必:部之目(Docker 容或裸機)
- 必:代之後服(host:port)
- 可選:SSL 之域名
- 可選:靜檔目
法
第一步:基反代
nginx.conf:
events { worker_connections 1024; } http { upstream app { server app:3000; } server { listen 80; server_name example.com; location / { proxy_pass http://app; 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; } } }
Docker Compose 服:
services: nginx: image: nginx:1.27-alpine ports: - "80:80" - "443:443" volumes: - ./nginx.conf:/etc/nginx/nginx.conf:ro depends_on: - app
得: 至 80 埠之請轉於 app 服。
第二步:靜檔之供
server { listen 80; root /usr/share/nginx/html; index index.html; location / { try_files $uri $uri/ /index.html; } location /assets/ { expires 1y; add_header Cache-Control "public, immutable"; } location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff2?)$ { expires 6M; add_header Cache-Control "public"; } }
第三步:SSL/TLS 以 Let's Encrypt
用 certbot 之 webroot 法:
server { listen 80; server_name example.com; location /.well-known/acme-challenge/ { root /var/www/certbot; } location / { return 301 https://$host$request_uri; } } server { listen 443 ssl; server_name example.com; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; ssl_protocols TLSv1.2 TLSv1.3; ssl_ciphers HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; location / { proxy_pass http://app; 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; } }
Docker Compose 附 certbot:
services: nginx: image: nginx:1.27-alpine ports: - "80:80" - "443:443" volumes: - ./nginx.conf:/etc/nginx/nginx.conf:ro - certbot-webroot:/var/www/certbot:ro - certbot-certs:/etc/letsencrypt:ro certbot: image: certbot/certbot volumes: - certbot-webroot:/var/www/certbot - certbot-certs:/etc/letsencrypt volumes: certbot-webroot: certbot-certs:
初證:
docker compose run --rm certbot certonly \ --webroot -w /var/www/certbot \ -d example.com --email admin@example.com --agree-tos
得: HTTPS 附有效 Let's Encrypt 證行。
敗則: 察 DNS 指伺。驗 80 埠為 ACME 挑戰開。
第四步:安頭
server { # ... SSL config above ... 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 "strict-origin-when-cross-origin" always; add_header Strict-Transport-Security "max-age=63072000; includeSubDomains" always; add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';" always; # Hide Nginx version server_tokens off; }
第五步:率限
http { # Define rate limit zones limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s; limit_req_zone $binary_remote_addr zone=login:10m rate=1r/s; server { location /api/ { limit_req zone=api burst=20 nodelay; proxy_pass http://app; } location /login { limit_req zone=login burst=5; proxy_pass http://app; } } }
第六步:載衡
upstream app { least_conn; server app1:3000; server app2:3000; server app3:3000 backup; }
| Method | Directive | Behavior |
|---|---|---|
| Round robin | (default) | Equal distribution |
| Least connections | | Routes to least busy |
| IP hash | | Sticky sessions |
| Weighted | | Proportional |
第七步:試設
# Test config syntax docker compose exec nginx nginx -t # Reload without downtime docker compose exec nginx nginx -s reload # Check response headers curl -I https://example.com
得:
nginx -t 報法 OK。頭含安頭。
驗
-
報設有效nginx -t - HTTP 重至 HTTPS(若 SSL 啟)
- 後服經代可達
- 應中含安頭
- 過請觸率限
- SSL Labs 試 A+(若公)
陷
- 缺
:後受誤主頭,破虛主與重。proxy_set_header Host
序要:Nginx 用最特配。精(location
)> 前綴(=
)> 正則(^~
)> 通前綴。~- SSL 證之更:設 cron 或計時行
而重載 Nginx。certbot renew - 大請體:默
為 1MB。傳大增之:client_max_body_size
。client_max_body_size 50m; - WebSocket 代:需額頭。見
之式。configure-reverse-proxy
參
- 多具代之式含 WebSocket 與 Traefikconfigure-reverse-proxy
- 含 Nginx 之 compose 棧setup-compose-stack
- 以 Nginx 為 SearXNG 前deploy-searxng
- K8s 入(NGINX Ingress 控)configure-ingress-networking
