# 使用 Nginx 部署 使用 Nginx 在您自己的伺服器上架設 BentoPDF。 ## 先決條件 - Ubuntu/Debian 伺服器 - 已安裝 Nginx - SSL 憑證(建議使用 Let's Encrypt) ## 步驟 1:建置專案 ```bash git clone https://github.com/alam00000/bentopdf.git cd bentopdf npm install npm run build ``` 若要自訂品牌,請在建置前設定環境變數: ```bash VITE_BRAND_NAME="AcmePDF" VITE_BRAND_LOGO="images/acme-logo.svg" npm run build ``` ## 步驟 2:複製檔案 ```bash sudo mkdir -p /var/www/bentopdf sudo cp -r dist/* /var/www/bentopdf/ sudo chown -R www-data:www-data /var/www/bentopdf ``` ## 步驟 3:Nginx 設定 建立 `/etc/nginx/sites-available/bentopdf`: ```nginx server { listen 80; server_name your-domain.com; return 301 https://$server_name$request_uri; } server { listen 443 ssl http2; server_name your-domain.com; # SSL Configuration ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem; root /var/www/bentopdf; index index.html; # Gzip compression gzip on; gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/wasm; gzip_min_length 1000; # WASM MIME type types { application/wasm wasm; } # Required headers for SharedArrayBuffer (LibreOffice WASM) # These must be on every response - especially HTML pages add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; add_header Cross-Origin-Resource-Policy "cross-origin" always; # Security headers add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Content-Type-Options "nosniff" always; add_header X-XSS-Protection "1; mode=block" always; # Pre-compressed LibreOffice WASM binary location ~* /libreoffice-wasm/soffice\.wasm\.gz$ { gzip off; types {} default_type application/wasm; add_header Content-Encoding gzip; add_header Cache-Control "public, immutable"; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } # Pre-compressed LibreOffice WASM data location ~* /libreoffice-wasm/soffice\.data\.gz$ { gzip off; types {} default_type application/octet-stream; add_header Content-Encoding gzip; add_header Cache-Control "public, immutable"; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } # Cache static assets location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|wasm)$ { expires 1y; add_header Cache-Control "public, immutable"; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } # SPA routing - serve index.html for all routes location / { try_files $uri $uri/ /index.html; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } } ``` ## 步驟 4:啟用網站 ```bash sudo ln -s /etc/nginx/sites-available/bentopdf /etc/nginx/sites-enabled/ sudo nginx -t sudo systemctl reload nginx ``` ## 步驟 5:使用 Let's Encrypt 設定 SSL ```bash sudo apt install certbot python3-certbot-nginx sudo certbot --nginx -d your-domain.com ``` ## 子目錄部署 若要架設在 `/pdf/`: ```nginx location /pdf/ { alias /var/www/bentopdf/; try_files $uri $uri/ /pdf/index.html; } ``` 建置方式: ```bash BASE_URL=/pdf/ npm run build ``` ## 效能調校 加入 `nginx.conf`: ```nginx http { # Enable sendfile sendfile on; tcp_nopush on; tcp_nodelay on; # Increase buffer sizes client_max_body_size 100M; # Worker connections worker_connections 2048; } ``` ## 疑難排解 ### WASM 無法載入 確認已設定 MIME 類型: ```nginx types { application/wasm wasm; } ``` ### 簽署 PDF 或表單填寫器顯示空白檢視器(`.mjs` MIME 錯誤) 如果瀏覽器主控台顯示: ``` Failed to load module script: The server responded with a non-JavaScript MIME type of "application/octet-stream". Strict MIME type checking is enforced for module scripts per HTML spec. ``` …且失敗的請求以 `.mjs` 結尾,表示您的 nginx 缺少 `.mjs → application/javascript` 對應。內建的 PDF 檢視器(簽署 PDF、表單填寫器及其他少數工具會使用)以 `.mjs` 副檔名提供 ES 模組檔案,而 nginx 預設的 `mime.types` 並未包含它們。 修正方法是在 `/etc/nginx/mime.types` 中現有的 `application/javascript` 那一行加上 `mjs`: ```nginx application/javascript js mjs; ``` > 請勿再新增*第二行* `application/javascript`:nginx 逐行解析 `mime.types`,且只有一個類型與副檔名的對應會生效,因此在某些版本中第二行會被默默忽略。請編輯現有的那一行,在 `js` 旁加上 `mjs`。 或在您的 server 區塊內進行本機覆寫(不需編輯全域檔案): ```nginx types { application/javascript js mjs; application/wasm wasm; } ``` 變更後重新載入 nginx: ```bash sudo nginx -t && sudo systemctl reload nginx ``` 確認方式:在瀏覽器開發者工具 → 網路分頁中,找到失敗的 `.mjs` 請求並檢查 `Content-Type` 回應標頭。現在它應該是 `application/javascript`,而不是 `application/octet-stream`。 ### Word/ODT/Excel 轉 PDF 無法運作 LibreOffice WASM 需要 `SharedArrayBuffer`,而這需要 `Cross-Origin-Embedder-Policy` 與 `Cross-Origin-Opener-Policy` 標頭。它也需要安全環境,因此 `http://localhost` 可用於本機測試,但 `http://192.168.x.x` 或其他區域網路 IP 通常需要 HTTPS。請注意,`location` 區塊中的 nginx `add_header` 指令會**覆寫**伺服器層級的 `add_header` 指令,兩者不會合併。每個有自己 `add_header` 的 `location` 區塊都必須包含 COEP/COOP 標頭。 使用以下指令驗證: ```bash curl -I https://your-domain.com/ | grep -i cross-origin ``` 如果在 nginx 前方使用反向代理,請確保它保留這些標頭。 ### 502 Bad Gateway 檢查 Nginx 錯誤記錄: ```bash sudo tail -f /var/log/nginx/error.log ```
