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
