使用 Nginx 部署 ​

使用 Nginx 在您自己的服务器上托管 BentoPDF。

前置条件 ​

  • Ubuntu/Debian 服务器
  • 已安装 Nginx
  • SSL 证书(推荐:Let's Encrypt)

步骤 1:构建项目 ​

bash
git clone https://github.com/alam00000/bentopdf.git
cd bentopdf
npm install
npm run build

如需自定义品牌,请在构建前设置环境变量:

bash
VITE_BRAND_NAME="AcmePDF" VITE_BRAND_LOGO="images/acme-logo.svg" npm run build

步骤 2:复制文件 ​

bash
sudo mkdir -p /var/www/bentopdf
sudo cp -r dist/* /var/www/bentopdf/
sudo chown -R www-data:www-data /var/www/bentopdf

步骤 3:Nginx 配置 ​

创建 /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;
    }
}

步骤 4:启用站点 ​

bash
sudo ln -s /etc/nginx/sites-available/bentopdf /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

步骤 5:使用 Let's Encrypt 配置 SSL ​

bash
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d your-domain.com

子目录部署 ​

要托管在 /pdf/:

nginx
location /pdf/ {
    alias /var/www/bentopdf/;
    try_files $uri $uri/ /pdf/index.html;
}

构建命令:

bash
BASE_URL=/pdf/ npm run build

性能调优 ​

添加到 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;
}

故障排除 ​

WASM 无法加载 ​

确保已设置 MIME 类型:

nginx
types {
    application/wasm wasm;
}

签署 PDF 或 Form Filler 显示空白查看器(.mjs MIME 错误) ​

如果浏览器控制台显示:

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.

……并且失败的请求以 .mjs 结尾,说明您的 nginx 缺少 .mjs → application/javascript 的映射。内置的 PDF 查看器(签署 PDF、Form Filler 和其他一些工具使用)附带扩展名为 .mjs 的 ES 模块文件,而 nginx 默认的 mime.types 不包含它们。

解决方法:在 /etc/nginx/mime.types 中,将 mjs 加到现有的 application/javascript 行:

nginx
application/javascript    js mjs;

请勿再追加第二行 application/javascript。nginx 逐行解析 mime.types,每种类型只有一个扩展名映射生效,因此在某些版本中第二行会被静默忽略。请编辑现有的行,把 mjs 与 js 放在一起。

或者在您的 server 块内局部覆盖(无需修改全局文件):

nginx
types {
    application/javascript js mjs;
    application/wasm wasm;
}

修改后重新加载 nginx:

bash
sudo nginx -t && sudo systemctl reload nginx

确认方法:在浏览器开发者工具的 Network 标签中,找到失败的 .mjs 请求并检查 Content-Type 响应标头。它现在应为 application/javascript,而不是 application/octet-stream。

Word/ODT/Excel 转 PDF 无法使用 ​

LibreOffice WASM 需要 SharedArrayBuffer,而这需要 Cross-Origin-Embedder-Policy 和 Cross-Origin-Opener-Policy 标头。它还需要安全上下文,因此 http://localhost 可用于本地测试,但 http://192.168.x.x 或其他局域网 IP 通常需要 HTTPS。请注意,location 块中的 nginx add_header 指令会覆盖server 级别的 add_header 指令,而不是合并。每个带有自己 add_header 的 location 块都必须包含 COEP/COOP 标头。

验证方法:

bash
curl -I https://your-domain.com/ | grep -i cross-origin

如果 nginx 前面有反向代理,请确保它保留这些标头。

502 Bad Gateway ​

查看 Nginx 错误日志:

bash
sudo tail -f /var/log/nginx/error.log
