# 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
|
||
```
