# 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
|
||
```
