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
