+# 生产环境部署
+
+本文档介绍如何将 AI Video Assistant 部署到生产环境，包括 Nginx 配置、SSL 证书、性能优化等。
+
+## Nginx 部署
+
+### 1. 构建前端
+
+```bash
+cd web
+npm run build
+```
+
+### 2. 部署静态文件
+
+```bash
+sudo mkdir -p /var/www/ai-assistant
+sudo cp -r dist/* /var/www/ai-assistant/
+```
+
+### 3. 配置 Nginx
+
+创建 `/etc/nginx/sites-available/ai-assistant`：
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+    root /var/www/ai-assistant;
+    index index.html;
+
+    # Gzip 压缩
+    gzip on;
+    gzip_types text/plain text/css application/json application/javascript;
+
+    # 静态文件缓存
+    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
+        expires 30d;
+        add_header Cache-Control "public, immutable";
+    }
+
+    # SPA 路由支持
+    location / {
+        try_files $uri $uri/ /index.html;
+    }
+
+    # API 反向代理
+    location /api {
+        proxy_pass http://localhost:8080;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+    # WebSocket 代理
+    location /ws {
+        proxy_pass http://localhost:8000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header Host $host;
+        proxy_read_timeout 86400;
+    }
+}
+```
+
+### 4. 启用站点
+
+```bash
+sudo ln -s /etc/nginx/sites-available/ai-assistant /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+## SSL 证书配置
+
+### 使用 Let's Encrypt
+
+```bash
+# 安装 certbot
+sudo apt install certbot python3-certbot-nginx
+
+# 申请证书
+sudo certbot --nginx -d your-domain.com
+
+# 自动续期
+sudo certbot renew --dry-run
+```
+
+### HTTPS 配置
+
+```nginx
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # SSL 安全配置
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_prefer_server_ciphers on;
+    ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256;
+
+    # HSTS
+    add_header Strict-Transport-Security "max-age=31536000" always;
+
+    # ... 其他配置同上
+}
+
+# HTTP 重定向到 HTTPS
+server {
+    listen 80;
+    server_name your-domain.com;
+    return 301 https://$server_name$request_uri;
+}
+```
+
+## 性能优化
+
+### Nginx 优化
+
+```nginx
+# 在 http 块中添加
+worker_processes auto;
+worker_connections 1024;
+
+# 开启 sendfile
+sendfile on;
+tcp_nopush on;
+tcp_nodelay on;
+
+# 缓冲区设置
+client_body_buffer_size 10K;
+client_header_buffer_size 1k;
+client_max_body_size 8m;
+```
+
+### 静态资源 CDN
+
+如果使用 CDN，修改构建配置：
+
+```env
+# .env.production
+VITE_CDN_URL=https://cdn.your-domain.com
+```
+
+## 监控与日志
+
+### 访问日志
+
+```nginx
+access_log /var/log/nginx/ai-assistant.access.log;
+error_log /var/log/nginx/ai-assistant.error.log;
+```
+
+### 日志轮转
+
+```bash
+# /etc/logrotate.d/nginx
+/var/log/nginx/*.log {
+    daily
+    rotate 14
+    compress
+    delaycompress
+    missingok
+    notifempty
+}
+```
+
+## 备份策略
+
+### 数据库备份
+
+```bash
+# PostgreSQL 备份
+pg_dump -U postgres ai_assistant > backup_$(date +%Y%m%d).sql
+
+# 定时备份（crontab）
+0 2 * * * pg_dump -U postgres ai_assistant > /backups/backup_$(date +\%Y\%m\%d).sql
+```
+
+## 高可用部署
+
+对于高可用需求，建议：
+
+1. **负载均衡** - 使用 Nginx upstream 或云负载均衡
+2. **数据库主从** - PostgreSQL 主从复制
+3. **Redis 集群** - 会话和缓存高可用
+4. **健康检查** - 定期检测服务状态
