　    一键部署OpenClaw        CDN的原理很简单：把你的静态文件（图片、CSS、JS）复制到全国各地的节点，用户访问时从最近的节点取数据，不用每次都回源站取。

B |     国外CDN首选Cloudflare，免费版功能很强：DDoS防护、SSL证书、页面规则、压缩。缺点是国内访问速度一般，有时候比不上CDN还慢。    国内CDN选择多：阿里云CDN、腾讯云CDN等等。国内用户访问快，但多数需要备案的域名才能接入。    # Cloudflare接入步骤    1. 注册Cloudflare账号，添加你的域名    2. Cloudflare会给你两个NS服务器地址    3. 去域名注册商后台，把NS服务器改成Cloudflare的    4. 等待DNS生效（一般30分钟到数小时）    5. 在Cloudflare后台开启：    - SSL/TLS: Full    - Always Use HTTPS: On    - Auto Minify: 勾选HTML/CSS/JS    - Brotli: On    如果用国内CDN，需要在DNS解析里加CNAME记录指向CDN分配的地址，然后在CDN后台配置回源地址（你的服务器IP）。    # Nginx配置回源（当CDN回源请求时返回正确内容）    server {    listen 80;    server_name www.yoursite.com;    root /www/wwwroot/yoursite;    # 配置回源Host头，让CDN能正确回源    set_real_ip_from 0.0.0.0/0;    real_ip_header X-Forwarded-For;    location ~* \.(jpg|jpeg|png|gif|css|js|svg|woff2)$ {    expires 30d;    add_header Cache-Control "public";    add_header Access-Control-Allow-Origin "*";    }    }    选哪个？流量以国内为主就用国内CDN；海外流量多就用Cloudflare；预算充足就两个都接，国内外都快。
