在CentOS的LNMP環境中配置CDN加速，可參考以下步驟：
proxy_cache_path /data/wwwroot/caches/yourdomain.com levels=1:2 keys_zone=yourdomain:50m inactive=30m max_size=50m;
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://yourdomain.com;
proxy_cache yourdomain;
proxy_cache_valid 200 304 30m;
proxy_cache_valid 301 24h;
proxy_cache_valid 500 502 503 504 0s;
proxy_cache_valid any 1s;
proxy_cache_min_uses 1;

}
}
