准备工作

1. 一台没被Pixiv屏蔽的主机
2. 一个船新的域名(几级域都可以)

Nginx

这里仅列出关键配置，通常配置请自行添加

access_log off;

location ~ .* {
  proxy_pass https://i.pximg.net;
  proxy_cache_use_stale error timeout updating http_500 http_502 http_503 http_504;
  proxy_cache_lock on;
  proxy_cache_revalidate on;
  proxy_set_header Host i.pximg.net;
  proxy_set_header Referer "https://www.pixiv.net/";
  proxy_set_header Accept-Encoding "";
}
