使用 Nginx 作为反向代理并开启缓存提高网站性能

# 设置代理缓存路径位置，最大大小为1g
proxy_cache_path  /etc/blog_cache  levels=1:2 keys_zone=blogcache:100m inactive=24h max_size=1g;

		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Proto https;
		proxy_pass http://127.0.0.1:2368;

		# 删除对匿名访问者无效的cookies并阻止缓存
