# 这段配置的作用是 匹配任意域名，子域名(subdomain)、主域名(maindomain)、顶级域名(tld) , 子域名可有可无 
# 然后根据匹配值 将root路径设置为 匹配到的值($host)
	## server
	server_name ~^(?:(?<subdomain>.+)\.)?(?<maindomain>[^\.]+)\.(?<tld>.+)$;

    set $root_path /data/wwwroot/$host;

    if (!-d $root_path){
        set $root_path /data/wwwroot/www.$host;
    }

    root $root_path;
