# 重启smartdns
/etc/init.d/smartdns restart

存成cloudflare.sh到usr目录，从 https://github.com/immortalwrt-collections/openwrt-cdnspeedtest/releases 下载你对应cpu的ipk直接解bin文件到usr目录，或者用原版，改应用程序名字，或者在链接中ipk直接装，改应用的位置。 再去弄个定时任务

50 4 * * * /bin/sh /usr/Cloudflare.sh

行了，每天4点50开始执行，替换20最快的ipv4和ipv6，smartdns开缓存和测速的话默认在20个里面选8个。222线程的话大概半个小时完成全过程
