@Originalimoc 你遇到的问题是没有缓存文件吗？那你就是没有仔细文档。如果提示没权限，就touch一个cache，再chmod权限就行了。

设置cache定时保存

为避免cache因为系统或进程复位丢失，可以设置smartdns周期保存cache文件。 cache-checkpoint-time 86400

##############################################

Are you experiencing issues with missing cache files? If so, you might not have read the documentation carefully. If you get a permission denied error, just create a cache file using touch, then change the permissions with chmod.

Setting Cache Auto-Save

To prevent the cache from being lost due to system or process resets, you can configure SmartDNS to periodically save the cache file.

仔细看日志里ls -alF返回的权限
