pi-hole出现attempt to write a readonly database

这是由于安装了nigix出现的问题：

You need to allow the user or group that nginx is running as, to have write permissions on all the .db files under /etc/pihole. In my case, that’s the www-data group, so I do:

sudo chown -R pihole:www-data /etc/pihole
sudo chmod g+w /etc/pihole/*.db

and that fixes it.
