This is already possible since the introduction of the database. You can put the database whereever you like to have it using FTL's config file (see FTL's README).
One of the reasons why Pi-hole is a very nice project also for Raspberry (and possibly also Linux) first-timers, is its simplicity. We really like to avoid additional gears that could break. This is also the main reason for why we decided to completely integrate SQLite into FTL instead of using some database server like MySQL. This is also the direction in which Pi-hole is currently developed:
- Currently:
dnsmasq(DNS) +FTL(statistics + database) +lighttpd(webserver) +PHP(API) - Next step:
FTL(DNS + statistics + database) +lighttpd(webserver) +PHP(API) - Future (already in active development):
FTL(DNS + statistics + database) + new API (web server + API)
As you can see, the number of gears that can break reduces and at the same time we ensure that we depend on less and less external software where we also cannot predict which versions will be provided by the various distributions out there.
