How to change port for lighttpd?

[Sjoerd22]

SO...to wrap it up ... WHAT is the preferred way of changing the port nr of lighttpd in 2025 ? Without too much, well, bashing about ?

[Bucking_Horn]

That would be a question for lighttpd support.

Pi-hole 6 comes with its own embedded webserver - it does not use lighttpd.

Bucking_Horn beat me to it ... again.
But here is anyway

You dont bc with Pi-hole version 6, lighttpd isnt installed as dependency anymore as was with version 5.
The pihole-FTL binary has a web daemon embedded called civetweb:

$ pstree -pst $(pidof -s pihole-FTL)
systemd(1)───pihole-FTL(4960)─┬─{civetweb-master}(22653)
                              ├─{civetweb-timer}(22652)
                              ├─{civetweb-worker}(22654)

                              ├─{civetweb-worker}(22657)
                              ├─{civetweb-worker}(22658)

You can alter the ports for HTTP or HTTPS via de webGUI "Expert" settings or via shell eg:

$ sudo pihole-FTL --config webserver.port
80o,443os,[::]:80o,[::]:443os

o = optional
s = secured via TLS (HTTPS)

$ sudo pihole-FTL --config webserver.port '8080o,4433os,[::]:8080o,[::]:4433os'
8080o,4433os,[::]:8080o,[::]:4433os

$ sudo ss -nltp | grep 'State\|pihole-FTL'
