The lighttpd-on-8080 configuration that dump1090-fa installs is a legacy thing more than anything, I suggest you just change the primary port of lighttpd to whatever you want to avoid conflicting with apache and throw away the 8080 config. Or put apache on a different port. Or write an apache config that serves the dump1090-fa data and don’t use lighttpd at all (it’s just a couple of aliases, basically - serve /usr/share/dump1090-fa/html/ as /dump1090-fa/ and /run/dump1090-fa/ as /dump1090-fa/data/)
Thanks @obj
Probably while you were writing this I realized it’s important that lighttpd not be listening on :8080. So I moved it to :90 and now dump1090 web interface displays fine, and lighttpd is out of apache’s way as well.
Later I’ll try to move dump1090 to apache. Meanwhile have to get more stuff running.
