I use Gophernicus on Debian as my Gopher
server. Here is how I set it up:

1 Install Gophernicus
2 Configure /etc/default/gophernicus
3 Enable gophernicus.socket with systemctl
4 Open port 70, e.g. in /etc/nftables.conf

For step 2, I wrote something like the
following into /etc/default/gophernicus,
but without the line breaks:

 OPTIONS='-h example.com
          -r /home/me/gopher
          -nv -nh -nf -no -nq -na
          -nt -np -nx -nu -nH'

When I configured Gophernicus on my
system, the man page synopsis, the man
page body text, and the usage output
("sudo gophernicus -?") disagreed about
the existence of -nu and -nH. I have
compiled the following descriptions:

 From the usage output (-?):
  -nv  Disable virtual hosting
  -nl  Disable parent directory links
  -nh  Disable menu header (title)
  -nf  Disable menu footer
  -nd  Disable dates and filesizes in
        menus
  -nc  Disable file content detection
  -no  Disable charset conversion for
        output
  -nq  Disable HTTP-style query strings
        (?query)
  -ns  Disable logging to syslog
  -na  Disable autogenerated caps.txt
  -nt  Disable /server-status
  -nm  Disable shared memory use (for
        debugging)
  -nr  Disable root user checking (for
        debugging)
  -np  Disable HAproxy proxy protocol
  -nx  Disable execution of gophermaps and
        scripts
  -nu  Disable personal gopherspaces

 From the man page body text:
  -nH  Disable HTTP response to HTTP GET
        and POST requests
