Where do my websites go?

The default site is /srv/www/localhost.

If you own a domain (say example.com) then you should put a new folder in /srv/www (such as /srv/www/example.com) and then edit /etc/caddy/Caddyfile to include a config such as this:

https://example.com {
  root /srv/www/example.com
}
https://www.example.com {
  redir https://example.com
}

Start caddy on boot

Startup Scripts are installed by the installer :)

• systemd (Ubuntu, Fedora, Arch, etc)
• launchd (OS X, macOS, Darwin)

Caddy should begin running on ports 80 and 443 as soon as you install it and should automatically start on boot

Caveats

all platforms

go (in which caddy is written) doesn't support privilege deescalation (running on root to bind to port 80 and 443 and then switching to a non-root user).

This isn't usually a problem, however, because the launchers (systemd et al) usually do.

darwin / macOS / OS X

• launchd doesn't support privilege deescalation
• authbind doesn't work on recent versions of OS X

However, you can use ipfw to locally port-forward.

Also, launchd is a pain to configure. There's not much in the way of official documuntation... but there is some great unofficial documentation and LaunchControl (direct download) makes it actually quite easy. (ignore that the site looks like a 90s spam site - much like MakeMKV - it's actually legit)

Debugging systemd

sudo -u www-data CADDYPATH=/etc/ssl/caddy /usr/local/bin/caddy -log stdout -agree=true -conf=/etc/caddy/Caddyfile -root=/var/tmp
