# Put the caddy binary in the system wide binary directory and give it appropriate ownership and permissions:
sudo cp ${TEMP}/caddy /usr/local/bin
sudo chown root:root /usr/local/bin/caddy
sudo chmod 755 /usr/local/bin/caddy

# Give the caddy binary the ability to bind to privileged ports (e.g. 80, 443) as a non-root user:
sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/caddy

# Install the systemd service unit configuration file, reload the systemd daemon, and start caddy:
sudo cp ${TEMP}/init/linux-systemd/caddy.service /etc/systemd/system/
sudo chown root:root /etc/systemd/system/caddy.service
sudo chmod 644 /etc/systemd/system/caddy.service
sudo systemctl daemon-reload
sudo systemctl start caddy.service

# Have the caddy service start automatically on boot if you like:
sudo systemctl enable caddy.service
