RecoveryFromUEFI

Use archlinux installation disk for entering the command line, then:

mkdir /mnt/arch
mount -t auto /dev/sda2 /mnt/arch
mount -t auto /dev/sda1 /mnt/arch/boot/
arch-chroot /mnt/arch

Re-install grub:

grub-install --efi-directory=/boot/efi --target=x86_64-efi /dev/sda

Then reboot the machine we could see the archlinux reback again.

CaddyStaticServer

Install canddy on rpi via:

# sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https -y
# apt-cache search caddy
# curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
# sudo apt update
# sudo apt-get install caddy -y

Configuration files:

$ cat /etc/caddy/Caddyfile 
# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

:80 {
	# Set this path to your site's directory.
	root * /media/sda/ucc
	# Enable the static file server.
	file_server browse {
	hide .git
}

basicauth * {
cwgo gowugowuoguwougowugouwogue
}
	# Another common task is to set up a reverse proxy:
	# reverse_proxy localhost:8080

	# Or serve a PHP site through php-fpm:
	# php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

The password could be generated via caddy hash-password.

Reload the server:

$  sudo systemctl reload caddy
