systemd unit files

adduser --system aqua
adduser --system pool

aquachain.service

open up only 21303 tcp/udp firewall

(this unit file has unlocked account listening on 127.0.0.1:8543 only for automatic pool payout setups)

You must change: <your-pool-coinbase> to 0x1234...5678

Also: change '/dev/null' to some file with account password in it

caddy reverse proxy

listens on 80 tcp, 443 tcp/udp

(needed only to expose /api endpoint to view stats)

{
	log {

		output stderr
	}
}

:80 {
	respond 403
}

backup cron

something like

10 * * * * /usr/local/sbin/backup_redis.bash -cron

contents of /usr/local/sbin/backup_redis.bash:
