vagrant plugin install vagrant-omnibus
vagrant up
vagrant ssh
Then, in the VM:
journalctl -o short-monotonic -p7 -f --full
/bin/stunnel /etc/stunnel/server.conf
systemctl start nginx
systemctl daemon-reload; systemctl stop stunnel.socket; systemctl stop stunnel.service; systemctl start stunnel.socket; curl localhost:9999
