Running vagrant provision sets up haproxy which will listen on 3311.

From the host, start a netcat server:

mediawiki-vagrant $ nc -k -vl 127.0.0.1 9999

From vagrant, connect netcat to haproxy:

vagrant@mediawiki-vagrant:/vagrant/puppet$ nc localhost 3311

If haproxy errors:

haproxy[9115]: proxy mariadb-s1 has no server available!

Ensure the netcat server is running, and restart haproxy:

sudo systemctl restart haproxy
