sudo apt-get install juju-quickstart
sudo apt-get install juju-core
# to just show existing/default
# juju generate-config --show
juju generate-config
# edit to add your AWS KEYS
juju bootstrap
juju status
# assuming it shows a single machine numbered '0'
juju deploy mediawiki --to 0
# juju deploy cs:trusty/mediawiki-3

juju deploy mysql --to 0
juju add-relation mediawiki:db mysql
juju expose mediawiki
juju status
juju ssh

Make sure to obtain and assign an "elastic IP" so that the instance has a static IP

You can see what keys were added to the machine juju authorised-keys list and verify the key fingerprint for the key you want to use ssh-keygen -lf /home/user/.ssh/id_rsa

but you have to know/guess what user was installed by your charm

ssh -i /home/user/.ssh/id_rsa -o IdentitiesOnly=true -vvv ubuntu@ec2-55-5-555-55.compute-1.amazonaws.com
