On AWS for example, you may need to configure the “security group” for your server

to open port 80.

While we’ve got root access, let’s make sure the server has the key pieces of software we

sudo apt-get install git python3 python3-pip

elspeth@server

sudo pip3 install virtualenv

To confirm this works, we can rerun our functional tests and see that their failure mes‐

sages have changed slightly—one of them in particular should now mention Nginx:
