Jeopardy

To start your Phoenix server:

• npm install --prefix ./assets
• Run mix setup to install and setup dependencies
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

Prod config with systemd

I use systemd to run the service so that restarts and log files are handled in a standard way.

• Write this file to /etc/systemd/system/jeopardy.service
• Append necessary environment variables to /etc/environment
• After each change to the jeopardy.service config file: sudo systemctl daemon-reload
• Start the service: sudo systemctl start jeopardy
• Stop the service: sudo systemctl stop jeopardy
• Tail logs: sudo journalctl -f -u jeopardy
