The following environment variables are required: COIN - see lib/coins.py, must be a coin NAME NETWORK - see lib/coins.py, must be a coin NET DB_DIRECTORY - path to the database directory (if relative, to run script) USERNAME - the username the server will run as SERVER_MAIN - path to the server_main.py script (if relative, to run script) In addition either RPC_URL must be given as the full RPC URL for connecting to the daemon, or you must specify RPC_HOST, RPC_USER, RPC_PASSWORD and optionally RPC_PORT (it defaults appropriately for the coin and network otherwise). The other environment variables are all optional and will adopt sensible defaults if not specified.
