A way to run multiple nodes locally for testing:

  • Choose a unique port for each node you wish to run. e.g. 3 nodes with ports 6001, 6002, 6003

  • Create a file localhost-peers.txt, e.g.:

127.0.0.1:6001
127.0.0.1:6002
127.0.0.1:6003

  • Open a terminal shell for each node you wish to run.

  • Use the following invocation for each node:

PORT=6001; ./run-client.sh \
  -localhost-only \
  -disable-default-peers \
  -custom-peers-file=localhost-peers.txt \
  -download-peerlist=false \
  -launch-browser=false \
  -data-dir=/tmp/$PORT \
  -web-interface-port=$(expr $PORT + 420) \
  -port=$PORT

Replace PORT= with the correct port number.

This will run a node on $PORT with its own data-dir of /tmp/$PORT and expose the web API on $PORT + 420 (e.g. 6421).
