Deploy a test network of nodes¶

You can also run a local complex test network of peers easily; for instance, if you want to create a network with 4 nodes:

# Start the first node
contractvmd --data=~/test-node-data1 --port=5010 --api-port=8010

# Start the second node, bootstrap from first
contractvmd --data=~/test-node-data2 --port=5011 --api-port=8011 --seed=127.0.0.1:5010

# Start the third node, bootstrap from second
contractvmd --data=~/test-node-data3 --port=5012 --api-port=8012 --seed=127.0.0.1:5011

# Start the fourth node, bootstrap from first and third
contractvmd --data=~/test-node-data4 --port=5013 --api-port=8013 --seed=127.0.0.1:5010,127.0.0.1:5012

Now we have a local network of 4 nodes, accessible by clients from these host:port:

localhost:8010
localhost:8011
localhost:8012
localhost:8013

If a client application need to access to the local test network, you can fill one of these node pair; the bootstrap mechanism will automatically find the whole network of nodes.
