blockchain_go how to send amount?

when I send amount on mac os: $ ./blockchain_go send -from 18LzaPoMWzHb4fozkp1AJeiomjQBSTMshY -to 15qAH88JWPzv7D1cKz4xj63NXse4WDZiGU -amount 1

I received the error: 2018/02/09 15:52:57 sendTx to addr (localhost:3000) localhost:3000 is not available,err = dial tcp [::1]:3000: getsockopt: connection refused Success!

what can I do?

You need to start other nodes, specifically one with NODE_ID=3000. This point is described in: https://jeiwan.cc/posts/building-blockchain-in-go-part-7/

I have similar problem with this scenario. After this line: NODE 3002 Quickly! Switch to the miner node and see it mining a new block! Also, check the output of the central node.

I have good (perhaps) output for NODE 3002 (MINER node): Received inv command Recevied inventory with 1 tx Received tx command

But NODE 3000 (CENTRAL node) had no output, just error: Received tx command localhost:3001 is not available Received getdata command

After this I had started WALLET node: Starting node 3001

and it didn't download mined block! So I got old balances.
