Private Ethereum Network

Setup Node Zero

Create a new account for private net

$ geth --datadir "~/bether" account new

Create a private chain with the custom genesis block

$ geth --datadir "~/bether" init genesis.json

Launch node zero, a mining full node in cloud

$ geth --rpc --rpcport "8000" --rpccorsdomain "*" --datadir "~/bether" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --identity "zero" --networkid 666 --mine --minerthreads 1 console

To run in background with nohup

$ nohup geth --rpc --rpcport "8000" --rpccorsdomain "*" --datadir "~/bether" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --identity "zero" --networkid 666 --mine --minerthreads 1 > /dev/null &

To run in background with screen (CTRL+A then D for detaching), check geth.sh script

$ screen -dmS geth /usr/local/bin/geth --rpc --rpcport "8000" --rpccorsdomain "*" --datadir "~/bether" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --identity "zero" --networkid 666 --mine --minerthreads 1
$ screen -x geth

For attaching geth console

$ geth --datadir "/root/bether" attach ipc:/root/bether/geth.ipc console

Run eth.getBalance(eth.coinbase) command to check the (pre-allocated) account balance
Run admin.nodeInfo to get enode url (enode://xxxxx) and add ip address of the interface [::] to construct the complete enode address to share with other peers

"enode://6ad5934db83a0266c4c6d5048d02f86b3e69251d45ad411387cde9cc5a86030f2bee4bcbe200d4238d91b01c94444e562986058c9c4acca2a92cb81eb012acfc@192.168.2.41:30303?discport=0"

Setup Node One

Setup and launch node one: a non-mining full node

$ geth --datadir "~/bether" account new
$ geth --datadir "~/bether" init genesis.json
$ geth --rpc --rpcport "8000" --rpccorsdomain "*" --datadir "~/bether" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --identity "one" --networkid 666 console

Run admin.addPeer to connect node zero

> admin.addPeer("enode://6ad5934db83a0266c4c6d5048d02f86b3e69251d45ad411387cde9cc5a86030f2bee4bcbe200d4238d91b01c94444e562986058c9c4acca2a92cb81eb012acfc@192.168.2.41:30303")

Or create a <datadir>/static-nodes.json file that has the following format

[
  "enode://f4642fa65af50cfdea8fa7414a5def7bb7991478b768e296f5e4a54e8b995de102e0ceae2e826f293c481b5325f89be6d207b003382e18a8ecba66fbaf6416c0@33.4.2.1:30303",
  "enode://pubkey@ip:port"
]

Send ether from node zero to one using one's wallet address (do not forget to mine if you are the only node mining)

> personal.unlockAccount(eth.coinbase)
> eth.sendTransaction({from:eth.coinbase, to: '0xcb2a95f964acf8adee7fae30cf5dc6a3f5e14a5c', value: web3.toWei(.000000000001, "ether")})
> miner.start()
> miner.stop()

Setup Node Two

Setup and launch node two: a non-mining light node

$ geth --datadir "~/bether" account new
$ geth --datadir "~/bether" init genesis.json
$ geth --rpc --rpcport "8000" --rpccorsdomain "*" --datadir "~/bether" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --identity "two" --networkid 666 --light console
