1.create account address with password
geth --datadir=$datadir account new

2.prepare genesis.json and also allocate ether token to my created account
you can modify this genesis.json with the following principal as your dev network:
- lower difficulty
 - raise up gasLimit
 
{
  "nonce": "0x0000000000000042",
  "difficulty": "0x4000",
  "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",

  },
  "alloc": {

    }
  }
}
3.init chaindata with genesis.json
geth --datadir $datadir init genesis.json
4.start a miner to start process future transactions. By lower gasprice, so our tx won't hit the gasLimit easily.
geth  -rpc --rpcapi "admin,eth,miner,net,personal,web3" --datadir $datadir --mine --gasprice 1000
5.use console mode to unlock my account. so we are good to go to transfer token and deploy contracts
geth attach $ipcpath console
