安装

brew tap ethereum/ethereum
brew install ethereum

初始化

mkdir ~/geth
cd geth
vim genesist.json

问题1

}

geth --datadir ~/geth/data init ~/geth/genesist.json

问题2
Fatal: Failed to start the JavaScript console: api modules: Post "http://localhost:8545": dial tcp 127.0.0.1:8545: connect: connection refused

问题4
Error: account unlock with HTTP access is forbidden at web3.js

geth --datadir ~/geth/data --networkid 666 console --rpc --rpcport 8545 --rpcaddr 127.0.0.1 --rpc --rpcapi eth,web3,personal --allow-insecure-unlock  2>>~/geth/logs.txt

问题3
etherbase missing: etherbase must be explicitly specified

eth.accounts
miner.setEtherbase("0x......")
miner.getHashrate()
miner.stop()

转账

user1=eth.accounts[0]
user2=eth.accounts[1]
eth.sendTransaction({from: user1,to: user2,value: web3.toWei(3,"ether")})

Error: authentication needed: password or unlock

personal.unlockAccount('0xdb161745f122affbd2edd7f801d23c1968a3e18a','123456')

上面已经提示转帐成功了，但是user2帐户余额依然是0，是因为没有矿工来挖矿处理，我们启动一个矿工

新窗口连接

geth attach http://localhost:8545
eth.getBalance(eth.accounts[0])
