先创建genesis.json

        "chainId": 10, 
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc"      : {},

测试

curl http://172.16.0.12:30087
geth attach http://172.16.0.12:30087
personal.newAccount('12345678')
personal.unlockAccount(eth.accounts[1], "12345678", 15000)
miner.start()


概念和命令

概念

eth:包含一些跟操作区块链相关的方法
net:包含以下查看p2p网络状态的方法
admin:包含一些与管理节点相关的方法
miner:包含启动&停止挖矿的一些方法
personal:主要包含一些管理账户的方法
txpool:包含一些查看交易内存池的方法
web3:包含了以上对象,还包含一些单位换算的方法

用于开始挖掘的常见命令

创建新帐户 : personal.newAccount(‘12345678’) #密码 0x539bcbb3dfc0c06ca9166325bfb6b1bfa51569b3
解锁帐户 : personal.unlockAccount(web3.eth.coinbase, “123456”, 15000)
开始挖掘 : miner.start()
停止挖掘 : miner.stop()

执行设置miner地址:

miner.setEtherbase(eth.coinbase)
true

也可以执行执行以下命令进行设置:

miner.setEtherbase(eth.accounts[0])
true

初始化创世区块: geth init ./genesis.json –datadir “D:\Eth”
启动节点:geth –datadir “D:\Eth” –networkid 10 –port 30303 –rpc –rpcaddr 127.0.0.1 –rpcapi “db,eth,personal,net,web3” –allow-insecure-unlock console
开始挖矿:miner.start() miner.stop()
账户余额:eth.getBalance(“地址”)

创建账户:personal.newAccount(“”);
“0xf1c4dabd99003feaef5bff65658bf5976627e3fa” 0
“0xccc915534b908fcb4e1ee9063e5b1d0d3be5672d” 1

账号列表:eth.accounts
解锁账号:personal.unlockAccount(eth.accounts[5],””,0) 启动–allow-insecure-unlock
定义数量:amount = web3.toWei(50,’ether’)

转账:eth.sendTransaction({from:eth.accounts[0],to:””, value:amount})

挖矿奖励账户:eth.coinbase miner.setEtherbase(eth.accounts[1])

交易池状态:txpool.status
获取区块:eth.getBlock()
获取交易信息:eth.getTransaction(“0xbee5007e38adf954f8a6cf699f771d39c9c8235920d71b6f96d66c72254d7724”)
