k8s部署Ethereum以太坊私有网

先创建genesis.json

{
  "config": {
        "chainId": 10, 
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc"      : {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
  "difficulty" : "0x20000",
  "extraData"  : "",
  "gasLimit"   : "0x2fefd8",
  "nonce"      : "0x0000000000000042",
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
  "timestamp"  : "0x00"
}

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")
