初始化創(chuàng)世區(qū)塊
./go-ethereum/build/bin/geth -datadir ./data/ init ./genesis.json
啟動以太坊網(wǎng)絡 指定RPC通訊端口
./go-ethereum/build/bin/geth -datadir ./data/ --networkid 10 --rpc --rpcaddr localhost --rpcport "8545" console
設置挖礦賬戶 開始挖礦
miner.setEtherbase(eth.accounts[0])
miner.start(1)//設置了挖礦的線程數(shù)目
利用web3測試

}
安裝依賴
npm install
編寫測試腳本
index.js
const fs = require("fs");
const solc = require('solc')
const net = require('net')
/// 引入web3 庭砍，版本 0.20.4
let Web3 = require('web3');
let web3;
if (typeof web3 !== 'undefined') {
web3 = new Web3(web3.currentProvider);
} else {
// set the provider you want from Web3.providers
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
}
//區(qū)塊查詢
console.log(web3.eth.accounts[0])
web3.eth.getBlock(1, function(error, result){
if(!error){
console.log(result)
}
else{
console.log(error);
}
})
停止挖礦
miner.stop()
查詢網(wǎng)絡端口
netstat -nlp | grep eth
