Geth
启动参考
连接主网
./geth --syncmode "light" --nousb --nodiscover --verbosity 1 console
//启动开发者模式
./geth --networkid 45 --dev --dev.period 1 --rpc --rpcapi "db,eth,net,web3,miner,personal" --verbosity 1 console
连接OKChain测试网
./geth --syncmode "light" --nousb attach [https://exchaintest.okexcn.com](https://exchaintest.okexcn.com/) console
运行参数参考
//生成一个新的帐号
./geth account new
//生成创世块
./geth init genesis.json
//启动1个线程进行挖矿
./geth --exec 'miner.start(1)' attach /root/.ethereum/geth.ipc
//查看本机帐户余额
./geth --exec 'eth.getBalance(eth.accounts[0])' attach /root/.ethereum/geth.ipc
//查看远程帐户余额
./geth --exec 'eth.getBalance(eth.accounts[0])' attach http://ip地址:8545
控制台命令参考
//查看帐户余额
eth.getBalance(eth.coinbase)
balance = web3.fromWei(eth.getBalance(eth.coinbase), "ether")
//解锁帐户(转帐前需先解锁)
>personal.unlockAccount(eth.accounts[0], "帐户密码")
//转帐
>eth.sendTransaction({from: "0xa66c7b8b1c26856d284a0b962385babe02caa51d", to: "0x3e822e05ee975e02be3f15f32b0fddced8d5bdd0", value: web3.toWei(0.1, "ether")})
或者
>personal.unlockAccount(eth.accounts[0])
>amount = web3.toWei(10, 'ether')
>eth.sendTransaction({from: eth.accounts[0], to: 收款地址, value: amount})
//查看挂起的交易(如为空[]，说明转帐已完成)
>eth.pendingTransactions
//查看某区块信息
eth.getBlock(0)
//查看某交易信息(hash id)
eth.getTransaction("0xdc6e22cf55db26a14486375e278712af8a19667f4541a8cca3d7ad67fcb5fad7")
//查看支持的智能合约编译器
eth.compile
//查看节点数量
net.peerCount
//使用1个线程挖矿(默认2个线程，并保存至coinbase)
miner.start(1)
//切换挖矿帐号
>miner.setEtherbase("0xdaa65af5d348c25266a5588148a9c0e9e4c056f8")
