Ubuntu

安装客户端

1.源码安装(需go环境支持)

git clone https://github.com/ethereum/go-ethereum.git
cd  go-ethereum
git checkout v1.7.2
make geth
make all

2.直接安装

apt-get update
apt-get install software-properties-common
add-apt-repository -y ppa:ethereum/ethereum
apt-get update
apt-get install ethereum

安装Solidity 编译器

apt-get install npm
npm install -g solc

私链配置及初始化

新建genesis.json文件并添加如下内容

{
"config": {
    "chainId": 10,
    "homesteadBlock": 0,
    "eip155Block": 0,
    "eip158Block": 0
    },
"nonce":"0x0000000000000042",
"mixhash":"0x0000000000000000000000000000000000000000000000000000000000000000",
"difficulty": "0x4000",
"alloc": {},
"coinbase":"0x0000000000000000000000000000000000000000",
"timestamp": "0x00",

"extraData": "0x88",
"gasLimit":"0xffffffff"
}

geth  --datadir "$basepath/chain" init genesis.json
#成功提示Successfully wrote genesis...
geth --identity "0x88" --rpc --rpccorsdomain "*" --datadir "$basepath/chain" --port "30303" --rpcapi "db,eth,net,web3" --networkid 95518 console  
#进入geth交互控制台，后台运行geth attach http://127.0.0.1:8545进入控制台
> personal.newAccount()
#生成新账户
> miner.start()
#开始挖矿

部署合约

新建合约testContract.sol添加测试代码

pragma solidity ^0.4.0;
contract test
{
   uint storedData;
   function set(uint x) public {
        storedData = x;
    }

    function get() public view returns (uint) {
        return storedData;
    }
}

#生成bin文件
solcjs --bin testContract.sol
#生成abi文件
solcjs --abi testContract.sol

记下bin和abi文件内容，返回geth控制台

#发送合约

#如果没挖矿txpool.status查看是否有待确认交易，eth.getBlock("pending", true).transactions查看信息,启动挖矿后交易确认可以执行合约

调用合约

> contract.set(123,{from:eth.accounts[0]})
> contract.get({from:eth.accounts[0]})
#调用get可以看到返回123
