本篇文章介紹通過truffle來部署智能合約欧漱。
1留夜、首先需要有一個聯盟鏈quorum的環(huán)境，如上篇文章所示蒋搜。
2册着、部署合約，這里介紹兩種方法逃顶，一是教程里的使用solc編譯讨便，獲取編譯后的abi和bytecode充甚，然后在geth控制臺里部署；第二種方法是使用truffle直接部署霸褒。
下面分別介紹：
（1）使用solc編譯
智能合約文件：simplestorage.sol
pragma solidity ^0.4.15;
contract simplestorage {
? uint public storedData;
functionsimplestorage(uint initVal)public{
? ? storedData = initVal;
? }
functionset(uint x)public{
? ? storedData = x;
? }
functionget()constantpublicreturns(uint retVal){
returnstoredData;
? }
}
編譯：
solcjs --bin --abi simplestorage.sol
會生成兩個文件：?simplestorage_sol_simplestorage.abi 和 simplestorage_sol_simplestorage.bin分別是abi和bytecode伴找，在部署時會用到。（或者使用在線編譯器remix废菱，更加方便）
然后進入geth客戶端（第一個節(jié)點）：
geth attach qdata/dd1/geth.ipc
然后在部署合約和調用合約：
>varabi = [{"constant":true,"inputs":[],"name":"storedData","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"x","type":"uint256"}],"name":"set","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"get","outputs":[{"name":"retVal","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[{"name":"initVal","type":"uint256"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]
undefined

>varsimpleContract = web3.eth.contract(abi);
undefined
> simpleContract.new(42, {from:web3.eth.accounts[0],data: bytecode,gas:0x47b760,privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
{
abi: [{

}
部署成功技矮，其中simpleContract.new中
privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]}
是指明這個合約是私有合約，只有創(chuàng)建合約的節(jié)點1和地址代表的節(jié)點7可以正常調用殊轴。下面節(jié)點1調用合約衰倦，需要用地址和abi來加載已經部署好的合約，其中地址在日志文件/qdata/logs/1.log中旁理，找到這么一行：
INFO [06-07|19:57:38] Submitted contract creation? ? ? ? ? ? ? fullhash=0x5c7fc60d8370bed6eb14e3f776365f77806eda9653e6a3f682827f68e056c0f8to=0x4D3bfd7821E237fFE84209d8E638f9f309865b87
to后面的地址就是合約的地址樊零，
>varprivate = eth.contract(abi).at("0x4D3bfd7821E237fFE84209d8E638f9f309865b87")
undefined
> private.get()
42
然后節(jié)點2調用合約，同樣需要地址和abi來加載合約韧拒，執(zhí)行結果：
> private.get()
0
節(jié)點7執(zhí)行合約：
> private.get()
42
然后在節(jié)點1調用set淹接，改變數值：
> private.set(65656, {from:eth.coinbase,privateFor:["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
"0xb42a5483ef98f6a7b3dc35d7ffaaf0170360de63fb7d14c8514532906fb10395"
> private.get()
65656
同樣在節(jié)點2和節(jié)點7獲取修改的值，結果分別為0和65656
到此叛溢，部署和調用智能合約結束塑悼。
（2）下面介紹使用truffle來部署智能合約(這里使用truffle主要是編譯和部署合約)
新建一個目錄test，然后進入目錄初始化一個truffle項目：
truffle init
然后在contracts目錄中編寫智能合約：
pragma solidity ^0.4.15;
contract simplestorage {
? uint public storedData;
functionsimplestorage(uint initVal)public{
? ? storedData = initVal;
? }
functionset(uint x)public{
? ? storedData = x;
? }
functionget()constantpublicreturns(uint retVal){
returnstoredData;
? }
}
在test目錄下編譯合約：
truffle compile
部署合約：
在migrations文件夾里添加新的部署文件：
2_deploy_simplestorage.js
varsimple_storage = artifacts.require("SimpleStorage");
module.exports =function(deployer){
deployer.deploy(simple_storage,123, {privateFor:["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]});
};
修改truffle.js文件：
module.exports = {
networks: {
development: {
host:"localhost",
port:22000,
network_id:"*",
gas:4600000,
gasPrice:0
? ? ? ? },
second_node: {
host:"localhost",
port:22001,
network_id:"*",
gas:4600000,
gasPrice:0
? ? ? ? },
third_node: {
host:"localhost",
port:22002,
network_id:"*",
gas:4600000,
gasPrice:0
? ? ? ? },
forth_node: {
host:"localhost",
port:22003,
network_id:"*",
gas:4600000,
gasPrice:0
},
fifth_node:{
host:"localhost",
port:22004,
network_id:"*",
gas:4600000,
gasPrice:0
},
sixth_node: {
host:"localhost",
port:22005,
network_id:"*",
gas:4600000,
gasPrice:0
},
seventh_node: {
host:"localhost",
port:22006,
network_id:"*",
gas:4600000,
gasPrice:0
? }
? ? }
};
在test目錄下執(zhí)行命令：truffle migrate --network development --reset
>truffle migrate --network development --reset

其中倒數第四行中是合約的地址楷掉。
3厢蒜、進入geth控制臺
geth attach qdata/dd1/geth.ipc
合約地址和abi加載合約，再調用烹植。這里就和上面方法一樣了斑鸦，不再重復。
