以太坊私有链搭建
已实际操作测试验证，有问题可以一起探讨：个人有道笔记链接
以太坊私有链搭建
以太坊私有链环境搭建
http://www.it-jason.com/archives/395
先总体说一下步骤：
1.操作系统准备
2.golang安装
3.下载以太坊
4.安装以太坊
5.创世区块文件的准备
6.创世区块初始化
7.以太坊启动
创世区块文件

"gasLimit": "0xffffffff",
"config":{
"chainId":15,
"homesteadBlock":0,
"eip155Block":0,
"eip158Block":0
}
}chainId : 以太坊区块链网络Id，ethereum主链是1，私有链只用不要与主链冲突即可。
alloc : 预留账户，如下
“alloc”:{
“0x0000000000000000000000000000000000000001”:{“balance”:”121312321”},
“0x0000000000000000000000000000000000000002”:{“balance”:”121312321”},
}Coinbase: 旷工账户
Difficulty: 挖矿难度，0x400，这个是简单。
extraData：相当于备注
gasLimit：最小消耗gas
nonce : 64位随机数，用于挖矿，注意他和mixhash的设置需要满足以太坊黄皮书中的要求
parentHash : 上一个区块的Hash值，因为是创世块，石头里蹦出来的，没有在它前面的，所以是0
Timestamp : 时间戳
创世区块初始化

使用命令 geth -h 可以查看geth 相关的帮助文档。这里我说几个常用的属性。
--Identity : 节点身份标识，起个名字
--datadir : 指定节点存在位置，“data”
--rpc : 启用http-rpc服务器
--rpcapi : 基于http-rpc提供的api接口。eth,net,web3,db...
--rpcaddr : http-rpc服务器接口地址：默认“127.0.0.1”
--rpcport : http-rpc 端口(多节点时，不要重复)
--port : 节点端口号（多节点时，不要重复）
--networkid : 网络标识符 随便指定一个id（确保多节点是统一网络，保持一致）[root@host-10-72-77-171 bin]# geth --rpc --rpccorsdomain "*" --datadir "/root/blockchain/data" --port "30303" --rpcapi "db,eth,net,web3" --networkid 100000 console

多节点同步异常
问题1：不同节点时间不同步
解决办法：修改时间，同步问题2：同步异常
解决办法：停止多个节点挖矿，稍后启动
例如：若同步有异常或失败，可以重新启动节点再次尝试同步，成功后有类似打印

> 我们创建的simplestorage这个JavaScript变量仅仅在当前context中有效，如果我们将控制台关闭，再次打开控制台，这个变量将不复存在。那如何从新的控制台中创建出simplestorage这个变量呢？
我们回到第1步，编译那步。我们将使用编译结果中的ABI
> var abi = [ { "constant":false, "inputs":[ { "name":"x", "type":"uint256" } ], "name":"set", "outputs":[ ], "payable":false, "stateMutability":"nonpayable", "type":"function" }, { "constant":true, "inputs":[ ], "name":"get", "outputs":[ { "name":"", "type":"uint256" } ], "payable":false, "stateMutability":"view", "type":"function" }, { "constant":true, "inputs":[ ], "name":"getString", "outputs":[ { "name":"", "type":"string" } ], "payable":false, "stateMutability":"view", "type":"function" } ]
undefined

undefined
>
> simplestorage.
simplestorage._eth simplestorage.address simplestorage.constructor simplestorage.getString simplestorage.transactionHash
simplestorage.abi simplestorage.allEvents simplestorage.get simplestorage.set
> simplestorage.get()
99上面代码中我们创建出了simplestorage。其中，eth、contract()和at()都是以太坊提供的API。abi是我们之前创建的JavaScript变量，0x385d245f5f2e2e4ba256c05814a0972ba177e6fe是我们之前记住的智能合约的地址。也可以通过0x385d245f5f2e2e4ba256c05814a0972ba177e6fe
由于simplestorage仅仅是当前context中的一个变量，并不是需要写进区块链的数据，因此这个变量的创建不需要挖矿。后面的 就和之前一样的方式进行set和get操作
Mist / Ethereum-Wallet

安装Windows下Geth客户端
Windows必须64位系统，从官方网站下载编译好的win64客户端，解压缩即可运行，下载地址如下：
https://github.com/ethereum/go-ethereum/releases/ 下载后，只有一个Geth.exe的文件。安装图像化客户端Mist，依然是从官方地址下载编译好的客户端即可，下载地址：
https://github.com/ethereum/mist/releases/ 下载解压缩后，Ethereum-Wallet即为以太坊图形化界面。在Geth安装目录下放置初始化创世块文件，同Linux下的init.json一样，如果需要和linux下的节点连接起来，init.json内容必须一样。初始化的网络id也一样；
- 初始化创世块geth –datadir “%cd%\chain” init init.json; //%cd%：代表Geth安装目录
- 打开geth控制台geth -datadir “%cd%\chain” console
PS D:\05 BlockChain\Mist\geth> geth --identity "znv win etherum" --rpcaddr 0.0.0.0 --rpc --rpcport 8545 --maxpeers 5 --rpcapi "db,eth,net,web3,debug" --networkid 100 --datadir "C:\Program Files\Geth\chain" --port 30303 console

Q&A
Q1: Ethereum Wallet & Mist 差异
参考链接
- Mist DApp Browser
Mist is the browser for decentralized web apps. What Mozilla Firefox or Google Chrome are for the Web 2.0, the Mist Browser will be for the Web 3.0 (which will be decentralized).
Mist is still in heavy development (for instance it’s not recommended to visit untrusted DApps until the full security audit is done). You can find the releases to date here. The current release allows you to open any Ethereum DApp with the Mist Browser (with the disclaimer above).
- Ethereum Wallet DApp
All other releases of ‘Mist’ are no Mist releases at all, but a bundle of Mist Browser with a single DApp: The Ethereum Wallet, also known as the Meteor DApp Wallet.
These releases are therefore called Ethereum Wallet as it only offers a bundle of the Mist browser with a single DApp: the wallet.
The future, with Metropolis release, will provide a full Mist Browser able to open any DApp available out there. The Ethereum wallet will only be one among them.
Q2: Ethereum Wallet 节点数据存储路径修改
描述环境
安装Ethereum Wallet时，区块链文件存储目录是==C:\Users\Administrator\AppData\Roaming\Ethereum==，准备转移到==E:\Ethereum Wallet\Ethereum==。
剪切文件夹
==C:\Users\Administrator\AppData\Roaming\Ethereum==剪切到==E:\Ethereum Wallet\Ethereum==。切记，这里是剪切，如果==C:\Users\Administrator\AppData\Roaming\Ethereum==这个目录下还有“Ethereum”文件夹，会导致下一步的命令报错，“无法创建该文件”。
打开命令行窗口CMD，敲入命令，成功创建符号链接：
mklink /J "C:\Users\Administrator\AppData\Roaming\Ethereum" "E:\Ethereum Wallet\Ethereum"打开mist以太坊钱包，验证是否成功
Q3: windows Mist/wallet连接centos节点
PS C:\Program Files\Mist> .\Mist.exe --rpc http://10.72.77.171:8545ps：需要启动geth的时候加上“–rpc –rpcport 8545”启动参数
Mist 和 geth节点不在同一计算机运行时，可能同步会很慢，可以先停止geth挖矿，再启动
Q4: Mist钱包 无法连接节点
- 错误信息1：
Mist钱包 无法连接节点，查看日志获取更多信息
如果你遇到这个错，找到钱包的安装目录，双击启动，别用快捷方式那个图标启动了
或
PS C:\Program Files\Mist> .\Mist.exeQ4: Error starting protocol stack: Access is denied.
- 错误信息2：
Fatal: Error starting protocol stack: Access is denied.
解决办法：
https://ethereum.stackexchange.com/questions/10616/fatal-error-starting-protocol-stack-access-is-denied
This occurs when you have another instance of geth already running.
Use your Operating System’s process handler to end the process if there are no visible windows.
This happened to me when I started (and then closed) mist before I had set a private network running.
- 错误信息3(暂未解决)：
