以太坊（Ethereum）是一个运行智能合约的去中心化平台（Platform for Smart Contract），平台上的应用按程序设定运行，不存在停机、审查、欺诈、第三方人为干预的可能。以太坊平台由Golang、C++、Python 等多种编程语言实现。

前段时间的The DAO事件让以太坊平台损失惨重，以太坊也分裂成ETC和ETH，平台的发展前景不明。

## 2.开始安装 ##

### 2.1选择测试网络 ###

![1241225-20170921162449290-507499540.png][]

前期选测试网络， 后期再讲主干网络

### 2.2输入密码 ###

密码不能忘记

网络好的情况下需要1小时， 我用了2个半小时

### 2.3注意 ###

很多同学反映马上下载完成了， 就不动了。 这个时候果断关闭然后重新打开，OK 。 出现如下界面

### 2.4 安装完成，进入主界面 ###

## 3. 开启以太坊挖矿 ##

这一步骤需要调用后台命令geth 操作

geth的全称是go-ethereum,是一个以太坊客户端,用go语言编写,应该是目前最常用的客户端

### 3.1找到geth 命令 ###

找到目录： C:\\Users\\zzy\\AppData\\Roaming\\Ethereum Wallet\\binaries\\Geth\\unpacked

找不到的把zzy 换成Administrator 试试。

注意：请将隐藏文件显示。不会请自行百度。

### 3.2 在Geth安装目录下放置初始化创世块文件genesis.json ###

Genesis.json内容：（先不考虑什么意思， 以后会讲）

### 3.3初始化创世块 ###

在C盘建立一个空文件夹 C:\\ethereum

命令：geth --datadir "C:\\ethereum" init genesis.json

注意：geth 命令需要设置环境变量才能用， 如果不会设置，直接cd 到 C:\\Users\\zzy\\AppData\\Roaming\\Ethereum Wallet\\binaries\\Geth\\unpacked 目录使用：

如下：

![1241225-20170921164422181-340229410.png][]

OK ，出现上图信息表示运行成功，后查看 C:\\ethereum 目录多了几个文件：

![1241225-20170921164539056-1382830655.png][]

### 3.4启动私链 ###

命令如下：

![1241225-20170921164815212-796320187.png][]

出现上图所示，为启动成功

如果启动不成功， 先关闭以太坊客户端，再试。

### 3.5 开始挖矿 ###

命令：

#### 3.5.1 新建 一个账户 ####

personal.newAccount(‘123.abc’) 新建 一个账户

![1241225-20170921165211806-1113232838.png][]

#### 3.5.2 开始挖矿 ####

#### ![1241225-20170921165353368-37896064.png][] ####

#### 3.5.3 停止挖矿 ####

把上述命令复制到终端，windows不太好用自己输入有问题。

![1241225-20170921165523681-487610444.png][]

#### 3.5.4 打开以太坊客户端 ####

![1241225-20170921165617196-288912627.png][]

看到这些跳动的数字了吧！这是你自己挖的矿。请关注以后的更新！

![1241225-20170921165722884-1558695427.png][]

#### 3.5.5 运行错误 ####

“Fatal: Error starting protocol stack: Access is denied.”

![1241225-20170921170022275-475038053.png][]

这错误是 因为你开启了2个进程， 这个时候你需要关闭 ethereum客户端 。
