## 1. 摘要

通过 [技术小白如何开发一个DAPP区块链应用(以宠物商店为例)](https://www.jianshu.com/p/9844d97ef1d0) 学习，大家掌握了一个DAPP的编程和以太坊私有测试环境调试，本文做进一步的技术深入学习。
**【本文目标】**
（1）采用INFURA配置的方式把智能合约部署到ROPSTEN测试网络；
（2）采用INFURA配置的方式把智能合约部署到以太坊主网络；
（3）了解采用.env配置的方式把助记词保存到本地防止泄露；

**【前提条件】**
本文假设你已完成 [《第六课 技术小白如何开发一个DAPP区块链应用(以宠物商店为例)》](https://www.jianshu.com/p/9844d97ef1d0) 的学习，在UBUTU环境编译成功智能合约，通过浏览器运行宠物商店程序并点击领养宠物成功。

## 2. 操作内容

### 2.1 注册infura获取API-KEY

**地址** ： [https://infura.io](https://infura.io)

![](https://img.learnblockchain.cn/2020/02/01_/737903465.png)

辉哥注册后，获得API KEY：8ce5ebd357144bef8dceae3de1915e29

### 2.2 增加配置文件.env

Dotenv是一个零依赖模块，用于从".env"文件中导入环境变量到 [process.env](https://nodejs.org/docs/latest/api/process.html#process_process_env) 。对DAPP来说，这样就可以不用上传钱包助记词等核心机密到GITHUB，便于资产安全。

**如何获取META MASK的助记词**
META MASK的助记词是针对原创账户的。在TRUFFLE框架下默认使用第一个创建的ACCOUNT1进行部署操作。

![](https://img.learnblockchain.cn/2020/02/01_/107402287.png)

2.获取seed KEY

**如何获取imToken钱包的助记词**
imToken钱包的助记词一般在你创建钱包的时候已经备份好了，之后会被删除。钱包此时只能导出私钥或者keystore了。

### 2.3 增加配置文件truffle.js的ROSPTEN和MAINNET环境配置

修改配置文件配置文件truffle.js，增加ROSPTEN和MAINNET环境配置内容。

```
/*读取.env环境配置的文件变量定义*/
const dotenv = require('dotenv');
const result = dotenv.config();
if (result.error) {
  throw result.error;
}
console.log(result.parsed);

var NonceTrackerSubprovider = require("web3-provider-engine/subproviders/nonce-tracker");
var HDWalletProvider = require("truffle-hdwallet-provider");

/*访问https://infura.io/注册后获取的api-key*/
var infura_apikey = "8ce5ebd357144bef8dceae3de1915e29";

/*读取.env文件配置的助记词*/
var mnemonic_ropsten = process.env.mnemonic_ropsten;
var mnemonic_mainnet = process.env.mnemonic_mainnet;

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*", // Match any network id
      gas: 4500000
    },
    local: {
      host: "127.0.0.1",
      port: 8545,
      network_id: "*", // Match any network id
      //gas: 4300000
    },
    ropsten: {
      provider: new HDWalletProvider(mnemonic_ropsten, "https://ropsten.infura.io/"+infura_apikey),
      network_id: 3,
      gas: 3012388,
      gasPrice: 30000000000
    },
    mainnet: {
      provider: function () {
        var wallet = new HDWalletProvider(mnemonic_mainnet, "https://mainnet.infura.io/Np7IGWoN2UOb0tgRWx55");
        var nonceTracker = new NonceTrackerSubprovider();
        wallet.engine._providers.unshift(nonceTracker);
        nonceTracker.setEngine(wallet.engine);
        return wallet;
      },
      gas: 6000000,
      network_id: 1,
      gasPrice: 10 * 1000000000
    }
  }
};

```

### 2.5 安装 truffle-hdwallet-provider

Infura组织是MetaMask背后的以太坊供应商。Infura提供了一个托管的以太坊节点集群，可以将你开发的以太坊智能合约部署到infura提供的节点上，而无需搭建自己的以太坊节点。
Infura不保存你的私钥，Infura可以通过使用HDWalletProvider来签署交易。 该服务可以处理事务签名以及与以太坊网络的连接。
在宠物商店根目录下运行命令：

```
npm install truffle-hdwallet-provider

```

成功输出参考如下：

```
duncanwang@ubuntu:~/work/dapp-guide-pet-shop$ npm install truffle-hdwallet-provider

+ truffle-hdwallet-provider@0.0.6
added 566 packages from 381 contributors in 188.892s

```

辉哥在安装truffle-hdwallet-provider时遇到了巨大的各种坑。刚开始怀疑是被墙的问题，尝试过各种手段，最终发现是没有安装C/C++编译器的欢迎，参考本文章节"3，常见问题和解决方法"解决。

### 2.6 安装 dotenv

```
npm install  dotenv

```

安装成功的输入如下：

```
duncanwang@ubuntu:~/work/dapp-guide-pet-shop$ npm install  dotenv
npm WARN truffle-hdwallet-provider@0.0.6 requires a peer of truffle@4.x but none is installed. You must install peer dependencies yourself.

+ dotenv@6.0.0
added 1 package from 1 contributor in 15.671s

```

如果安装失败，请参考本文章节"3，常见问题和解决方法"解决。

### 2.7 把智能合约部署到ROPSTEN测试网络

(1), 在宠物商店根目录下运行命令：

```
truffle migrate --network ropsten  --reset --compile-all

```

重新编译成功后会部署到ropsetn测试环境。成功输出内容参考：

```
duncanwang@ubuntu:~/work/dapp-guide-pet-shop$ truffle migrate --network ROPSTEN  --reset --compile-all

(2) 本次因为不需要采用本地环境，所以不需要启动ganache-cli环境，但是需要在独立环境窗口安装，运行lite-server环境，以便访问宠物商店网页。
输入命令：

```
npm install lite-server --save-dev
npm run dev

```

安装成功输出参考：

```
duncanwang@ubuntu:~/work/dapp-guide-pet-shop$ npm install lite-server --save-dev
npm WARN truffle-hdwallet-provider@0.0.6 requires a peer of truffle@4.x but none is installed. You must install peer dependencies yourself.

## 3，常见问题和解决方法

### 3.1 安装truffle-hdwallet-provider失败

**【输出描述】**

```
Error: Error: Command failed: ./configure
configure: error: in `/home/duncanwang/work/cet-token/node_modules/scrypt/scrypt/scrypt-1.2.0':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
...

```

**【解决方法】**
针对这个问题的解决，辉哥走过较多的弯路，包括VPN，安装GCC"npm install -g gcc", "npm rebuild"都没有解决。最终通过运行命令解决了。

```
sudo apt-get install build-essential

```

**【解决方法2】**
辉哥在CentOS6.5上安装truffle-hdwallet-provider时又遇到类似问题。采用CentOS的安装命令
`yum groupinstall "Development Tools" yum install -y gcc g++ kernel-devel`
安装成功后编译truffle-hdwallet-provider时还是失败。
查看g++的版本，发现是V4.4.7的，这个至少需要V4.7才能成功。

```
#g++ --version
g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23)
Copyright (C) 2010 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

```

最后参考 [《CentOS升级gcc4.4.7到gcc4.8.5》](https://blog.csdn.net/shine_journey/article/details/62039381) 文档，花了1个多小时完成g++的版本升级后，安装truffle-hdwallet-provider才成功。

### 3.2 部署到主网不成功

**【输出描述】**

```
Running migration: 1_initial_migration.js
  Deploying Migrations...
Error encountered, bailing. Network state unknown. Review successful transactions manually.
insufficient funds for gas * price + value

```

**【解决方法】**
（1）辉哥忘记在.env中配置mnemonic_mainnet的助记词，提示也是这个。
（2）后来辉哥使用METAMASK导出的助记词配置给mnemonic_mainnet，也往METAMASK导入了有足够主网ETH的账号，还是提示错误。后来确认导入账号的助记词不能从METAMASK导出。获取正确的助记词就解决了。

### 3.3 安装TRUFFEL5.0版本后，部署到ROPSTEN网络失败

**【输出描述】**

```
duncanwang@ubuntu:~/work/PuzzleBID$ truffle migrate --network ropsten  --reset
...
Error: Cannot find module 'web3-provider-engine/subproviders/nonce-tracker'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:548:15)

```

**【解决方法】**
安装这2步之后，部署到ROPSTEN就成功了。

```
duncanwang@ubuntu:~/work/PuzzleBID$ sudo npm install  web3-provider-engine

duncanwang@ubuntu:~/work/PuzzleBID$ sudo node-gyp rebuild

```

2.8 把智能合约部署到以太坊主网络

记得把有以太坊余额的助记词配置到.env文件。运行命令：

truffle migrate --network mainnet  --reset --compile-all

运行成功结果参考：

duncanwang@ubuntu:~/work/dapp-guide-pet-shop$truffle migrate --network mainnet --reset --compile-all
...
Writing artifacts to ./build/contracts

3，常见问题和解决方法

3.1 安装truffle-hdwallet-provider失败

【输出描述】

Error: Error: Command failed: ./configure
configure: error: in `/home/duncanwang/work/cet-token/node_modules/scrypt/scrypt/scrypt-1.2.0':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
...

【解决方法】 针对这个问题的解决，辉哥走过较多的弯路，包括VPN，安装GCC"npm install -g gcc", "npm rebuild"都没有解决。最终通过运行命令解决了。

sudo apt-get install build-essential

【解决方法2】 辉哥在CentOS6.5上安装truffle-hdwallet-provider时又遇到类似问题。采用CentOS的安装命令 yum groupinstall "Development Tools" yum install -y gcc g++ kernel-devel 安装成功后编译truffle-hdwallet-provider时还是失败。查看g++的版本，发现是V4.4.7的，这个至少需要V4.7才能成功。

#g++ --version
g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23)
Copyright (C) 2010 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

最后参考《CentOS升级gcc4.4.7到gcc4.8.5》文档，花了1个多小时完成g++的版本升级后，安装truffle-hdwallet-provider才成功。

3.2 部署到主网不成功

【输出描述】

Running migration: 1_initial_migration.js
  Deploying Migrations...
Error encountered, bailing. Network state unknown. Review successful transactions manually.
insufficient funds for gas * price + value

【解决方法】 （1）辉哥忘记在.env中配置mnemonic_mainnet的助记词，提示也是这个。（2）后来辉哥使用METAMASK导出的助记词配置给mnemonic_mainnet，也往METAMASK导入了有足够主网ETH的账号，还是提示错误。后来确认导入账号的助记词不能从METAMASK导出。获取正确的助记词就解决了。

3.3 安装TRUFFEL5.0版本后，部署到ROPSTEN网络失败

【输出描述】

duncanwang@ubuntu:~/work/PuzzleBID$ truffle migrate --network ropsten  --reset
...
Error: Cannot find module 'web3-provider-engine/subproviders/nonce-tracker'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:548:15)

【解决方法】 安装这2步之后，部署到ROPSTEN就成功了。

duncanwang@ubuntu:~/work/PuzzleBID$ sudo npm install  web3-provider-engine

duncanwang@ubuntu:~/work/PuzzleBID$ sudo node-gyp rebuild
