truffle部署指定的合约

2021-10-02 09:06:42 作者：互联网

在truffle中部署指定的合约，可以根据文件的Index来区别，比如，/migrations目录下，有如下三个文件:
1_inital_migrations.js
2_deploy_HWT.js
3_deploy_SZT.js

部署第2个合约:2_deploy_HWT.js，使用命令：

migrate -f 2 --to 2

同理，部署第3个合约:2_deploy_SZT.js，使用命令：

migrate -f 3 --to 3

类推，部署第n个合约: n_deploy_XXX.js，使用命令：

migrate -f n --to n

1 进入指定的网段

1.1 公共配置

开启truffle-config.js里的助记词、私钥等配置。

const fs = require('fs');

const HDWalletProvider = require('@truffle/hdwallet-provider');
const infuraKey = fs.readFileSync(".infuraKey").toString().trim();
const mnemonic = fs.readFileSync(".mnemonic").toString().trim();

1.2 ropsten网段配置

在truffle-config.js的networks字段里，开启ropsten网段配置

    ropsten: {
      provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/` + infuraKey),
      network_id: 3,       // Ropsten's id
      gas: 5500000,        // Ropsten has a lower block limit than mainnet
      confirmations: 2,    // # of confs to wait between deployments. (default: 0)
      timeoutBlocks: 20000,  // # of blocks before a deployment times out  (minimum/default: 50)
      skipDryRun: true,     // Skip dry run before migrations? (default: false for public nets )
      port: 8545
    },

1.3 rinkeby网段配置

在truffle-config.js的networks字段里，开启rinkeby网段配置

    rinkeby: {
      provider: () => new HDWalletProvider(mnemonic, `https://rinkeby.infura.io/v3/` + infuraKey),
      network_id: 4,
    },

1.4 kovan网段配置

在truffle-config.js的networks字段里，开启kovan网段配置

    kovan: {
      provider: () => new HDWalletProvider(mnemonic, `https://kovan.infura.io/v3/` + infuraKey),
      network_id: 42,
    },

1.5 主网配置

在truffle-config.js的networks字段里，开启主网配置

    mainnet: {
      provider: () => new HDWalletProvider(mnemonic, `https://mainnet.infura.io/v3/` + infuraKey),
      network_id: 1,
    },

1.6 ganache配置

在truffle-config.js的networks字段里，添加一个ganache网段，用于本地测试

    ganache: {
      host: "127.0.0.1",     // Localhost (default: none)
      port: 8545,            // Standard Ethereum port (default: none)
      network_id: "*",       // Any network (default: none)
    },

truffle-config.js的完整配置如下：
//truffle-config.js

const fs = require('fs');

const HDWalletProvider = require('@truffle/hdwallet-provider');
const infuraKey = fs.readFileSync(".infuraKey").toString().trim();
const mnemonic = fs.readFileSync(".mnemonic").toString().trim();

module.exports = {
  networks: {
  
    ganache: {
      host: "127.0.0.1",     // Localhost (default: none)
      port: 8545,            // Standard Ethereum port (default: none)
      network_id: "*",       // Any network (default: none)
    },
    // development: {
    //   host: "127.0.0.1",     // Localhost (default: none)
    //   port: 8545,            // Standard Ethereum port (default: none)
    //   network_id: "*",       // Any network (default: none)
    // },
    // develop: {
    //   host: "127.0.0.1",     // Localhost (default: none)
    //   port: 8545,            // Standard Ethereum port (default: none)
    //   network_id: "*",       // Any network (default: none)
    //   gas: 8500000,           // Gas sent with each transaction (default: ~6700000)
    //   gasPrice: 20000000000,  // 20 gwei (in wei) (default: 100 gwei)
    // },

    // Another network with more advanced options...
    // advanced: {
    // port: 8777,             // Custom port
    // network_id: 1342,       // Custom network
    // gas: 8500000,           // Gas sent with each transaction (default: ~6700000)
    // gasPrice: 20000000000,  // 20 gwei (in wei) (default: 100 gwei)
    // from: <address>,        // Account to send txs from (default: accounts[0])
    // websockets: true        // Enable EventEmitter interface for web3 (default: false)
    // },

    // Useful for deploying to a public network.
    // NB: It's important to wrap the provider as a function.
    ropsten: {
      provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/` + infuraKey),
      network_id: 3,       // Ropsten's id
      gas: 5500000,        // Ropsten has a lower block limit than mainnet
      confirmations: 2,    // # of confs to wait between deployments. (default: 0)

    mainnet: {
      provider: () => new HDWalletProvider(mnemonic, `https://mainnet.infura.io/v3/` + infuraKey),

    // Useful for private networks
    // private: {
    // provider: () => new HDWalletProvider(mnemonic, `https://network.io`),
    // network_id: 2111,   // This network is yours, in the cloud.

    // }
  },

  // Set default mocha options here, use special reporters etc.
  mocha: {
    timeout: 300000,
