实践Substrate私有网络搭建

jasonruan 2020.07.22

1 前言

本文参考：https://substrate.dev/docs/en/tutorials/start-a-private-network/，搭建Substrate私有网络，并将其托管到telemetry.polkadot.io上。

2 搭建步骤

2.1 安装 Substrate Node Template 

# 安装依赖工具
$ curl https://getsubstrate.io -sSf | bash -s -- --fast

# clone最新分支版本的Substrate Node Template源码
$ git clone -b v2.0.0-rc4 --depth 1 https://github.com/substrate-developer-hub/substrate-node-template
$ cd substrate-node-template/
$ git checkout -b v2.0.0-rc4

# 初始化WebAssembly编译环境
source ~/.cargo/env
rustup update nightly
rustup update stable
rustup target add wasm32-unknown-unknown --toolchain nightly

# 编译
$ cargo build --release

2.2 创建Keys

使用Subkey命令，它是Substrate专用秘钥生成工具。安装方法：

$ cargo install --force subkey --git https://github.com/paritytech/substrate --tag v2.0.0-rc4

2.2.1 创建助记词

$ ./subkey --sr25519 generate
Secret phrase `text bubble owner rebuild damage today steel inflict mom book absent fiscal` is account:
  Network ID/version: substrate
  Secret seed:        0x29a4b095bb4ef2924cbc09f2c366cde44186de89348e8044b708527c35ae38dd
  Public key (hex):   0xec3ecd2ffebf75556c56e6cd183275a4017d70178d06c13d462a2245a902053a
  Account ID:         0xec3ecd2ffebf75556c56e6cd183275a4017d70178d06c13d462a2245a902053a
  SS58 Address:       5HQTpACjQHAE1o9niQctiFAzDLe4nKzMjjaW82ENTnS7DbGH

2.2.2 创建Key Pair 1

注：用于区块生成的Aura账号需要使用sr25519，用于区块确认（finalization）的GRANDPA账号需要使用ed25519。

$ ./subkey --sr25519 inspect "text bubble owner rebuild damage today steel inflict mom book absent fiscal//jasonruan//aura"

  SS58 Address:       5E9NB65gRVDMqNundHMFC3Umd4tdxocuWEcvAx31vj7hQPRW

2.3 创建用户自定义chain spec文件

2.3.1 创建chain spec文件

$ ./target/release/node-template build-spec --disable-default-bootnode --chain local > customSpec.json
2020-07-22 20:17:44 Building chain spec

2.3.2 修改chain spec文件

将customSpec.json文件中相关配置，改成前面创建的地址

  "name": "jsrzx Testnet",

        ]   
      },
      "balances": {
        "balances": [

      "sudo": {
        "key": "5GTz3X4NeranDE5ZUj6EzK2PiR6xFokevbKyNQ4REc57DREC"
      }

2.3.3 创建chain spec raw文件

$ ./target/release/node-template build-spec --chain=customSpec.json --raw --disable-default-bootnode > customSpecRaw.json
2020-07-22 20:23:48 Building chain spec

2.4 创建私有网络

2.4.1 启动Bootnode节点

2.4.1.1 执行启动命令

$ ./target/release/node-template   --ws-external --rpc-external --rpc-cors=all   --base-path /tmp/jsrzx-bootnode01   --chain=./customSpecRaw.json   --port 30333   --ws-port 9944   --rpc-port 9933   --telemetry-url 'ws://telemetry.polkadot.io:1024 0'   --validator   --rpc-methods=Unsafe   --name jsrzx-BootNode01
2020-07-22 22:04:20 It isn't safe to expose RPC publicly without a proxy server that filters available set of RPC methods.

启动后，我们并未看到有区块产生，还需要执行下面的操作。

接下来我们需要把我们创建的keys添加到该节点的keystore里面，这步操作在后续每个网络节点部署时都必不可少。

2.4.1.2 添加keys到keystore

方式一：使用Polkadot-JS Apps UI
image.png
方式二：使用curl命令
  • 添加aura1
curl http://localhost:9933 -H "Content-Type:application/json;charset=utf-8" -d "@aura1.json"
{"jsonrpc":"2.0","result":null,"id":1}

{
  "jsonrpc":"2.0",
  "id":1,
  "method":"author_insertKey",
  "params": [
    "aura",
    "text bubble owner rebuild damage today steel inflict mom book absent fiscal//jasonruan//aura",
    "0xc2b21193cf6669c82421036e382a945b45db9b0c24dff201cd341346bbe80d61"
  ]
}
  • 添加grandpa1
curl http://localhost:9933 -H "Content-Type:application/json;charset=utf-8" -d "@gran1.json"
{"jsonrpc":"2.0","result":null,"id":1}

{
  "jsonrpc":"2.0",
  "id":1,
  "method":"author_insertKey",
  "params": [
    "gran",
    "text bubble owner rebuild damage today steel inflict mom book absent fiscal//jasonruan//grandpa",
    "0x5c066fdf0bfc266fdef4153371c07673108b4681005bfddb02b86612ee362866"
  ]
}

2.4.2 添加验证人节点

2.4.2.1 执行启动命令

$   ./target/release/node-template   --base-path /tmp/jsrzx-validator01  --chain ./customSpecRaw.json   --port 30334   --ws-port 9945   --rpc-port 9934   --telemetry-url 'ws://telemetry.polkadot.io:1024 0'   --validator   --rpc-methods=Unsafe   --name jsrzx-Validator01   --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWC2mv6TUKbQbgujE57BWXtPdZM45E1tXtr8ekpUFwZoMX

我们可以看到连接已经建立，不断有best区块产生，但是没有finalized区块产生，这时需要我们在验证人节点也添加keys，并且重启节点。
