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

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”

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

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
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”,

]
}
2.4.2 添加验证人节点
2.4.2.1 执行启动命令

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。
2.4.2.2 添加keys到keystore
方式一：使用Polkadot-JS Apps UI
方式二：使用 curl 命令
· 添加 aura2
curl http://localhost:9934 -H “Content-Type:application/json;charset=utf-8” -d “@aura2.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//rzexin//aura”,
“0x9c3c7edccb0c653c6a867ed9b51cf8a21265a6099109f8bbc03517df65ad7c71”
]
}
· 添加 grandpa2
curl http://localhost:9934 -H “Content-Type:application/json;charset=utf-8” -d “@gran2.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//rzexin//grandpa”,
“0x9d1811c2cc677a55b04eac77a4390b64a1760e93cfe5577500c89cc921372aec”
]
}
2.4.3 重启节点
之所以没有**finalized**区块产生，是因Substrate节点在导入grandpa key后，需要进行重启。
重启之后看到成功产生 finalized 区块。
