一，搭建单节点链
- 搭建substrate基本运行环境
- 编译成功
- 单节点运行能够出块。
substrate的官方安装脚本掩盖了很多细节，在初次使用可以体验，但是以后安装建议直接安装，具体可以参考脚本https://getsubstrate.io/index.html，包括ubuntu安装的依赖包安装以及rust&cargo安装的环境变量等设置。具体步骤如下：
- 基本环境安装：Ubuntu 18.04.3 LTS
- 依赖安装apt install -y cmake pkg-config libssl-dev git gcc build-essential git clang libclang-dev
- 安装
rustcurl https://sh.rustup.rs -sSf | sh -s -- -y
source ~/.cargo/env
rustup default stable
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly - 下载并编译substrate
从git下载substate源码：
git clone https://github.com/paritytech/substrate
cd substrate
WASM_BUILD_TYPE=release cargo build - 运行单节点
cargo run --bin substrate -- --dev -d .sub --execution=NativeElseWasm
有以下输出：

二，测试单节点链
- 下载前端源码
git clone https://github.com/substrate-developer-hub/substrate-front-end-template.git - 安装yarn
安装 sudo apt install curl
添加GPG key
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
添加源
sudo sh -c 'echo "deb https://dl.yarnpkg.com/debian/ stable main" >> /etc/apt/sources.list.d/yarn.list'sudo apt update
sudo apt install yarn
3.编译运行
cd substrate-front-end-template
yarn build
yarn start
