github actions 自动部署 hexo 博客到 github 库

前提已创建两个仓库：

私有仓库 - 存储博客源代码
公共仓库 - 存储生成后的博客静态文件

首先设置ssh 密钥对

　　1.生成密钥可以使用git bash 命令工具,执行下面的命令，生成私钥和公钥

ssh-keygen -t rsa -C '邮箱'

　　2.设置github

在github 账户中设置公钥，路径：SSH and GPG keys (github.com) ，SSH keys 点击 new ssh key

打开公钥文件，复制内容到 key 输入框
打开私有库 settings-》secrets，设置私有密钥，点击 New repository secret；打开私钥文件，将私钥内部复制进key输入框中。
设置actions，打开私有库的 actions ，点击 set up a workflow yourself.
编写配置文件

# This is a basic workflow to help you get started with Actions

name: clrs-blog

# Controls when the action will run. 
on:
  # Triggers the workflow on push or pull request events but only for the main2021 branch
  push:
    branches: [ main2021 ]

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v2
        with: 
          node-version: '>=12.x'

      # Runs a set of commands using the runners shell
      - name: Install hexo-cli
        run: |
         npm install hexo-cli -g
         npm install
         
      - name: Config Private Key
        env:
         PRIVATE_KEY: ${{ secrets.PRIVATE_KEY }} #此处的PRIVATE_KEY 是配置私有库时settings-》secrets的名称
        run: |
         mkdir -p ~/.ssh/
         echo "$PRIVATE_KEY" > ~/.ssh/github_rsa 
         chmod 600 ~/.ssh/github_rsa
         ssh-keyscan github.com >> ~/.ssh/known_hosts
      - name: Config Git
        run: | 
         git config --global user.name 'xxx' 
         git config --global user.email 'xxx@xx.x'
      - name: Deploy
        run: |
         hexo clean & hexo g & hexo d

　　3.设置hexo 配置文件

　　　在_config.yml中找到deploy节点，配置如下

deploy:
  type: git
  repo: git@github.com:xxxxx/xxxxx.github.io.git #github库 ssh 地址,此处一定要复制 ssh地址，如果用https地址，actions 运行的时候，执行到hexo deploy 会报错 could not read Username for 'https://github.com': No such device or address
  branch: main2021
  name: xxxx
  email: xxxx@xx.x

　　最后，做好以上配置，即可写新文章然后推送到github，actions 将自动运行并将生成的静态文件部署到公开库中。
