用于备忘一些问题的解决办法

• 一、WSL2代理问题
• 二、GitHub连接问题
  • 2.1 ssh认证失败问题
  • 2.2 kex_exchange_identification: Connection closed by remote host 问题
• 三、GitHub Action的小用处

一、WSL2代理问题

wsl2经常访问不了外网，难以下载一些文件，所以在本机有clash等代理方式的情况下，可以在zshrc中加入以下参数：

export hostip=$(cat /etc/resolv.conf |grep -oP '(?<=nameserver\ ).*')
export https_proxy="http://${hostip}:7890"
export http_proxy="http://${hostip}:7890"
export all_proxy = 'sock5://172.30.48.1:7890'
export ALL_PROXY = 'sock5://172.30.48.1:7890'

然后还需要在clash内打开allow lan

二、GitHub连接问题

2.1 ssh认证失败问题

1. 设置公私钥
2. 在zshrc内写入：

eval "$(ssh-agent)"
ssh-add ~/.ssh/github

2.2 kex_exchange_identification: Connection closed by remote host 问题

1. 经检查发现Github平台与本地的ssh key均配置正常
2. 执行命令ssh -T git@github.com返回上述结果
3. 原因：在锅锅的有效搜索方法下，发现可能是使用的梯子封禁了 Github 端口 22 的连接
4. 解决方案：为~/.ssh/config添加以下代码：

     Host github.com
      HostName ssh.github.com
      User git
      Port 443
   

三、GitHub Action的小用处

有时候有些jio本可能想让他定期执行，并给自己发送一些推送，但是为此开一个服务器比较浪费，所以可以用一手GitHub的action功能，实现定时/触发执行代码。

1. 在项目底下建立目录.github/workflows
2. 目录下建立xxx.yml文件
3. 编写触发条件及环境等，具体代码如下：

name: CI

# Controls when the workflow will run
on:
  # Triggers the workflow on push or pull request events but only for the master branch
  push:
    branches: [ python-dev ]
  pull_request:
    branches: [ python-dev ]
  schedule:
    - cron: '0 5 5,20 * *'
  # 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"
  get-proxy:
    # 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:
      - name: 'Checkout codes' # 步骤一，获取仓库代码
        uses: actions/checkout@v2
      # Runs a single command using the runners shell
      - name: Run a one-line script
        run: python3 ./jisujioben.py
