GitHub Clone and Push

在Github创建私有仓库“blog”

*登陆Github后，直接点New repository来创建一个新的私有仓库，比如：我创建了一个blog的仓库。

clone代码到本地电脑

在本地电脑，打开Git命令行，进入希望放置blog的目录，运行“git clone git@github.com:zhenzhang20/blog.git” 来clone代码到本地。其中clone的地址可以在仓库中看到：

• 过程中可能遇到报错：

zz@Zhen MINGW64 /d/develop/www
$ git clone git@github.com:zhenzhang20/blog.git
Cloning into 'blog'...
ssh: connect to host github.com port 22: Connection refused
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

• 遇到22端口报错，可能是网络原因，先运行“ssh -T -p 22 git@ssh.github.com”检查22端口是否可以使用（默认是22端口，则可以使用“ssh -T git@github.com”）：

  $ ssh -T git@github.com
  ssh: connect to host github.com port 22: Connection refused
  

• 如果22端口报“Connection refused”，则可以尝试修改使用433端口，依旧先检查433端口是否可以使用，运行“ ssh -T -p 443 git@ssh.github.com” 检查433端口是否可用：

  zz@Zhen MINGW64 /
  $ ssh -T -p 443 git@ssh.github.com
  The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
  ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
  This host key is known by the following other names/addresses:
    ~/.ssh/known_hosts:1: github.com
  Are you sure you want to continue connecting (yes/no/[fingerprint])?

• 若433端口可用，则在.ssh 目录创建文件：config，并编辑：~/.ssh/config, 文件内容为：

  Host github.com
  Hostname ssh.github.com
   Port 443

• 遇到“Failed to connect to ** after 2243 ms: Couldn’t connect to server”报错一般为网络问题，需要检查是否能正常访问Github：

  zz@Zhen MINGW64 /d/develop/www
  $ git clone <https://github.com/zhenzhang20/blog.git>
  Cloning into 'blog'...
  fatal: unable to access '<https://github.com/zhenzhang20/blog.git/>': Failed to connect to github.com port 443 after 2243 ms: Couldn't connect to server

• 再次运行“ssh -T git@github.com” 检查是否可以连接成功。显示内容包括“You’ve successfully authenticated”则表示成功。

  zz@Zhen MINGW64 /
  $ ssh -T git@github.com
  The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
  ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
  This host key is known by the following other names/addresses:
    ~/.ssh/known_hosts:1: github.com
  Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
  Warning: Permanently added '[ssh.github.com]:443' (ED25519) to the list of known hosts.
  Hi zhenzhang20! You've successfully authenticated, but GitHub does not provide shell access.

  

• 可以成功连接后，进行clone代码到本地：

  zz@Zhen MINGW64 /d/develop/www
  $ git clone git@github.com:zhenzhang20/blog.git
  Cloning into 'blog'...
  remote: Enumerating objects: 8, done.
  remote: Counting objects: 100% (8/8), done.
  remote: Compressing objects: 100% (4/4), done.

  Receiving objects: 100% (8/8), done.

在下载的blog目录中添加一个“add.md”文件，并尝试提交到Github仓库

• 进入blog目录，会自动显示当前仓库的branch为main

• 添加新增的文件、增加提交注释、提交到远程仓库

  git add .
  git commit -m 'initial'
  git push origin main

  

• 过程中可能报错：

  git push origin main
  fatal: unable to access 'https://github.com.zhenzhang20/blog.git/': Recv failure: Connection was reset

• 解决方法,运行：

  git config --global --unset http.proxy
  git config --global --unset https.proxy
