如何在新机器上设置github完成内容git push

如果你在一台新的机器上git pull 仓库，完成修改，然后git push，会发现下面错误：

bash 复制代码

Username for 'https://github.com': xiaomaolv
Password for 'https://xiaomaolvgithub.com': 
remote: Support for password authentication was removed on August 13, 2021.
remote: Please see https://docs.github.com/get-started/getting-started-with-git/about-remote-repositories#cloning-with-https-urls for information on currently recommended modes of authentication.
fatal: Authentication failed for 'https://github.com/xiaomaolv/'

这是因为你第一次在这台机器上操作，需要设置.

方案1 ssh

首先在本地机器生成ssh，如果已经有可以掠过：

bash 复制代码

 $ ssh-keygen -t rsa -C "xiaomaolv@xjblll-tech.comm"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/xiaomaolv/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/xiaomaolv/.ssh/id_rsa
Your public key has been saved in /home/xiaomaolv/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:onw16/MR30zP4u+dUmxKdnvtzLZ5jdU5iN4Qb4dIaj4 xiaomaolv@xjblll-tech.comm
The key's randomart image is:
+---[RSA 3072]----+
|                 |
|                 |
|                 |
|           o     |
|      . S + = = o|
|   . . o = * @ @o|
|    o . + o B XoB|
|     . ..E o =.=X|
|        .oo   oO@|
+----[SHA256]-----+

然后copy ssh-rsa 到github网页中的SSH and GPG keys中

bash 复制代码

cat /home/xiaomaolv/.ssh/id_rsa.pub 
ssh-rsa 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 xiaomaolv@xjblll-tech.comm

打开github网页，并添加：

本地执行测试

如果出现下面信息，则说明成功了。

bash 复制代码

$ ssh -T git@github.com
The authenticity of host 'github.com (20.205.243.166)' can't be established.
ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'github.com,20.205.243.166' (ECDSA) to the list of known hosts.
Hi ! You've successfully authenticated, but GitHub does not provide shell access

切换认证方式：

bash 复制代码

# 切换到 SSH
git remote set-url origin git@github.com:EnflameTechnology/FFmpeg-GCU.git

git push

bash 复制代码

$ git push

note: 如果在这个阶段还是出现permission not allowed ，那么就要去找github 仓库管理员要权限了。

http方式

除了上面提供的ssh方式，github还提供了第二种方式http方式

执行的命令如下，核心是如何获取TOKEN，

bash 复制代码

# 或切换到 PAT
git remote set-url origin https://<TOKEN>@github.com/EnflameTechnology/FFmpeg-GCU.git

其中是：

GitHub → Settings → Developer settings → Personal access tokens

TOKEN同时会发邮件到邮箱

总结：

两种方式git push
