- 用 Mac 自带工具，生成 ssh Key
命令行：ssh-keygen -t rsa -C xxxx@github.com
rsa 加密算法
-C 创建账号
ssh-keygen -t rsa -C xxxx@qq.com
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/temp/.ssh/id_rsa): /Users/temp/.ssh/id_rsa_xiaobu
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/temp/.ssh/id_rsa_temp.
Your public key has been saved in /Users/temp/.ssh/id_rsa_temp.pub.
The key fingerprint is:
SHA256:9apFioweHNwSwFnL/GKYBlZxJrnbuzumFh3YZK09xII xxxx@github.com
The key's randomart image is:
+---[RSA 3072]----+

- 打开.ssh 文件中 pub 文件复制，访问https://github.com/settings/keys 点击添加 New SSH keys,把复制内容填充到下图中

名称自定义 ，点击 Add SSH key 即可 - 将 ssh 密钥添加到 ssh-agent中
ssh-add ~/.ssh/id_rsa_temp
- 测试：ssh -T git@github.com
Hi xxxx(名称)! You've successfully authenticated, but GitHub does not provide shell access.
- 配置 config 进入 Mac 根目录的.ssh 文件中 打开 config
#个人账号
Host person.github.com
HostName github.com
User person_用户名
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_person
#公司账号
Host company.github.com
HostName github.com
User company_用户名
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_company
6.替换项目仓库地址
- 查看当前项目的远程地址
git remote -v
origin https://github.com/xxxx.git (fetch)
origin https://github.com/xxxx.git (push)
- 移除当前项目的远程地址
git remote remove origin
- 添加当前项目的远程地址
git remote add origin git@company.github.com:xxxx.git
地址中 company.github.com 对应的是 config 文件中 host 后面内容
注意：
- 如果发现项目不能提交时：
Warning: Permanently added the RSA host key for IP address '52.74.223.119' to the list of known hosts.
git@github.com: Permission denied (publickey)
执行 ： ssh-add ~/.ssh/id_rsa_temp
- 出现 "The current branch master has no upstream branch "
问题原因：本地分支没有和远程分支关联起来
解决方案：git push --set-upstream origin master (master代表远程分支名称)
