Git-SSH配置

Git-SSH配置(来自个人早期的OneNote笔记，目前已经迁移到语雀)；语雀查看链接

Git 连接（可创建一个 Key 同时使用GitEE、GitHub、GitLab等）

创建 SSH key

将邮件地址替换为你 Gitee 或者 Github 使用的邮件地址（GitHub 和 GitEE 的邮箱地址相同也没事）

**ssh-keygen -t rsa -C "xxx@xxx.com"

进入到 .ssh 路径下：

• Windows： **~/.ssh （即为路径：C:\Users\你电脑用户名\.ssh）
• Linux： ** ${HOME}/.ssh

# Window系统为 
cd ~/.ssh
# Linux 系统则为
cd ${HOME}/.ssh

# 进到用户家的目录下的 .ssh 路径下
$ ~/.ssh
ssh-keygen -t rsa -C "chxlay@gmail.com"

这一步如果默认回车，会生成名为 id_rsa 的文件，你可以输入不同的名字来便于识别文件，比如生成 Gitee 的 ssh key 可以设置为 id_rsa_gitee，设置 Github 的 ssh key 可以设置为 id_rsa_github ，我这里设置为 id_rsa_github，你也可以直接命名为 id_rsa_git 同时使用到 github、gitee、gitlab 共用了。

这里重命名是非必须的，你也可以直接回车使用默认的key 命名，然后一路回车

成功生成SSH秘钥文件

添加 Key到Git

将以上创建的 public key 添加到 Git 中，找到用户目录下的 .ssh 文件夹，查看并复制创建好的 id_rsa_gitee.pub 或 id_rsa_github.pub 的内容。

可以直接编辑器打开或者命令查看 cat id_rsa_github.pub

$ cat id_rsa_github.pub
ssh-rsa

配置Git SSH Keys

• GitHub

• GitEE

添加配置文件

内容如下：

gitlab.yourdomain.com 更换为你自己的gitlab域名

# gitee码云
Host gitee.com
HostName gitee.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_git
IdentitiesOnly yes
 
#  GitHub
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_git
IdentitiesOnly yes

#  GitLab
Host gitlab.yourdomain.com
HostName gitlab.yourdomain.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_git
IdentitiesOnly yes

连接测试

• GitHub

ssh -T git@github.com

The authenticity of host 'github.com (13.229.188.59)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'github.com,13.229.188.59' (RSA) to the list of known hosts.
Hi chxlay! You've successfully authenticated, but GitHub does not provide shell access.

• GItEE

ssh -T git@gitee.com

Warning: Permanently added 'gitee.com,180.97.125.228' (ECDSA) to the list of known hosts.
Hi chxlay! You've successfully authenticated, but GITEE.COM does not provide shell access.

• GitLab

gitlab.yourdomain.com 更换为你自己的gitlab域名

ssh -T git@gitlab.yourdomain.com
