2. 配置用户名和邮箱
git config --global user.name "username"
git config --global user.email "your_email@example"
这里global是配置全局用户名和邮箱，去掉–global参数，可以为当前目录的仓库单独配置用户名和邮箱。
完了可以使用下面的命令查看配置
git config --get user.name
3. 配置SSH
-
3.1 生成SSH密钥
$ ssh-keygen -t ed25519 -C "your_email@example"这将使用提供的电子邮件作为标签创建一个新的 SSH 密钥。
ed25519是一种密码算法。
Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): github Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in github. Your public key has been saved in github.pub. The key fingerprint is: SHA256:sxxxxxxxxxxxxxxxxxxxxxxx xxx@xxx The key's randomart image is: +---[RSA 3072]----+ | ....o ..=| | ..+ = B+| | o . = X *| | + o = * | | . S + . .| | . + + o | | . + o o... | | B . .o.E| | +.+. o+*+| +----[SHA256]-----+运行后依次需要输入密钥文件名、密钥密码和确认密码。可以直接enter，使用默认的。
我这边是给出了文件名. -
3.2 将SSH密钥添加到ssh-agent
eval "$(ssh-agent -s)" $ ssh-add ~/.ssh/githubIdentity added: /root/.ssh/github (xxxxx@xxx)将github替换为你的密钥名。
如果不进行这一步，直接跳到下面第三步，将不能使用ssh访问github。
ssh -T git@github The authenticity of host 'github (20.205.243.166)' can't be established. ECDSA key fingerprint is SHA256:pxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Are you sure you want to continue connecting (yes/no/[fingerprint])? Y Please type 'yes', 'no' or the fingerprint: yes Warning: Permanently added 'github,20.205.243.166' (ECDSA) to the list of known hosts. git@github: Permission denied (publickey).访问被拒绝。
-
3.3 复制公钥，打开 github - setting - 左侧 SSH and GPG keys - new SSH key
测试访问
ssh -T git@github Hi xxxx! You've successfully authenticated, but GitHub does not provide shell access.
4. 使用SSL方式克隆仓库到本地
git clone git@github:user/repo.git
