Git 配置SSH公钥

检查电脑上是否已经有SSH的Key

cd ~/.ssh

若出现下方提示直接创建新的Key

-bash: cd: /Users/singularity/.ssh: No such file or directory

ls -al ~/.ssh 

创建新的Key

ssh-keygen -t rsa -C "邮箱地址"

出现下方提示即为成功，默认回车即可

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/singularity/.ssh/id_rsa):

设置Key密码

Enter passphrase (empty for no passphrase):
Enter same passphrase again:

添加Key至ssh-agent

eval "$(ssh-agent -s)"

*添加Key至rsa，并输入密码

ssh-add ~/.ssh/id_rsa

查看ssh公钥

cd ~/.ssh 

cat id_rsa.pub

复制公钥至剪切板

pbcopy <id_rsa.pub 

最后将剪切板中的公钥粘贴值GitLab或者GitHub中即可

个人设置中找到key页面粘贴即可

更换秘钥或配置无密码

ssh-keygen -p

重新配置路径

Enter file in which the key is (/Users/singularity/.ssh/id_rsa): 

将括号内的路径复制出去即可，之后输入旧密码后一直回车确认即可设置为无密码，避免每次要输入密码才可使用

更新Git账号及密码

git config --global credential.helper osxkeychain

并在钥匙串中删除互联网密码github.com项，提交时重新输入账号密码即可
