CentOS 7 生成SSH连接GitHub的SSH-key

  1. 生成秘钥
    //换成你自己的邮箱
    ssh-keygen -t rsa -C "343672271@qq.com"
    //一直next并记住生成的地址
    Generating public/private rsa key pair.
    Enter file in which to save the key (/root/.ssh/id_rsa):
    Created directory '/root/.ssh'.
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in /root/.ssh/id_rsa.
    Your public key has been saved in /root/.ssh/id_rsa.pub.
  2. 进入.ssh 目录提出key
    [root@localhost ~]# cd .ssh
    [root@localhost .ssh]# ls
    id_rsa  id_rsa.pub
    //把显示的内容复制到GitHub的SSHkey配置即可
    [root@localhost .ssh]# cat id_rsa.pub
  3. 测试
    [root@localhost .ssh]# ssh -T git@github.com
    The authenticity of host 'github.com (192.30.255.113)' can't be established.
    RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
    Are you sure you want to continue connecting (yes/no)? y
    Please type 'yes' or 'no': yes
    Warning: Permanently added 'github.com,192.30.255.113' (RSA) to the list of known hosts.
    Hi megoc! You've successfully authenticated,but GitHub does not provide shell access.
