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 "[email protected]"
   //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 [email protected]
   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.
