ubuntu 如何生成秘钥 (ssh key)

1:首先在终端输入

ssh-keygen -t rsa -C "your_email@example.com"

2:

之后一路回车键(Enter)，就生成了；

Generating public/private rsa key pair.
Enter file in which to save the key (/home/your_email/.ssh/id_rsa): 
Created directory '/home/your_email/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 

Your identification has been saved in /home/your_email/.ssh/id_rsa.
Your public key has been saved in /home/your_email/.ssh/id_rsa.pub.
The key fingerprint is:

85:60:59:1a:77:45:22:b5:56:c1:10:4e:1f:9f:6f:c8 your_email@example.com
The key's randomart image is:

最后生成的秘钥在/home/use/生成一个隐藏文件.ssh，打开隐藏文件，两个文件id_rsa 和 id_rsa.pub,
id_rsa.pub是你的公钥，拷贝这两个
