生成SSH key命令,通常秘钥注释选择是邮箱

  1. ssh-keygen -t rsa -C "密钥的注释"

eg:

  1.  ssh-keygen -t rsa -C "baxiang"
  2. Generating public/private rsa key pair.
  3. Enter file in which to save the key (/Users/baxiang/.ssh/id_rsa):

默认会在相应路径下（/your_home_path）生成id_rsa和id_rsa.pub两个文件

  1. ls -ll ~/.ssh
  2. -rw-------  1 baxiang  staff  2590  6 21 22:57 id_rsa
  3. -rw-r--r--  1 baxiang  staff   561  6 21 22:57 id_rsa.pub

选择回车表示不设置密码

Created directory '/Users/baxiang/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/baxiang/.ssh/id_rsa.
Your public key has been saved in /Users/baxiang/.ssh/id_rsa.pub.
The key fingerprint is:
