1. 安装 sh-copy-id
sudo curl -L https://raw.githubusercontent.com/beautifulcode/ssh-copy-id-for-OSX/master/install.sh | sh
或者
brew install ssh-copy-id
2. 生成登录公钥私钥对
$ ssh-keygen -o -t rsa -C "1zoxun1@gmail.com" -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/zongxun/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/zongxun/.ssh/id_rsa
Your public key has been saved in /Users/zongxun/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:ewAVKPAGTO/lI+lE2VwUDThKV2xoSY8JINGqTGDleMY 1zoxun1@gmail.com
The key's randomart image is:
+---[RSA 4096]----+
