ubuntu如何获取sshkey

ubuntu获取sshkey的方法：

打开终端命令行。

输入以下命令。

ssh-keygen -t rsa -C "your_email@example.com" //your_email@example.com为你在GitHub或者gitLab注册时的邮箱

执行后，终端会显示如下结果，按回车保存。

Created directory '/Users/xxx/.ssh'.
Enter passphrase (empty for no passphrase):

提示设置 passphrase，设置成功后会显示：

Your identification has been saved in /Users/xxx/.ssh/id_rsa.
Your public key has been saved in /Users/xxx/.ssh/id_rsa.pub.
The key fingerprint is:
ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48 your_email@example.com
The key's randomart image is:
心形图形

接着在终端输入以下命令：

ssh-add ~/.ssh/id_rsa

按要求填刚刚设置的passphrase，成功后会显示：

Identity added: /Users/xxx/.ssh/id_rsa (/Users/xxx/.ssh/id_rsa)

最后再输入以下命令就可以获取你的sshkey了，命令如下：

cat /Users/xxx/.ssh/id_rsa.pub
