github生成SSH公鑰

1 若是沒有安裝ssh，那麼使用下面的指令

sudo apt-get install ssh

2 檢查SSH公鑰

cd ~/.ssh

看看存不存在.ssh，若是存在的話，掠過下一步；不存在的請看下一步

3 生成SSH公鑰

$ ssh-keygen -t rsa -C "your_email@youremail.com" 

# Creates a new ssh key using the provided email Generating public/private rsa key pair. 

Enter file in which to save the key (/home/you/.ssh/id_rsa):

如今你能夠看到，在本身的目錄下，有一個.ssh目錄，說明成功了

3.1 輸入github密碼（留空按回車鍵）

Enter passphrase (empty for no passphrase): [Type a passphrase] 

Enter same passphrase again: [Type passphrase again]

這個時候輸入你在github上設置的密碼。

3.2 而後在.ssh中能夠看到

Your identification has been saved in /home/you/.ssh/id_rsa. 

# Your public key has been saved in /home/you/.ssh/id_rsa.pub.

# The key fingerprint is: 

# 01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db your_email@youremail.com

4 添加SSH公鑰到github

打開github，找到帳戶裏面添加SSH，把idrsa.pub內容複製到key裏面。

5 測試是否生效

使用下面的命令測試

ssh -T git@github.com

當你看到這些內容放入時候，直接yes

The authenticity of host 'github.com (207.97.227.239)' 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)?

看到這個內容放入時候，說明就成功了。

Hi username! 

You've successfully authenticated, but GitHub does not provide shell access.
