如何生成SSH key

SSH key提供了一种与GitHub通讯的方式,经过这种方式,可以在不输入密码的状况下,将GitHub做为本身的remote端服务器,进行版本控制前端

步骤

  • 检查SSH keys是否存在
  • 生成新的ssh key
  • ssh key添加到GitHub中

1. 检查SSH keys是否存在

输入下面的命令,若是有文件id_rsa.pubid_dsa.pub,则直接进入步骤3将SSH key添加到GitHub中,不然进入第二步生成SSH keygit

ls -al ~/.ssh
复制代码

以下图就表示存在,能够直接跳入第三步:github

2. 生成新的ssh key

  1. 第一步:生成public/private rsa key pair 在命令行中输入ssh-keygen -t rsa -C "your_email@example.com"

默认会在相应路径下(/your_home_path)生成id_rsaid_rsa.pub两个文件,以下面代码所示web

ssh-keygen -t rsa -C "your_email@example.com"
# Creates a new ssh key using the provided email
Generating public/private rsa key pair.
Enter file in which to save the key (/your_home_path/.ssh/id_rsa):
复制代码
  1. 第二步:输入passphrase(本步骤能够跳过)

设置passphrase后,进行版本控制时,每次与GitHub通讯都会要求输入passphrase,以免某些“失误”segmentfault

Enter passphrase (empty for no passphrase): [Type a passphrase]
Enter same passphrase again: [Type passphrase again]
复制代码

sample result:bash

Your identification has been saved in /your_home_path/.ssh/id_rsa.
Your public key has been saved in /your_home_path/.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@example.com
复制代码
  1. 第三步:将新生成的key添加到ssh-agent中:
# start the ssh-agent in the background
eval "$(ssh-agent -s)"
Agent pid 59566
ssh-add ~/.ssh/id_rsa
复制代码

3.将ssh key添加到GitHub中

用本身喜欢的文本编辑器打开id_rsa.pub文件,里面的信息即为SSH key,将这些信息复制到GitHub的Add SSH key页面便可服务器

不一样的操做系统,均有一些命令,直接将SSH key从文件拷贝到粘贴板中,以下:ssh

  • Mac
pbcopy < ~/.ssh/id_rsa.pub
# Copies the contents of the id_rsa.pub file to your clipboard
复制代码
  • Windows
clip < ~/.ssh/id_rsa.pub
# Copies the contents of the id_rsa.pub file to your clipboard
复制代码
  • Linux
sudo apt-get install xclip
# Downloads and installs xclip. If you don't have `apt-get`, you might need to use another installer (like `yum`)

xclip -sel clip < ~/.ssh/id_rsa.pub
# Copies the contents of the id_rsa.pub file to your clipboard
复制代码

复制上面的key后粘贴到github new key便可,以下图:编辑器
