如何给 GitHub 添加  SSH key， 如何生成  SSH key 详细图文教程！

一、 生成  SSH key

https://ide.c9.io/xgqfrms/

创建一个空项目：(或使用真实 Linux 主机) PS： windows 类似（？ CMD） ReadMore

https://ide.c9.io/xgqfrms/demo

打开 shell(bash), 输入：

$ npm install -g git-it

生成 SSH-Key

$ ssh-keygen -t rsa -b 4096 -C "username@email.com"

检查，添加 ssh-key 到，linux client:

$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/id_rsa

复制 ssh-key public 到 剪切板：

$ clip < ~/.ssh/id_rsa.pub

如果不好使， 使用vim 打开，复制即可！

$ cd /home/ubuntu/.ssh/

$ ls -l

$ vim id_rsa.pub

PS: 退出 vim 方法：

1. 点击 esc 键，进入vim命令模式 输入 :q

：q

2. 点击 Enter 即可退出！

NEW:   after add ssh key ,you should close the terminal & restart a new terminal!

二、 给 GitHub 添加  SSH key

1. 打开 设置>SSH and GPG Keys> New SSH key ,

2. 将复制的 id_rsa.pub 的 key 值，粘贴到 key 文本框，点击 Add SSH key 即可!

ok!

NEW:   after add ssh key ,you should close the terminal & restart a new terminal!

Generating a new SSH key and adding it to the ssh-agent

• MAC
• WINDOWS
• LINUX

After you've checked for existing SSH keys, you can generate a new SSH key to use for authentication, then add it to the ssh-agent.

Generating a new SSH key

1. Open Terminal.

2. Paste the text below, substituting in your GitHub email address.

   ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
   # Creates a new ssh key, using the provided email as a label
   Generating public/private rsa key pair.
   

3. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

   Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]
   

   using new path in case of override your other SSH-keys
    Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]

   

   $ Enter a file in which to save the key (/Users/you/.ssh/id_rsa): /Users/you/.ssh/id_rsa_github [Type a passphrase]
   

4. At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases".

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

Adding your SSH key to the ssh-agent

Before adding a new SSH key to the ssh-agent, you should have checked for existing SSH keys andgenerated a new SSH key.

1. Ensure ssh-agent is enabled:

   # start the ssh-agent in the background
   $ eval "$(ssh-agent -s)"
   Agent pid 59566
   

2. Add your SSH key to the ssh-agent. If you used an existing SSH key rather than generating a new SSH key, you'll need to replace id_rsa in the command with the name of your existing private key file.

   $ ssh-add ~/.ssh/id_rsa
   

3. Add the SSH key to your GitHub account.
