Git代码仓库配置密钥SSH keys

当你在Git代码仓库，比如Github或者国内的码云Gitee，创建了一个仓库后，关联本地文件，可能出现以下情况：

• 仓库初始化

$ git commit -m "init page"
[master (root-commit) d832761] init page
 1 file changed, 7 insertions(+)
 create mode 100644 index.html

• 关联本地文件

$ git remote add origin git@github.com:xxxxx/xxxxx.github.io.git

• push remote仓库

$ git push -u origin master
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

• 失败，被告知没有访问权限，这是因为本机没有给代码仓库配置密匙
• 开始放大招，执行命令ssh-keygen -t rsa -C 你的邮箱地址，获取public 密匙

$ ssh-keygen -t rsa -C 你的邮箱地址
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
The key fingerprint is:
2c:03:89:09:5c:4c:2a:b9:2b:bd:ec:2b:a0:ce:ff:22 xxxxxxxxxx@qq.com
The key's randomart image is:
+--[ RSA 2048]----+

| +.+ .           |
|o.o o            |

• 根据路径找到id_rsa.pub文件，复制里面的内容，这里演示粘贴到Github的personal settings的SSH keys中

• 再一次push提交代码，成功，well done

$ git push -u origin master
Enter passphrase for key '/c/Users/Administrator/.ssh/id_rsa':
