Git SSH 配置

Tips: Github about ssh

这两天在搭建Github博客，在配置ssh时遇到了一些坑，网上的很少写得齐全，第一篇博客就把这个坑填上吧。

Tips: 本次配置在Windows环境下，使用git bash。Linux下命令基本一致。

步骤

1. 查看本地是否存在ssh

1
2
$ cd ~/.ssh
$ ls -al ~/.ssh

2. 生成 ssh key

1
$ ssh-keygen -t rsa 4096 -C "your_email@example.com"

Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Hunter/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Hunter/.ssh/id_rsa.
Your public key has been saved in /c/Users/Hunter/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:7KwlOZ4yljBZE2ZJ7dr8QGIyQeiPk49L+01fnC0hAZY your_email@example.com
The key's randomart image is:
+---[RSA 4096]----+
| o...=.          |
|. . *Eo          |
|.  + o .         |
| .o = o..        |
|  +* B .S.       |
| ++.. ++o +      |
| .+o o+o+= .     |
|....B..*o .      |
| ooo ++.         |
+----[SHA256]-----+
Tips: 双引号内填保存在github段的邮箱

3. 将key添加到ssh-agent(很重要)

先确认ssh-agent是可用的

1
$ eval $(ssh-agent -s)
1
Agent pid 13140

将ssh key添加到ssh-agent

1
$ ssh-add ~/.ssh/id_rsa
1
Identity added: /c/Users/Hunter/.ssh/id_rsa (/c/Users/Hunter/.ssh/id_rsa)

4. 将ssh public key添加到github

复制public key内容

1
$ clip < ~/.ssh/id_rsa.pub

登录github->选择Settings->SSH keys->New SSH key

将public key内容复制上去，并命名

5. 测试ssh key

1
$ ssh -t git@github.com
1
2
Warning: Permanently added the RSA host key for IP address '192.30.252.128' to the list of known hosts.
PTY allocation request failed on channel 0

配置完毕

这时就可以进行clone等操作了
