04-配置远程仓库的SSH免密登陆

配置SSH免密登录

配置步骤

创建好的远程仓库也可以使用SSH的方式进行访问,但如果没有配置公钥会有警告

第一步: 删除用户家目录下的.ssh目录,如果没有该目录或者该目录下已经有密钥了就不用执行该操作

#进入当前用户的家目录,删除.ssh 目录
Layne@LAPTOP-Layne MINGW64 ~
$ rm -rvf .ssh
removed '.ssh/known_hosts'
removed directory '.ssh'

第二步: 在用户家目录下执行ssh-keygen -t rsa -C 邮箱命令生成.ssh文件(包含SSH公钥),不断回车即可,如果公钥已经存在则自动覆盖

• -t参数: 指定加密算法如rsa
• -C参数：要连接的Github/Gitee账号绑定的邮箱
• yes or no: 直接yes就可以得到ssh -T 绑定账号的邮箱

#在用户家目录下运行命令生成.ssh 秘钥目录
Layne@LAPTOP-Layne MINGW64 ~
$ ssh-keygen -t rsa -C [e-mail]
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Layne/.ssh/id_rsa):
Created directory '/c/Users/Layne/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Layne/.ssh/id_rsa.
Your public key has been saved in /c/Users/Layne/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:7CPfRLITKcYDhaqpEDeok7Atvwh2reRmpxxOC6dkY44 
[e-mail]
The key's randomart image is:
+---[RSA 2048]----+

#进入.ssh目录查看文件列表
Layne@LAPTOP-Layne MINGW64 ~
$ cd .ssh

第三步: 点击账号头像,点击设置添加公钥Setting-->SSH and GPG keys,配置公钥后再往远程仓库push东西的时候使用的就是SSH连接,此时就不需要登录验证了

第四步: ssh -T 绑定账号的邮箱查看是否认证成功
