超新星小白勇闯github -ssh

作为一枚超新星编程小白，在使用github时发生了许多小插曲。
今天分享一下如何设置ssh key
设置好了之后就可以将github上的代码包直接使用"ssh git xxx"命令远程下载在本地了哦！！
centos8 生产环境

生成本地SSH key

[root@s_182 ~]# cd ~/.ssh
[root@s_182 .ssh]# ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
[root@s_182 .ssh]# cat id_rsa.pub
ssh-rsa AAAAB3....(省略)....c= root@s_182

将id_rsa.pub上所有的内容复制粘贴到github上
执行

[root@s_182 ~]# ssh -vT git@github.com

插曲来了！！！出现问题了

[root@s_182 ~]# ssh -vT git@github.com
OpenSSH_8.0p1, OpenSSL 1.1.1k  FIPS 25 Mar 2021

别慌，写一个config，主要是指定一下端口

[root@s_182 ~]# cd ~/.ssh
[root@s_182 .ssh]# vim config

[root@s_182 .ssh]# cat config

Host github.com
User “邮箱xx@xx.com”
Hostname ssh.github.com
Port 443

继续执行

[root@s_182 ~]# ssh -vT git@github.com
