centOS无法使用git clone

想从码云上git clone上down一些源码，发现出现以下错误提醒

The authenticity of host 'gitee.com (116.211.167.14)' can't be established.

于是想起来git链接需要在码云上配置ssh公钥，点击码云设置

生成ssh公钥
1.你可以按如下命令来生成 sshkey:

ssh-keygen -t rsa -C "xxxxx@xxxxx.com"

2.按照提示完成三次回车，即可生成 ssh key。通过查看 ~/.ssh/id_rsa.pub 文件内容，获取到你的 public key

cat ~/.ssh/id_rsa.pub

3.复制生成后的 ssh key，添加到项目中。

4.添加后，在终端（Terminal）中输入

ssh -T git@gitee.com

5.简单的设置

git config --global user.name "yourname"
git config --global user.email "youremail@youremail.com"
