github上的开源项目,在ubuntu系统中无法进行clone,通过在网站上注册账户,用命令生成ssh 公钥和私钥,把公钥添加到网站账户中可解决这个问题
1.产生ssh key
ssh-keygen -t rsa -b 4096 -C "xuyuan_77@163.com"
2.复制产生的pub key
若没有安装xclip的话,先安装。命令如下
sudo apt-get install xclip
用命令复制:
xclip -sel clip root/.ssh/id_rsa.pub
然后再去github 网站上添加,网站上有帮助,就不细讲了。
3.进行验证
ssh -vT git@github.com
4.把私钥加入ssh
ssh-add ~/.ssh/id_rsa
完整过程如下:
root@ubuntu:~/.ssh# ssh-keygen -t rsa -b 4096 -C "xuyuan_77@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa 注意:此处不要更改其默认目录,不然验证的时候找不到private key,以至于验证通不过。至少我碰到了这个问题
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:rp5yIWGjih6xdd9Eo775MkVgFrCAQENWoFikQ25FsWw xuyuan_77@163.com
The key's randomart image is:
+---[RSA 4096]----+
