1.查看是否已经有了ssh密钥:cd ~/.ssh
如果没有密钥则不会有此文件夹,有则备份删除2.生存密钥: $ ssh-keygen -t rsa -C "邮箱" 按3个回车,密码为空。Your identification has been saved in /home/tekkub/.ssh/id_rsa.
Your public key has been saved in /home/tekkub/.ssh/id_rsa.pub. The key fingerprint is: ………………最后得到了两个文件:id_rsa和id_rsa.pub
id_rsa是RSA PRIVATE KEY,id_rsa.pub是公钥
