步骤
ssh-keygen -t rsa -C "[email protected]"
在本地生成 rsa 公私钥。直接回车。名称必须是默认的id_rsa。
将公钥保存到 github / gitee
ssh -T [email protected]
如果正常会返回
Hi XXX! You've successfully authenticated 之类的
当然我们这里遇到的是
sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).

如果看到以下Permission denied (publickey) 结尾

Permission denied (publickey).
解决办法通过 ssh-add
eval "$(ssh-agent -s)"
我们会看到：
Agent pid xxxxx
继续执行
ssh-add
显示如下即成功：
Identity added: /home/xxx/.ssh/id_rsa (/home/xxx/.ssh/id_rsa)
