github clone "Permission denied (publickey). fatal: Could not read from remote repository."

 

LZ用git不久，第一次从github clone项目遇见一下问题

$ git clone git@github.com:xiaolongzuo/niubi-job.gitCloning into ‘niubi-job‘...Permission denied (publickey).fatal: Could not read from remote repository.

解决办法：

1.ssh -v git@github.com

   测试ssh连接是否成功，如LZ显示如下：

$ ssh -v git@github.com

2. ssh-agent -s

     

$ ssh-agent -s
SSH_AUTH_SOCK=/tmp/ssh-GTpABX1a05qH/agent.404; export SSH_AUTH_SOCK;
SSH_AGENT_PID=13144; export SSH_AGENT_PID;
echo Agent pid 13144;

 

 

3. ssh-add ~/.ssh/id_rsa

    

$ ssh-add ~/.ssh/id_rsa
Could not open a connection to your authentication agent.

 LZ这一步报错了，继续执行：eval `ssh-agent -s`

 无错请忽略以下步骤

$ eval `ssh-agent -s`
Agent pid 24460

   再次执行ssh-add ~/.ssh/id_rsa

$ ssh-add ~/.ssh/id_rsa
Identity added: /c/Users/Administrator/.ssh/id_rsa (/c/Users/Administrator/.ssh/id_rsa)

 

 

4.将客户端生成的key添加到github账户

 

   首先使用 clip < ~/.ssh/id_rsa.pub  或者文本编辑拷贝id_rsa.pub文本内容

    到github右上角账户管理-Setting下面找到左侧“SSH and
GPG keys”菜单，接着点击“Add SSH key”，在"title"栏输入一个自己喜欢的标题，“key”栏中粘贴刚刚复制的公钥内容，最后点击“Add key”按钮。

 

5.最后一步,验证key

$ ssh -T git@github.com
Hi JsonJu! You‘ve successfully authenticated, but GitHub does not provide shell  access.

 

接下来就可以愉快的去clone github上优秀的项目了。
