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

第一次使用然后，，出现上述问题

解决办法均来自互联网：

设置Git的user name和email

git config –global user.name “yourname”
git config –global user.email “youremail”
生成SSH密钥

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
生存密钥：
ssh-keygen -t rsa -C “haiyan.xu.vip@gmail.com”
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
添加密钥到ssh：ssh-add 文件名,需要之前输入密码.

在github上添加ssh密钥，这要添加的是“id_rsa.pub”里面的公钥。
打开https://github.com/,在设置中添加密钥

测试：ssh git@github.com
The authenticity of host ‘github.com (207.97.227.239)’ can’t be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘github.com,207.97.227.239′ (RSA) to the list of known hosts.
ERROR: Hi tekkub! You’ve successfully authenticated, but GitHub does not provide shell access
Connection to github.com closed.

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

1. 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;

1. 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

[plain] view plain copy
$ eval ssh-agent -s
Agent pid 24460
再次执行ssh-add ~/.ssh/id_rsa

[plain] view plain copy
$ 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

[plain] view plain copy
$ 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。

当采用第二种办法时遇到没有文件夹的时候，我们就应该采用第一种办法建立文件夹
