#### 原因分析 ####

Permission denied (publickey) 没有权限的publickey ，出现这错误一般是以下两种原因

*  客户端与服务端未生成 ssh key
 *  客户端与服务端的ssh key不匹配

找到问题的原因了，解决办法也就有了，重新生成一次ssh key ，服务端也重新配置一次即可。

#### 客户端生成ssh key ####

ssh-keygen -t rsa -C "470812087@qq.com"

[470812087@qq.com][470812087_qq.com]改为自己的邮箱即可，途中会让你输入密码啥的，不需要管，一路回车即可，会生成你的ssh key。（如果重新生成的话会覆盖之前的ssh key。）

然后再终端下执行命令：

ssh -v git@github.com

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l3bDQ3MDgxMjA4Nw_size_16_color_FFFFFF_t_70 2][]

最后两句会出现

1.  `　　No more authentication methods to try.`
2.  `　　Permission denied (publickey).`

在终端再执行以下命令

ssh-agent -s

接着在执行

ssh-add ~/.ssh/id_rsa

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l3bDQ3MDgxMjA4Nw_size_16_color_FFFFFF_t_70 4][]

$ ssh-add ~/.ssh/id\_rsa  
出现Could not open a connection to your authentication agent.  
这时可以使用：`ssh-agent bash` 命令，然后再次使用`ssh-add ~/.ssh/id_rsa_name`这个命令就没问题了。  
如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l3bDQ3MDgxMjA4Nw_size_16_color_FFFFFF_t_70 5][]

Identity added: ...这是ssh key文件路径的信息

#### 配置服务端 ####

打开你刚刚生成的id\_rsa.pub，将里面的内容复制，进入你的[github][]账号，在settings下，SSH and GPG keys下new SSH key，然后将id\_rsa.pub里的内容复制到Key中，完成后Add SSH Key。

**title随便起**

#### 验证Key ####

ssh -T git@github.com

1.  `$ ssh -T git@github.com`
2.  `Hi 470812087! You've successfully authenticated, but GitHub does not provide shell access.`
3.

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l3bDQ3MDgxMjA4Nw_size_16_color_FFFFFF_t_70 8][]

提示：Hi xxx! You've successfully authenticated, but GitHub does not provide shell access. 问题就解决啦
