Permission denied (public key)

一 、设置Git的user name和email：

$ git config --global user.name "xuhaiyan"

$ git config --global user.email "xxxxxx@gmail.com"

（引号中自己的名字和邮箱）

二、生成SSH密钥过程：

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 “xxxxx@gmail.com”

按3个回车，密码为空。

Your identification has been saved in /home/xxx/.ssh/id_rsa.

Your public key has been saved in /home/xxx/.ssh/id_rsa.pub.

The key fingerprint is:

………………

最后得到了两个文件：id_rsa和id_rsa.pub

3.添加密钥到ssh：ssh-add ~/.ssh/id_rsa

需要之前输入密码。

4.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/，登陆xuhaiyan825，然后添加ssh。

5.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.

查看密钥：

1、查看ssh文件夹

      ls ~/.ssh/

2、进入到ssh文件夹

      cd .ssh

3、查看密钥（要复制要服务器的那个）

      more id_rsa.pub
