笔者操作系统是ubuntu 14.04
运行下面的命令创建SSH Key
ssh-keygen -t rsa -C "byhook@163.com"
邮箱为github登陆邮箱
然后根据提示输入github密码
Generating public/private rsa key pair.
Enter file in which to save the key (/home/byhook/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/byhook/.ssh/id_rsa.
Your public key has been saved in /home/byhook/.ssh/id_rsa.pub.
The key fingerprint is:
f5:9a:53:d3:97:d1:61:11:81:f6:9a:53:e1:c2:ab:62 byhook@163.com
The key's randomart image is:
+--[ RSA 2048]----+
| .*+|
| o..o|
| . o o.o|
| . . + +o|
| S + B..|
| + * . |
| + . . |
| E o |

生成的id_rsa文件是私有密钥
id_rsa.pub是公开的密钥
查看公钥的内容
cat ~/.ssh/id_rsa.pub
输出结果
ssh-rsa 公钥内容 byhook@163.com
复制上述的内容
使用私钥和github进行认证
ssh -T git@github.com
结果显示
The authenticity of host 'github.com (192.30.252.131)' 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,192.30.252.131' (RSA) to the list of known hosts.
Hi byhook! You've successfully authenticated, but GitHub does not provide shell access.
成功!!!
如果出现下图问题
Warning: Permanently added the RSA host key for IP address '192.30.252.131' to the list of known hosts.
Agent admitted failure to sign using the key.
Permission denied (publickey).
输入命令
ssh-add
输入密码
继续即可
使用SSH Key访问github
输入命令
git remote set-url origin git@github.com:byhook/IPCSample.git
OK
以后操作都不用输入密码了
