有时候准备pull的时候却发现密码怎么输也输不对，提示的信息是没有权限或者密码错误，如下

如果出现以上类似的报错提示的话不妨试一下生成ssh－key的方法。步骤如下
在终端输入
|
1
|
ssh-keygen -t rsa -C
"Bear Xiong"
//注意。Bear Xiong为用户名
|
如果执行成功。返回
|
1
2
|
Generating
public
/
private
rsa key pair.
Enter file in which to save the key (/home/forwhat.cn/.ssh/id_rsa):
|
后面的提示都可以直接回车

Your identification has been saved in /Users/robin/.ssh/id_rsa.
Your
public
key has been saved in /Users/robin/.ssh/id_rsa.pub.
//注意这一行是key存放的地址，带会会用到
The key fingerprint is:
ee:c6:b9:1b:1c:b8:7d:81:fa:32:26:ae:1c:67:99:49 Bear Xiong
|
再次回车。

The key's randomart image is:
+--[ RSA 2048]----+

| |
| |
| o |
| + . S |
| . = . o |
| o + +o.o |
|E o . o.=+. |
|.+ ==+ooo. |
+-----------------+
|
这样SSH key就生成了。
|
1
|
vi /Users/robin/.ssh/id_rsa.pub
|
把刚才上面显示的存储的地址放在vi编译器里运行会生成如下代码

把刚才复制的贴到git的公钥那一栏里，就ok了。
