解决HEXO Git部署时报错：Permission denied (publickey)

平台：Win10

很久没有更新文章了，断更期间还重装了系统:D

于是乎今天用HEXO部署文章时报错了：

Permission denied (publickey)

错误原因就是字面意思，SSH Key没有配置好。

首先在Git Bash中检查是否有SSH Key：

$ ssh -T git@github.com
git@github.com: Permission denied (publickey).

嗯，没有。

那就新建一个吧：

$ ssh-keygen -t rsa -C "example@qq.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/xiaoming/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/xiaoming/.ssh/id_rsa.
Your public key has been saved in /c/Users/xiaoming/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:pdmmm0dTm/sssss5xoPmY82FCHznLngEbC5iEtpKkba example@qq.com
The key's randomart image is:
+---[RSA 2048]----+
|o.. . o.o        |
|o+.. . + .       |
|ooo       o +    |
|Eo       B = *   |
|.       S = = o  |
|       o # * o   |
|        O / *    |
|       . * = .   |
|                 |
+----[SHA256]-----+

执行过程中要求输入口令，直接回车就好，无伤大雅。然后登录GitHub在账户的设置中找到SSH and GPG keys，点击New SSH Key新建SSH Key，将c/Users/xiaoming/.ssh/id_rsa.pub文件内的公钥粘贴进去即可。

再次检查：

$ ssh -T git@github.com
Warning: Permanently added the RSA host key for IP address '13.250.177.223' to the list of known hosts.
Hi Xiaoming! You've successfully authenticated, but GitHub does not provide shell access.

OK，再次部署就成功了。
