【sublime xftp插件】 Host key verification failed ，错误处理

错误背景：

1、CentOS7上面作为运行环境，Coding在本机的windows环境

2、在windows上安装sublime 3，然后保存代码通过xftp保存到centos7虚机上面。

3、Centos重装系统后，把代码保存的目录调整了一下

4、然后时间sublime 下载新目录的代码，然后就报错了

错误内容：

Connecting to SFTP server "www.xxxx.club" as "root" ............... failure (Host key verification failed)
The SSH host key has changed. This could indicate a potential security breach, or that the domain you are connecting to recently moved servers.
If you are confident this is not a security breach you can delete the old host key and try again.
 1. Win XP: Start > Run > regedit.exe
    Win Vista/7: Start > regedit
 2. Expand to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys and delete the entry including @22:www.xxxx.club

　原因：因为sublime 在windows的注册表中把www.xxxx.club的值注册，不能重新注册。

错误解决办法：

1、ctrl + R ，输入  regedit

2、删除HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys下的@22:www.xxxx.club
