scp上传本地文件到服务器，由于以前安装了服务器，之后卸载，再次安装，两次服务器ip相同，导致出现错误

scp F:/mysql-connector-java-8.0.19.tar.gz  root@192.168.145.128:/root/hua

Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.

解决方案

只需要将C:\\Users\\Administrator/.ssh/known_hosts文件删除，然后再次上传，错误就不再产生。

错误产生原因

因为以前产生的keys与现在的keys冲突，因此需要重新生成keys，不能用以前服务器的keys
