Today, when using git to operate remote service, prompt the remote host to identify the modification

SHA256:----------------------------------.
Please contact your system administrator.
Add correct host key in /Users/dyz/.ssh/known_hosts to get rid of this message.

The reason is that the system of Alibaba cloud host was reinstalled yesterday, which caused the remote host information stored in this machine to change. According to the above prompt, enter/users/dyz /. SSH, edit and open known_ Hosts file. I have only connected to one remote host here, so I delete all the contents in it. After saving, I will link to the remote host again by git operation

Are you sure you want to continue connecting (yes/no)?

Enter yes
