一、ssh链接服务器提示

The authenticity of host ' ' can't be established.
ECDSA key fingerprint is SHA256:.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

二、永久解决 | 屏蔽提示

1、打开文件

 sudo vi /etc/ssh/ssh_config 

2、修改文件内容

Host *StrictHostKeyChecking no

三、临时解决

ssh -o StrictHostKeyChecking=no cherry@10.110.19.2

这样操作引入了新的提示：

Warning: Permanently added '10.110.19.2' (ECDSA) to the list of known hosts.

消除引入提示

ssh -o StrictHostKeyChecking=no -o LogLevel=ERROR cherry@10.110.19.2
