一、用ssh 带密钥文件登录时候，发生以下报错
[root@99cloud1 ~]# ssh -i hz-keypair-demo.pem centos@172.16.17.104
The authenticity of host ‘172.16.17.104 (172.16.17.104)‘ can‘t be established.
ECDSA key fingerprint is SHA256:HXYEa2IVBhTJ1AO+GDvROEvHM5ZRLgKxXsSaFmc6CNc.

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

二、修改密钥文件权限
[root@99cloud1 ~]# chmod 600 hz-keypair-demo.pem
[root@99cloud1 ~]# ip netns exec qdhcp-c2bc63d3-6ab2-4862-96f0-1a6d91df92f8 ssh -i hz-keypair-demo.pem centos@172.16.17.104
三、正常登录
[root@99cloud1 ~]# ssh -i hz-keypair-demo.pem centos@172.16.17.104
[centos@centos0130 ~]$ ip add
