为节点生成并配置密钥对

生成密钥对

[root@rancher-01 ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:sfL3YnyrNZsioS3ThuOTRME7AIyLxm4Yq396LAaeQOY root@rancher-01
