本機生成密鑰對
ssh-keygen -t rsa -f ~/.ssh/id_rsa -C "xxxx@163.com"
方式1
#上傳公鑰到遠程主機
scp ~/.ssh/id_rsa.pub root@139.199.xx.xx:/data/
#配置遠程主機
cat /data/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
方式2
ssh-copy-id -i ~/.ssh/id_rsa.pub root@139.199.xx.xx
問題1
ssh-copy-id方式報錯如下：

由于之前登錄過該臺云主機，而主機進行了系統(tǒng)重裝導致课兄。
刪除known_hosts關于該主機的記錄。
