xiluhua@vm-xiluhua ~/.ssh $ ssh-copy-id -i id_rsa.pub loginuser@10.1.118.45

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

xiluhua@192.168.178.132's password: 

Number of key(s) added: 

Now try logging into the machine, with: "ssh 'loginuser@10.1.118.45'"

and check to make sure that only the key(s) you wanted were added.

scp -p ~/.ssh/id_rsa.pub loginuser@10.1.118.45:/home/weblogic/.ssh/authorized_keys

实在不行，手动复制到目标机器上也可以

xiluhua@vm-xiluhua ~/.ssh $ ssh loginuser@10.1.118.45
