I encountered the same problem with him.

ssh -i <your_keypair> root@<your_host> I tried this but it wasn't solved.

Here's my solution

host1 ip:192.168.1.21

host2 ip:192.168.1.22

host3 ip:192.168.1.23

on host1:

rm -rf /root/.sshssh-keygen -t dsacat /root/.ssh/id_dsa.pub >> /root/.ssh/authorized_keysscp /root/.ssh/id_dsa.pub host2:/root/scp /root/.ssh/id_dsa.pub host3:/root/

on host2:

rm -rf /root/.sshssh-keygen -t dsacat /root/id_dsa.pub >> /root/.ssh/authorized_keys

on host3:

rm -rf /root/.sshssh-keygen -t dsacat /root/id_dsa.pub >> /root/.ssh/authorized_keys

host1:/root/.ssh/id_dsa This's the file which you need.

过程如上，主要区别是：ssh-keygen -t dsa；

即dsa和rsa的区别。
