ssh-keygen -t rsa
for i  in {2..5} ;do
    /usr/local/bin/sshpass  -p 123123 ssh root@192.168.2.$i "mkdir .ssh"
    /usr/local/bin/sshpass  -p 123123 scp /root/.ssh/id_rsa.pub 192.168.2.$i:/root/.ssh/id_rsa.pub
    /usr/local/bin/sshpass  -p 123123 scp /root/.ssh/authorized_keys  192.168.2.$i:/root/.ssh/authorized_keys
    sshpass -p 123123 ssh root@192.168.2.$i "cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys"
done

ps：sshpass需要自行安装
