3.ssh秘钥登录

[root@python1 ~]# ssh-keygen

 [root@python1 ~]# ssh-copy-id -i 192.168.202.131

 [root@python1 ~]# cd /root/.ssh/

[root@python1 .ssh]# ls

authorized_keys  id_rsa  id_rsa.pub  known_hosts

[root@python1 .ssh]# cat authorized_keys

[root@python1 ~]# netstat -an

root@python1 .ssh]# ssh python1 -p 8888
