实现ssh免密码登陆管理的服务器
[apps@anza ~]$ sudo ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:

[apps@anza ~]$ sudo ssh-copy-id root@192.168.111.131
root@192.168.111.131‘s password:
Now try logging into the machine, with "ssh ‘root@192.168.111.131‘", and check in:
.ssh/authorized_keys
to make sure we haven‘t added extra keys that you weren‘t expecting.
