普通用户(xusj)进行免秘钥登陆步骤如下：
在主机A 192.168.1.1上操作
ssh-keygen -t rsa //参数公钥和私钥对，输入后一路回车。
Generating public/private rsa key pair.
Enter file in which to save the key (/home/xusj/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in/home/xusj/.ssh/id_rsa.
Your public key has been saved in /home/xusj/.ssh/id_rsa.pub.
将主机A的公钥拷贝至主机B的普通用户对应目录
ssh-copy-id -i ~/.ssh/id_rsa.pub xusj@192.168.1.2
然后输入主机B的xusj用户密码，此时主机B已经有主机A的公钥，因此此时主机A访问B已经不需要密码，可以直接登录
在主机A直接登录主机B，此时已经不需要输入秘钥：
ssh 192.168.1.2
