 1 [root@nfs-server ~]# useradd luoahong
 2 [root@nfs-server ~]# echo 123456|passwd --stdin luoahong
 3 Changing password for user luoahong.
 4 passwd: all authentication tokens updated successfully.
 5 创建密码对:
 6 [root@nfs-server ~]# su - luoahong     ##切换到luoahong用户下,以后批量分发都在当前用户下,安全考虑
 7 [luoahong@nfs-server ~]$ ssh-keygen -t dsa ##ssh-keygen是生成秘钥的工具,-t参数指建立秘钥的类型,这里建立dsa类型秘钥(还有一种类型的秘钥为RSA,两者加密算法有区别)
 8 Generating public/private dsa key pair.
 9 Enter file in which to save the key (/home/luoahong/.ssh/id_dsa): 
10 Created directory ‘/home/luoahong/.ssh‘.
11 Enter passphrase (empty for no passphrase): 
12 Enter same passphrase again: 
13 Your identification has been saved in /home/luoahong/.ssh/id_dsa.
14 Your public key has been saved in /home/luoahong/.ssh/id_dsa.pub.
15 The key fingerprint is:
16 6f:65:c4:a6:fb:32:45:0c:85:c3:bc:87:8f:a4:ae:bc luoahong@nfs-server
17 The key‘s randomart image is:

2.1在NFS上测试

2.1.1 通过ssh命令在当前机器上查看web-lamp01的IP地址

 1 [luoahong@nfs-server ~]$ ssh -P22 luoahong@10.241.58.12 /sbin/ifconfig eth0
 2 eth0      Link encap:Ethernet  HWaddr 00:0C:29:49:CE:B3

10 注:在命令执行过程中,跳过输入密码的步骤
11 接着分发文件测试:
12 [luoahong@nfs-server ~]$ cp /etc/hosts
13 hosts        hosts.allow  hosts.deny   
14 [luoahong@nfs-server ~]$ cp /etc/hosts .
15 [luoahong@nfs-server ~]$ ll
16 [luoahong@nfs-server ~]$ scp -P22 hosts luoahong@10.241.58.12:~ ##将当前目录下hosts文件分发到1.12家目录下
17 hosts                                          100%  243     0.2KB/s   00:00    
18 [luoahong@nfs-server ~]$ 
19 
20 检查1.12上luoahong家目录下有无hosts文件
21 [root@lamp01 luoahong]# cat /home/luoahong/hosts 
22 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 
23 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
24 10.241.58.11 nfs-server
25 10.241.58.17 backup
26 10.241.58.12 lamp01
27 10.241.58.13 lnmp02
28 [root@lamp01 luoahong]# 
29 通过脚本分发:
30 [luoahong@nfs-server ~]$ sh fenfa.sh
31 hosts                                          100%  257     0.3KB/s   00:00
