前提条件

以下两种推送的文件是SSH的公钥,推送方式依赖于SSH,基于SSH的相关方面操作和机器相关配置请参考我的上一篇博文“ssh服务批量管理例子


1、expect交互式方式

1、1上传文件及文件内容

#以10机器为例。

#执行rz –y分别上传“dis-sshkey”、“expect-copy-sshkey.exp”和“iplist”,三者文件内容如下:

[oldgirl@backup ~]$ ls -l dis-sshkey  expect-copy-sshkey.exp  iplist

-rw-r--r-- 1 oldgirl oldgirl 287 Jun  8 22:55 dis-sshkey

-rw-r--r-- 1 oldgirl oldgirl 579 Jun  8 22:55 expect-copy-sshkey.exp

-rw-r--r-- 1 oldgirl oldgirl  23 Jun 8 22:55 iplist


#dis-sshkey的内容如下:

[oldgirl@backup ~]$ cat dis-sshkey

#!/bin/sh
. /etc/init.d/functions
[ ! -f iplist ] && echo "hostlists.txt isnot exist." && exit 1
 
for host in `cat iplist`
do
 expectexpect-copy-sshkey.exp $host &>/dev/null
 if [ $? -eq 0];then
    action "$ipdis data" /bin/true
 else
    action"$ip dis data" /bin/false
 fi
done


 

#expect-copy-sshkey.exp的内容如下:

[oldgirl@backup ~]$ cat expect-copy-sshkey.exp

#!/usr/bin/expect
if { $argc != 1 } {  
 send_user"usage: expect expect-copy-sshkey.exp host \n"   
 exit   
} 
 
#define var
set host [lindex $argv 0]
set password "123456"
 
spawn ssh-copy-id -i /home/oldgirl/.ssh/id_dsa.pub"oldgirl@$host"
#spawn ssh -p 50718 disdata@$host /sbin/ifconfig 
set timeout 60
expect {
        -timeout 20
       "yes/no"    {send"yes\r";exp_continue}
       "*password" {send "$password\r"}
       timeout  {puts "expectconnect timeout,pls contact oldboy."; return}
}
expect eof
 
exit -onexit {
  send_user"Oldboy say good bye to you!\n"
}


#iplist的内容如下:

[oldgirl@backup ~]$ cat iplist

172.16.1.7

172.16.1.9


1、2安装expect

[root@backup ~]# rpm -qa expect

[root@backup ~]# yum install expect -y

[root@backup ~]# rpm -qa expect

expect-5.44.1.15-5.el6_4.x86_64

[root@backup ~]# which expect

/usr/bin/expect


1、3同步公钥操作

#先把79机器中已存在的公钥文件删除,不然再同步公钥的时候会失败。

[oldgirl@lnmp01 ~]$ rm -rf ~/.ssh/

[oldgirl@nfs-server ~]$ rm -rf ~/.ssh/

 

#在10机器执行

[oldgirl@backup ~]$ /bin/sh ~/dis-sshkey

 dis data                                                 [  OK  ]

 dis data                                                 [  OK  ]

 

#在79机器查看结果

[oldgirl@lnmp01 ~]$ ls -l ~/.ssh/authorized_keys

-rw------- 1 oldgirl oldgirl 604 Jun  8 23:26 /home/oldgirl/.ssh/authorized_keys

[oldgirl@nfs-server ~]$ ls -l ~/.ssh/authorized_keys

-rw------- 1 oldgirl oldgirl 604 Jun  8 23:26 /home/oldgirl/.ssh/authorized_keys


2、sshpass非交互式

2、1安装sshpass

[root@backup oldgirl]# cd /etc/yum.repos.d/

[root@backup yum.repos.d]# ll

total 24

-rw-r--r--. 1 root root 1991 Aug  4  2015CentOS-Base.repo

-rw-r--r--. 1 root root 647 Aug  4  2015 CentOS-Debuginfo.repo

-rw-r--r--. 1 root root 289 Aug  4  2015 CentOS-fasttrack.repo

-rw-r--r--. 1 root root 630 Aug  4  2015 CentOS-Media.repo

-rw-r--r--. 1 root root 6259 Aug  4  2015CentOS-Vault.repo

[root@backup yum.repos.d]# wgethttp://download.opensuse.org/repositories/home:/Strahlex/CentOS_CentOS-6/home:Strahlex.repo

#上述命令是在一行的。

[root@backup yum.repos.d]# yum install sshpass

 

2、2操作

[oldboy@backup ~]$ sshpass -p 123456 ssh 172.16.1.31

#第一次操作可能没反应,可用下述参数解决

[root@backup ~]# sshpass -p 123456 ssh -p 22 172.16.1.31 -o StrictHostKeyChecking=no

Warning: Permanently added ‘172.16.1.31‘ (RSA) to thelist of known hosts.

Last login: Fri Jun 10 15:32:52 2016 from 10.0.0.1

[root@nfs01 ~]# logout

[root@backup ~]# sshpass -p 123456 ssh 172.16.1.31 -o StrictHostKeyChecking=no

Last login: Fri Jun 10 15:57:47 2016 from 172.16.1.41

[root@nfs01 ~]# logout

2、2、1#直接带密码连接服务器

[root@backup ~]# sshpass -p 123456 ssh 172.16.1.31

Last login: Fri Jun 10 15:57:35 2016 from 172.16.1.41

[root@nfs01 ~]# logout

2、2、2#以文件形式保存密码连接服务器

[root@backup ~]# echo "123456">ssh.passwd

[root@backup ~]# sshpass -f ssh.passwd ssh 172.16.1.31

Last login: Fri Jun 10 16:00:06 2016 from 172.16.1.41

[root@nfs01 ~]# logout

Connection to 172.16.1.31 closed.

2、2、3#将密码写入变量

[root@backup ~]# export SSHPASS="123456"

[root@backup ~]# sshpass -e ssh 172.16.1.31

Last login: Fri Jun 10 16:05:14 2016 from 172.16.1.41

[root@nfs01 ~]# logout

Connection to 172.16.1.31 closed.

2、2、4#同理远程拉取、推送文件、执行命令等操作scp,rsync均可。

[root@backup ~]# sshpass -f ssh.passwd scp /etc/hosts172.16.1.31:/root/

[root@nfs01 ~]# pwd

/root

[root@nfs01 ~]# ls -l hosts

-rw-r--r-- 1 root root 158 Jun 10 16:13 hosts

[root@backup ~]# sshpass -f ssh.passwd ssh 172.16.1.31 ls /root/

anaconda-ks.cfg
