1、在A服务器上远程查看B服务器上的信息
[oldboy@A ~]$ ssh 192.168.1.113 hostname B [oldboy@A ~]$ ssh 192.168.1.113 uname -r 2.6.32-431.el6.x86_64 [oldboy@A ~]$ ssh 192.168.1.113 uname -a Linux B 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux [oldboy@A ~]$ ssh 192.168.1.113 free total used free shared buffers cached Mem: 1020348 174508 845840 0 16092 61660 -/+ buffers/cache: 96756 923592 Swap: 1023992 0 1023992 [oldboy@A ~]$ ssh 192.168.1.113 uptime 07:03:23 up 5 min, 1 user, load average: 0.01, 0.08, 0.06 [oldboy@A ~]$ ssh 192.168.1.113 cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.5 (Santiago)
2、实现expect无交互式批量分发密钥到B、C,即在没有建立免密码认证之前分发密钥实现非交互批量发布。
执行:
[oldboy@B ~]$ ls fenfa_sshkey.exp fenfa_sshkey.sh iplist [oldboy@B ~]$ sh fenfa_sshkey.sh [oldboy@B ~]$ cat fenfa_sshkey.sh #!/bin/sh ./etc/init.d/functions for ip in `cat iplist` do # expect fenfa_sshkey.exp ~/.ssh/id_dsa.pub $ip >/dev/null 2>&1 expect fenfa_sshkey.exp ~/.ssh/id_dsa.pub $ip if [ $? -eq 0 ] then action "$ip" /bin/true else action "$ip" /bin/false fi done [oldboy@B .ssh]$ cat fenfa_sshkey.exp #!/usr/bin/expect if { $argc !=2 } { send_user "usage: expect fenfa_sshkey.exp file host\n" exit } #define var set file [lindex $argv 0] set host [lindex $argv 1] set password "lrz0412" #spawn scp /etc/hosts root@10.0.0.142:/etc/hosts #spawn scp -P52113 $file oldboy@$host:$dir #spawn ssh-copy-id -i $file "-p 52113 oldboy@$host" spawn ssh-copy-id -i $file "-p 22 oldboy@$host" expect { "yes/no" {send "yes\r";exp_continue} "*password" {send "$password\r"} } expect eof exit -onexit { send_user "bye!" }
